If you are looking for low carbon steel pipes that can be used in high pressure environments at high temperatures then we might have just the right solution for you. ASTM A672 Gr B70 pipe are low in carbon content and can be used under high pressure. They operate efficiently under high temperatures. ASTM A672 B70 CL 22 Pipes are electric fusion welded pipes with larger diameters. They can also be welded using most conventional methods. The diameter of these pipes ranges between 12 inches to 64 inches. However, the outer diameter of the ASTM A672 Grade B70 CL 32 EFW Pipe differs from class to class.
ASTM A672 b70 Pipe produced by us are available in different lengths single random to double random. They can also be customized in length upto 14 m. These ASTM A672 Gr.B70 Class 12 Welded Pipe offer thinner wall thickness and better workability. They are said to work at moderate temperatures. They are widely used in high temperature service. ASME SA672 Grade B70 Class 22 are delivered in normalized, annealed, or tempered condition. They are said to be durable and offer resistance at higher temperatures.
We have been producing these CS SA672 Gr B70 CL 32 EFW pipes for generations now and have evolved with time. We use ultra-modern technologies and techniques to produce these pipes and tubes. Our superior quality raw material and affordable price have made us one of the leading Carbon Steel Grade B70 Class 33 Pipe manufacturers. Our products are used in different industries in different countries across the globe.
