To buy copper tube from Taban Mes Iranian, you can proceed in two ways: 1) Directly contact the company’s sales department via the published phone numbers or the official email. The sales specialists will provide consultation, issue a pro forma invoice for your order, and after your approval, arrange for the dispatch of the goods.

2) In‑person or online purchase: If the company has a physical store or an online ordering website, you can place your order by visiting the sales office or the official website (if an online ordering section exists). In both cases, you need to specify the product details (type of copper tube, size, wall thickness, required quantity). After agreeing on the price and terms, payment is made (usually as a down payment or according to the contract), and then the goods are shipped via freight companies or other trusted carriers of the company to your address. It is recommended that, before purchasing, you verify the company’s authenticity and contact numbers and, if possible, take advantage of the company’s free technical consultation to choose the best option.

 Yes. Most major manufacturers and suppliers of copper tube—including Taban Mes Iranian—are able to ship orders to all provinces and cities across Iran. These companies typically have cooperation agreements with reputable carriers and, after secure packaging, dispatch customer orders to the buyer’s destination via truck, trailer, or pickup. Delivery time depends on the distance to the destination city and the order volume (typically between 1 to 3 business days within nearby provinces and up to one week for more distant locations). Shipping costs are calculated based on the order’s weight/volume and distance and are usually borne by the buyer (unless special sales terms such as free shipping for bulk orders have been offered). With nationwide shipping experience, Taban Mes Iranian insures the shipment so that, in the event of potential transit damage, the buyer is not exposed to concern. Customers can obtain the waybill tracking code from the sales department and track the status of their shipment.

 Buyers can assess copper tube quality in several ways: 1) Visual inspection: A high‑quality copper tube has a smooth, bright outer surface (or the natural slightly matte look of copper) with no dents, cracks, or corrosion spots. Its inner surface is clean and free of chips. The tube should also be perfectly round (roundness of the cross‑section) and uniform; ovality or wall‑thickness variation along the length indicates poor manufacturing quality. 2) Markings and standards: Reputable manufacturers usually engrave or print their brand name and the production standard number (e.g., ASTM B280 or EN12735) on each straight length or on the coil label. The presence of these markings and their consistency with the certificates provided indicate that the tube is genuine and produced to standard. 3) Flexibility (for soft coils): A good‑quality annealed copper tube can be bent relatively easily without hairline cracks appearing on the surface or excessive spring‑back. If, during bending, the tube cracks or wrinkles significantly, it may indicate an inferior alloy or improper heat treatment. 4) Weight and wall thickness: Measure the weight per unit length of the tube and compare it with standard values. For any given size, if the weight is much lower than the standard, the wall may be thinner than allowed or the material may contain impurities. 5) Laboratory consultation: For sensitive projects, a sample can be sent to a laboratory to check chemical composition (to ensure copper purity) and perform mechanical tests (tension, hardness). This is recommended mainly for bulk purchasers. In general, buying from reputable brands (high‑quality) is the best way to ensure quality. Brands such as Bahonar, Babak, Mehr Asl, and Ghaem have a strong track record of quality and produce in accordance with standards. By contrast, off‑brand or very cheap copper tubes may be produced from low‑purity scrap melts, which are often more brittle and prone to leakage and corrosion. Therefore, always ask the seller for the product’s analysis certificate and compliance certificate, and pay attention to the appearance and the name stamped on the tube.

Hard (rigid or hard‑drawn) and soft (annealed) copper tubes are made of the same material (pure copper); their difference lies in the manufacturing process and the resulting mechanical properties. After being drawn to final size, a hard copper tube is not annealed; thus, the copper’s grain structure remains cold‑worked, which gives it higher strength and hardness. These tubes are typically offered as straight lengths. The advantage of hard tube is higher strength and greater pressure tolerance, while its drawback is low flexibility; bending requires a bending spring or a hydraulic tube bender (or the use of angled fittings).

In contrast, after final drawing, a soft copper tube undergoes annealing (controlled heating followed by slow cooling). Annealing relieves internal stresses in the copper and makes it soft and malleable. Therefore, soft tube has high flexibility and can be bent easily by hand or with hand tools without cracking. These tubes are often supplied in coils. In terms of pressure resistance, hard tubes typically tolerate slightly higher pressures (because the yield stress of un‑annealed copper is higher), but for many common applications both types operate safely within system working pressure ranges. The choice between the two depends on the application: for fixed and straight runs (e.g., building water or gas risers, fixed piping in cold rooms) where strength and stable form are required, hard tube is preferred; but for variable connections and on‑site routing (such as connecting the indoor and outdoor units of split A/C systems, or tortuous concealed piping), soft tube is preferred due to easy, joint‑free installation. It is worth noting that, in terms of price, annealing may add a small cost, but there is usually not much market price difference between straight lengths and coils; most of the cost is determined by the copper weight.

