Multi Metals India is a prominent manufacturer, supplier, and distributor of ASME SA671 Carbon Steel EFW Tubes in China. ASTM A671 CS EFW Tubing are commonly used for low-pressure liquid delivery and medium-pressure uses in the oil and gas industries. The EFW Pipes provides excellent toughness, strength, resistance to corrosion, and durability. These CS Pipes is manufactured a high-frequency electric welding process that ensures superior weld quality. It features an outer layer of protective coating to prevent corrosion from weathering elements. This also helps to extend the life of the tube and ensures it will perform reliably for years to come. Due to their robust construction, ASTM A671 CS EFW Tubing are ideal for use in extreme temperatures and difficult conditions such as acidic or chemical processing facilities where regular maintenance is vital. Furthermore, these Tubes can withstand high pressure and are resistant to extreme wear and tear, meaning they are also suitable for use in hydraulic systems and other applications requiring extensive durability.
The most popular grades of ASTM A671 Carbon Steel EFW Tubes are those with the designations “CC”, which means they have been cold-worked after welding (CW). These Tubes offer high toughness compared to hot-worked versions, making them suitable for use in various structural applications where higher pressure ratings are required. The various grades available differ by their chemical compositions, offering varying levels of corrosion resistance, temperature, and pressure ratings. The CC60 grade is an economical option that provides good weldability and formability. It features a carbon content of 0.53% and provides an exceptional strength-to-weight ratio, making it the most common choice for applications requiring medium to low temperatures and pressures. The CC65 grade has a slightly higher carbon content (0.58%) than its CC60 counterpart, which gives it high mechanical properties in elevated temperature applications such as boilers or refineries. Finally, the CC70 grade contains 0.63% carbon and is generally used for specialty applications that require high-pressure ratings or superior corrosion resistance.
