ASTM A53 Grade B seamless pipe is a carbon steel tubing widely used in structural and low/medium-pressure fluid transport systems. ASTM A53GR.B seamless steel pipe is made of high-quality carbon structural steel and undergoes strict heat treatment process. It has good corrosion resistance and can resist the erosion of acid, alkali and other chemical substances, ensuring the long-term stable operation of the pipeline system.
A53 Grade B carbon steel under the ASTM A53 specification, which covers seamless and welded black and hot-dipped galvanized steel pipes. A53 Grade B seamless steel pipe is often preferred in industries requiring robust materials, such as oil and gas, construction, and water transmission.
Conventional Dimensions:
- Outer Diameter (OD): 1/2 inch to 24 inches (seamless); up to 48 inches (welded).
- Wall Thickness: Schedule 10 to Schedule 160, including STD, XS, and XXS.
- Length: Standard lengths of 6 meters or 12 meters, with custom lengths available.