 Copper tubes can be categorized by form of supply and application: (1) Straight (length) copper tube: 6‑meter hard (rigid) lengths used for water and gas piping, central heating, refrigerant lines in chillers and cold rooms, and general industrial/building applications. These require fittings to change direction and are available in diameters from 6 to 108 mm (approximately 3/8 to 4 inches). (2) Coiled (pancake) copper tube: soft, annealed tubes wound in 15, 30, or 50‑meter coils. They are mainly used in split air‑conditioners, refrigerators, combi‑boilers, inter‑tank connections, etc., where the run must be flexible and joint‑free. Typical coil sizes range from 1/8 to 7/8 inch. (3) Industrial coil (LWC – Level Wound Coil): long, continuous coils used in manufacturing; for example, producers of heat exchangers (radiators) or HVAC use these on production lines for automated bending and cutting. (4) Capillary tube: very small‑bore tubes (1 to 3 mm OD) used to reduce pressure in refrigeration cycles (e.g., refrigerator capillary). These are supplied in small coils. (5) Internally grooved or externally finned copper tube: specialty tubes with longitudinal internal grooves or short external fins to increase heat‑transfer surface area. They are used in high‑efficiency HVAC systems (e.g., new‑generation A/Cs and solar water‑heater coils) to boost thermal performance. (6) Copper‑alloy tubing (e.g., brass): strictly speaking outside the scope of pure copper, but sometimes used in industry (e.g., brass tube for specific marine or decorative uses). Accordingly, each type has its own application: straight lengths for fixed, straight runs; coils for flexible connections; LWC for industrial mass production; and capillary for refrigerant flow control in refrigeration units. Knowing these types helps you choose the right material for your project.

In Iran’s market, several reputable copper‑tube brands exist (e.g., Bahonar, Babak, Mehr Asl, Ghaem, …), all producing standard, high‑quality products. Key differences across brands include production method, production capacity, form of supply, and after‑sales service. For example, Bahonar has a longer track record with an annual capacity of about 5,000 tons, whereas Babak—using more modern technology—has a capacity of 12,000 tons and can produce a wider range (e.g., thinner walls). In terms of material quality and copper purity, all these brands use standard copper cathode (99.95%), so there is no notable difference in the final product’s chemical composition. However, manufacturing process quality may create slight differences; for instance, copper tube made by continuous casting (by Babak or Ghaem) may exhibit better dimensional uniformity than tube produced by extrusion. That said, all leading domestic brands manufacture to international ASTM and EN standards and pass quality tests. Therefore, from the end user’s perspective, there is no major difference in the performance of tubes from different brands.

Most brand differentiation lies in services: some accept custom cut‑to‑length orders or special long coils; availability of certain sizes may be better from one brand than another. Packaging and presentation can also differ (carton vs. plastic wrap). Price differences among top‑tier brands are usually slight and track the daily copper price. If you have worked with a brand and been satisfied, it is reasonable to continue; otherwise, provided authenticity is verified, you can buy from any reputable brand with confidence, as they have all proven themselves. In short, reputable domestic brands are more similar than different; the choice mostly comes down to availability and trust in the supplier.

For split A/C installation, coiled (pancake) copper tube is used because the indoor and outdoor units must be connected by flexible tubing. The required tube size depends on the A/C capacity. Typically, two copper tubes are used: a smaller one for liquid refrigerant (liquid line) and a larger one for vapor/suction (suction line). For example: 9,000–12,000 BTU units commonly use 1/4‑inch (6 mm) and 3/8‑inch (10 mm); 18,000–24,000 BTU units use 1/4 & 1/2 inch or 3/8 & 5/8 inch; and larger units of 30,000 BTU and above may require 3/8 & 3/4 inch. The exact sizes are specified in each unit’s manual. These tubes must be soft, annealed (coiled) so the installer can route and bend them easily through building passages. It is also advisable to procure ACR‑grade copper tube—clean, dry interior, capped at both ends. Brands such as Mehr Asl, Babak, Ghaem, and Bahonar all produce suitable coils for A/C. Another key factor is wall thickness; for inverter A/Cs with higher refrigerant pressures, a slightly thicker wall (e.g., 0.80 mm instead of 0.63) is preferred for assured pressure resistance. Overall, annealed 1/4‑ and 3/8‑inch copper tubes are the most common for household split installs. Line length should follow the manufacturer’s recommendations (typically max 10–15 m), and extra refrigerant must be added if longer runs are used. In short: “soft, coiled copper tube with sizes matched to unit capacity and adequate wall thickness” is the best choice. Don’t forget to insulate the lines after installation—especially the suction line—to prevent sweating and energy loss.

