Product Details
The structure seamless pipes are seamless steel tubes for general structural and mechanical construction. The general-purpose seamless steel pipe is rolled from ordinary carbon structural steel, low-alloy structural steel or alloy structural steel, and has a large output, and is mainly used as a pipe or structural fitting for conveying fluid.
These structure seamless pipes are very versatile. Seamless steel pipes are mainly used as petroleum geological drilling pipes, cracking pipes for petrochemicals, boiler tubes, bearing tubes, and structural steel tubes for automobiles, tractors, and aviation. It can be widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automotive drive shafts, bicycle frames, and steel scaffolding used in construction.
