Seamless steel pipe is a long strip of steel with a hollow cross-section and no seams around it. It is widely used in the manufacturing of structural components and mechanical parts, such as oil drill rods, automotive transmission shafts, bicycle frames, and steel scaffolding used in construction. Using steel pipes to manufacture circular parts can improve material utilization, simplify manufacturing processes, save materials and processing time, such as rolling bearing rings, jack sleeves, etc. Currently, steel pipes are widely used for manufacturing. Steel pipes are still an indispensable material for various conventional weapons, such as gun barrels and cannon barrels, which require steel pipes for manufacturing.
Welded steel pipe, also known as welded pipe, is divided into straight seam welded pipe and spiral welded pipe. It is a steel pipe made by welding steel plates or steel strips after curling and forming. The production process of welded steel pipes is simple, the production efficiency is high, there are many varieties and specifications, and the equipment resources are limited, but the strength is generally lower than that of seamless steel pipes. The applications include: low-pressure fluid transport pipes, ordinary carbon steel wire sleeves, straight seam welded steel pipes, galvanized welded steel pipes for low-pressure fluid transport, spiral seam submerged arc welded pipes for pressurized fluid transport, spiral seam high-frequency welded steel pipes for pressurized fluid transport, spiral seam submerged arc welded steel pipes for general low-pressure fluid transport, and spiral welded steel pipes for piles.
