Multi Metals India is a notable manufacturer, supplier, and distributor of ASTM A671 Carbon Steel EFW Tubing in Romania. ASTM A671 CS EFW Tubing are commonly used for low-pressure liquid delivery and medium-pressure applications in the oil and gas industries. The EFW Tubing 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 pipe 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 Pipes 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 CS EFW Pipes are those with the designations “CC”, meaning they have been cold-worked after welding (CW). These Tubes offer superior 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 choice that offers high weldability and formability. It features a carbon content of 0.53% and offers an excellent strength-to-weight ratio, making it the most common option for applications requiring moderate to low temperatures and pressures. The CC65 grade has a slightly higher carbon content (0.58%) than its CC60 counterpart, which gives it better mechanical properties in high 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.