: Medical gas piping systems in hospitals (oxygen, nitrous oxide, surgical compressed air, vacuum, …) must use medical‑grade copper tube. These tubes are typically manufactured to BS EN 13348 or an equivalent standard dedicated to copper tubes for medical gases. The critical features are high purity and internal cleanliness. Hospital piping is usually done with hard (straight‑length) copper because runs are fixed and dimensional stability matters more than flexibility. These are commonly supplied in 6‑meter lengths. The copper used should be 99.99% pure and free of oil/grease. Reputable manufacturers clean the tube interior with dry air and then seal both ends of every length with fully airtight caps so the interior remains clean and sterile until installation. Tube sizes are selected per system design; for main oxygen trunks, 15 or 22 mm are common, and 8 or 10 mm suffices for bed drops. This product is often called “hospital copper tube.” Domestic brands such as Ghaem and Bahonar offer suitable tubes for medical gases (often labeled as degreased copper tube). Such tubes must come with analysis and pressure‑test certificates. Another important point is the joining method: joints must be silver‑brazed or otherwise lead‑free so no contaminants enter the breathing‑gas stream.

After installation, the medical gas piping must be leak‑tested with an inert gas (nitrogen) and then fully evacuated (vacuumed) to ensure the system is clean and leak‑free. In short, for medical service use “medical‑standard, hard, clean, capped copper tubes” and follow hygienic installation practices precisely to safeguard patient health.

Unlike iron, copper does not form the red or orange‑brown rust seen on steel; instead, a layer of copper oxide (dark brown) gradually forms on its surface, which in fact acts as a protective film. In certain environments this layer may turn green (patina or copper carbonate), as seen on some old copper structures. In typical municipal water, copper pipe corrodes very slowly. However, two types of corrosion can occur under certain conditions: (1) Pitting corrosion: if the water contains small amounts of sulfide or ammonia, or has very low acidity (very pure/low‑mineral water), microscopic pits may rarely develop in the inner wall of the copper tube. This usually occurs in stagnant or low‑flow sections and may, after years, lead to pinhole leaks. The control measure is to adjust the water’s pH and remove corrosive species. (2) Galvanic corrosion: if copper is in direct contact with dissimilar metals such as steel or aluminum in the presence of an electrolyte (e.g., water), a galvanic cell forms in which the nobler metal (copper) is protected and the more active metal is consumed. Copper itself is comparatively safe in this case, but, for example, galvanized‑iron fittings connected to copper may become the sacrificial element. To prevent this, always use a dielectric union or PTFE tape between copper and other metals. Overall, copper is highly resistant to most forms of corrosion, which is a major reason for its use in piping. Copper does not suffer from surface rust that flakes or scales off like iron, and its oxide layer is stable. In sewage or seawater—where chlorides are high—copper may experience a small rate of uniform corrosion, but it still performs much better than plain carbon steel. Therefore, if the service environment is not highly aggressive, one can say copper pipe “does not rust” in the colloquial sense and will remain leak‑free for decades. For extra assurance, the pipe can be insulated or corrosion inhibitors can be used in the fluid, although in most cases this is unnecessary.

Copper pipes can be joined in several ways, and the choice depends on the application and the equipment available. The most common method is soldering/brazing. For thin‑wall copper (e.g., domestic water piping), soft soldering with tin alloys used to be employed (as in older copper water systems), but nowadays hard soldering (brazing) with fillers such as 5% silver or phosphorus‑silver is more common. In this method, a male‑to‑female joint (a fitting, or the end of one tube expanded with a swaging/expander tool to receive the other) is assembled and heated with an oxy‑acetylene or propane torch until the silver filler melts and wicks into the gap between the two tubes. After cooling, the joint is very strong and tight, and it can withstand high pressure and temperature.
Another approach is to use threaded or press‑type fittings. Some systems (e.g., chillers or vacuum pumps) require mechanical screw connections in which the tube end is flared and then secured with a flare nut to a threaded fitting (like the flare‑and‑nut connections between air‑conditioner lines and service valves). In addition, there are now mechanical press fittings specifically for copper: a hydraulic press tool crimps the fitting onto the pipe, and sealing is provided by an internal O‑ring. This method is fast, flame‑free, and used for copper water and fire‑fighting lines. For very small‑diameter copper (capillary tube), joints are typically made with soft solder or dedicated push‑in/compression micro‑fittings.
The critical points when joining copper are cleaning and fluxing: before soldering, the tube surfaces should be abraded with fine emery and a suitable flux applied to remove oxides and promote wetting. After the joint is made, any residual flux should be cleaned off to avoid corrosion. In general, correctly performed brazing provides the strongest and most reliable copper‑to‑copper joint; if done properly, the joint will last as long as the pipe itself.
That said, flame‑free methods may be preferred depending on project constraints (for example, where hot‑work is hazardous or job speed is critical, press fittings are chosen). In high‑pressure, high‑temperature systems (such as refrigerant lines), always use hard‑brazing with a silver‑bearing filler, and be sure to purge the inside of the tube with nitrogen during heating so that soot and oxides do not form.

