Multi Metals India is a notable manufacturer, supplier, and distributor of ASTM A671 Carbon Steel EFW Pipes in Nigeria. ASME SA671 CS EFW Tubing are commonly used for low-pressure liquid delivery and medium-pressure uses in the oil and gas industries. The EFW Tubing offers outstanding toughness, strength, corrosion resistance, and durability. These CS Pipes is made using 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, ASME SA671 CS EFW Tubes are ideal for use in extreme temperatures and difficult conditions such as acidic or chemical processing facilities where regular maintenance is essential. Furthermore, these Tubing can resist 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 ASME SA671 Carbon Steel EFW Tubes are those with the designations “CC”, meaning they have been cold-worked after welding (CW). These Tubing offer superior strength 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 offers an excellent strength-to-weight ratio, making it the most common choice for applications requiring moderate to low temperatures and pressures. The CC65 grade has a slightly higher carbon content (0.58%) as compared to CC60, 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 utilized for specialty applications that require high-pressure ratings or superior corrosion resistance.
