thick wall carbon steel pipe theoretical weight formula

A large diameter thick wall pipe size range

Large diameter thick wall steel pipe is usually more than the outside diameter of 325mm, wall thickness of more than 20mm steel pipe, the largest single weld diameter up to 1220mm, wall thickness up to 80mm. Double weld diameter up to 2020mm.

Second, the large diameter thick wall steel pipe uses

Large diameter thick wall pipe and more used in the construction of a large steel structure, do the main supporting part, such as a bridge piling, seabed piling, piling high-rise buildings. Its material is generally used Q345B, Q345C. The low temperature areas will also be used Q345D, Q345E.

Production of large diameter thick wall steel pipe

Production of large diameter thick wall steel pipe production methods typically include hot-rolled, hot rolled, casting! Large diameter thick wall pipe is more common in the two-sided submerged arc welding production process, the product has been bending commissure within welding outside welding, straightening, flat first class multi-process, achieve the standard requirements of the American Petroleum Institute.