Yes, copper pipe—especially annealed soft types—has excellent bendability. Even hard copper tube can be bent with suitable techniques. To bend copper properly without cracking or flattening, you need the right tools. A manual spring bender is one of the simplest tools for small tubes (up to 1/2 in.): insert a spring matched to the tube’s diameter inside the tube, then gently bend it by hand. The spring helps prevent excessive ovality and wrinkling on the inside of the bend. For larger sizes or when many bends are required, lever‑type or hydraulic tube benders are used. These machines have form dies with standard bend radii; the tube is set in the machine and, by pulling the lever or using the hydraulic pump, is formed around the die to produce a smooth, even bend.
In professional shops the tube may even be heated before bending (especially with thick‑wall or hard‑drawn copper); heating to a dull‑red temperature softens the metal and makes bending easier (although after cooling it will harden again unless it is fully annealed). When bending, the bend radius should be at least 3 to 4 times the tube diameter to avoid damage. Keep the bending motion steady and avoid bending back and forth (bending and re‑straightening), which can cause cracking. Annealed coil tubing can be bent to some degree by hand, but for tight angles a spring or a proper bender is recommended so the finish looks clean.
A practical tip: if a spring isn’t available, you can completely fill the tube with fine sand and cap both ends before bending; the sand helps resist wrinkling. After bending, empty the sand and clean the tube. Overall, copper is a cooperative metal, and bending it (unlike, for example, steel pipe) is much easier provided you use the right tools and take your time. For critical projects where bends must be precise, it’s better to use an electric/hydraulic bender with the correct die for the tube diameter to achieve a professional result.

Yes. Copper pipe is one of the best options for potable water distribution and has been used for decades in buildings for this purpose. It offers several advantages in water systems: First, unlike iron pipe, copper does not rust and exhibits low corrosion rates in typical municipal water, so the water retains its taste and color. Second, because the inner surface of copper pipe is relatively smooth and does not rust, scale build‑up is lower and pressure loss does not increase over time (in old iron pipes the internal diameter would shrink significantly after a few years due to deposits). Third, as noted, copper is antimicrobial; studies have shown that copper tubing can reduce bacteria in water (e.g., E. coli and Legionella) to some extent—an important hygiene benefit. Fourth, copper tolerates high temperatures, so in domestic hot‑water systems you can safely use water at, say, 60–70 °C without worrying about softening or deforming the pipe (unlike some polymer pipes that have temperature limits). In terms of service life, potable‑water copper pipes can operate for decades.
The main considerations are: (1) the initial cost of copper plumbing is higher than plastic systems (such as PEX or PP); (2) installing copper requires soldering/brazing skills (whereas many modern plastic systems are joined quickly by fusion or press tools). Even so, many engineers still prefer copper for its durability and long‑term reliability. In some countries, copper for potable water is regarded as a “gold standard.” Note that if the water is highly acidic (pH below 6) or contains certain salts, small amounts of copper may dissolve into the water; although copper ions at low concentrations are not harmful to humans (and copper is an essential trace nutrient), if there is concern one can use internal linings or chemical conditioning of the water.
In short: yes—copper pipe is fully suitable and reliable for drinking water, and many older copper systems remain in service without issues thanks to these positive properties.

