Multi Metals India is a well-known manufacturer, supplier, and distributor of ASME SA671 CS EFW Pipes in Philippines. ASTM A671 Carbon Steel EFW Tubing are commonly used for low-pressure liquid delivery and medium-pressure uses in the oil and gas industries. The EFW Tubes offers exceptional toughness, strength, resistance to corrosion, and durability. These Carbon Steel Tubing 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 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 Pipes 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 Tubing are those with the designations “CC”, meaning they have been cold-worked after welding (CW). These Pipes exhibit high 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 high 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%) 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 used for specialty applications that require high-pressure ratings or superior corrosion resistance.
