How to detect seamless steel pipe

Seamless steel pipe is a long strip of steel with a hollow section and no seams around it. The steel pipe has a hollow cross-section and is widely used as a pipeline for transporting fluids, such as pipelines for transporting oil, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, the steel pipe is lighter in weight when the bending and torsional strength is the same, and it is an economical section steel. It is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile drive shafts, bicycle frames, and steel scaffolding used in building construction. The strength and tightness of seamless pipes are stronger than that of welded steel tubes, so users will choose seamless steel pipes in many fields
