Multi Metals India is a prominent manufacturer, supplier, and distributor of ASTM A671 Carbon Steel EFW Tubing in Brazil. 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 Tubes offers outstanding toughness, strength, corrosion resistance, and durability. These Carbon Steel Tubes 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 pipe and ensures it will perform reliably for years to come. Due to their robust construction, ASME SA671 Carbon Steel EFW Tubes are ideal for use in extreme temperatures and difficult environments such as acidic or chemical processing facilities where regular maintenance is essential. Additionally, these Tubing 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 CS EFW Tubing are those with the designations “CC”, which means they have been cold-worked after welding (CW). These Tubing exhibit high strength compared to hot-worked versions, making them ideal 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 choice that provides high weldability and formability. It contains 0.53% carbon and offers 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.
