Building Astm A106 Grade B 6m Seamless Carbon Steel Pipe Hot Rolled / Cold Drawn

Building Seamless Carbon Steel Pipe , ASTM A106 Grade B Pipe Hot Rolled / Cold Drawn

ASTM A106 seamless pressure pipe (also known as ASME SA106 pipe) is commonly used in the construction of oil and gas refineries, power plants, petrochemical plants, boilers, and ships where the piping must transport fluids and gases that exhibit higher temperatures and pressure levels.

ASTM A106 Seamless Pressure Pipe (also known as ASME SA106 pipe) covers seamless carbon steel nominal wall pipe for high-temperature service. Suitable for bending, flanging and similar forming operations.

For OD>325mm, we use cold drawn method; for OD<325mm, we use hot rolled method.