The price is directly tied to the mass of copper contained. In Iran’s market, prices are commonly quoted per kilogram of copper, and the total order weight is the basic pricing driver. Pipe weight equals length multiplied by the weight per metre (which depends on outside diameter and wall thickness). Therefore, size (diameter and thickness) affects the price—a larger diameter or thicker wall contains more copper and costs more. The next key factor is the global copper price; copper is traded on metal exchanges (e.g., the LME) and is quoted in USD. Hence fluctuations in the global copper price and the FX rate both move local pipe prices. For example, if the LME price or the dollar rises, the price of copper pipe in local currency likewise increases.
A third factor is brand and compliance with standards: reputable brands that manufacture to standards usually price slightly above off‑brand product, reflecting the cost of quality control and certification; the gap among leading brands is not huge due to competition. The pipe type also matters: specialty products—such as medical‑grade copper requiring extra cleanliness, or inner‑grooved (rifled) tubing with more complex production—can command higher unit prices. Order quantity matters too: small retail purchases of a few lengths usually carry a higher unit price (due to cutting and retail overhead) than bulk orders. Taxes (e.g., 9% VAT) and transport are added to reach the delivered price.
Note that in day‑to‑day trading, sellers may adjust price frequently in response to copper market volatility (even daily). Some sources (industry websites or exchanges) publish up‑to‑the‑minute prices. Large buyers sometimes use forward/hedging arrangements with producers to manage price risk. In summary, the main drivers are: pipe weight and dimensions, the global copper price, FX rate, brand/quality, product type, and supply–demand conditions. When buying, obtain quotes from several reputable suppliers and choose based on these factors.

It depends on the fluid and operating temperature. Copper has high thermal conductivity; if you need to maintain temperature or limit heat exchange between the fluid and the ambient, you should insulate the pipe. Common cases: in HVAC systems, the suction line (carrying cold refrigerant) must be insulated with suitable material (e.g., elastomeric foam of adequate thickness). Otherwise it absorbs ambient heat, reducing efficiency, and causes surface condensation and dripping. Even the liquid line in split AC units is sometimes insulated in very hot climates to limit heat gain. In domestic hot‑water runs, to reduce energy loss from the plant room to points of use, both supply and return lines are insulated (with glass/mineral wool or elastomeric foam). Copper’s surface area is relatively large compared with the water volume it carries, so without insulation it gives up heat quickly to the surroundings. Conversely, for cold‑water plumbing, insulation is often applied mainly to prevent sweating in humid areas, and it also limits warming of cold water along the route. For natural‑gas plumbing, thermal insulation is generally unnecessary (temperature is near ambient), but lines may be painted or wrapped for corrosion/mechanical protection. In industrial refrigeration (e.g., ammonia lines) double‑layer insulation may be used because of very low temperatures; in petrochemical service, very hot or very cold lines are insulated for safety and efficiency.
In summary: “whenever there is a significant temperature difference between the fluid in a copper pipe and the surroundings, insulation is recommended.” Suitable materials include elastomeric foams (EPDM, NBR/PVC) and mineral or glass wool with aluminum jacketing. Thickness depends on fluid temperature and ambient conditions (e.g., 9 or 13 mm commonly used for room AC). Proper installation (tight seams and joints) is essential for performance. Copper itself does not need moisture protection, but to prevent unwanted heat transfer or condensation, insulation is necessary in many applications.

The “right” pipe depends on the project’s technical and economic constraints. Plastics (PPR, PEX, CPVC) and metals (black steel, galvanized steel, stainless) each have pros and cons. Copper combines several unique advantages that often make it the better choice: First, longevity—copper piping can deliver more than 50 years of service without performance loss, whereas the true in‑service life of some newer plastics is less established, and steel commonly has a shorter life due to corrosion. Second, strength and tolerance of harsh conditions—copper withstands higher pressure and temperature than most polymers (e.g., in hydronic heating at ~90 °C or low‑pressure steam, plastics may be unsuitable while copper works reliably). In fires, copper does not burn, whereas plastics can melt and open flow paths—dangerous in gas lines. Copper is also more resistant to impact and to rodents (which may gnaw plastics but leave copper alone). Third, hydraulics and space—copper can achieve a given flow with smaller outside diameters because of thinner walls and favorable friction factors, saving space and reducing pump head. Fourth, hygiene—as noted, copper has biocidal properties, and any copper ions that enter water are generally at very low levels and even have mild disinfecting action; by contrast, there are concerns about microplastics or additives leaching from some plastics over the long term. Fifth, O&M—a properly installed copper network can run for years without special service; if a joint leaks, a straightforward solder/braze repair usually fixes it. Some alternative systems rely on mechanical joints that may be harder to diagnose when leaking (e.g., a press fitting hidden under insulation).
Against these benefits you should weigh higher upfront material cost and the need for skilled installation. Even so, many engineers find the life‑cycle cost of copper favorable thanks to fewer repairs/replacements and long service life. Bottom line: copper is a classic, dependable choice combining strength, durability, corrosion resistance, excellent heat transfer, non‑combustibility, and hygiene—while other options may offer one or two of these, they can fall short elsewhere. Thus, although cheaper plastics can look attractive at first, in many critical, long‑term applications copper’s advantages tip the balance in its favor.
