Project Description

ASTM A106 Seamless Steel Pipe

Seamless steel pipes are used in a wide range of applications, the general-purpose seamless steel pipe is rolled from ordinary carbon structural steel, low-alloy structural steel or alloy structural steel, and has the largest output, and is mainly used as a pipe or structural component for conveying fluid. Seamless steel pipes have hollow sections and are used in large quantities in transporting fluids, such as pipes for transporting petroleum, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, the steel pipe has a lighter weight but it has the same bending and torsional strength, and is an economical section steel.
