Carbon Square Steel Pipe Bar Rectangular ASTM G3466 Metallurgy Industry

Steel pipes have hollow sections that are much longer than the diameter or circumference of steel. According to the cross-sectional shape, it is divided into circular, square, rectangular and special-shaped steel pipes;  according to the material, it is divided into carbon structural steel pipes, low-alloy structural steel pipes, alloy steel pipes and composite steel pipes;  Steel pipes for thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, high-pressure equipment, etc.;  according to the production process, they are divided into seamless steel pipes and welded steel pipes, of which seamless steel pipes are divided into hot-rolled and cold-rolled (drawn) Two types, welded steel pipes are divided into straight seam welded steel pipes and spiral seam welded steel pipes.

Welded steel pipe, also known as welded pipe, is a steel pipe made of steel plate or strip steel after crimping and welding. Large-diameter or thicker welded pipes are generally made of steel billets directly, while small welded pipes and thin-walled welded pipes are generally made of steel strips directly welded. The production process of welded steel pipe is simple, the production efficiency is high, and there are many varieties and specifications.
