Seamless Steel Tube: Seamless steel tube is a round, square, rectangular steel with a hollow section and no joints around it. Seamless steel tubes are made by punching steel ingots or solid billets and then hot rolled, cold rolled or cold drawn. Seamless steel tubes have a hollow cross-section and are used in a large number as pipes for conveying fluids. Compared with solid steel such as round steel, steel pipes have a lighter weight when subjected to the same flexural and torsional strength. They are economical cross-section steels and widely used in the manufacture of structures. Parts and mechanical parts, such as oil drill pipes, automobile drive shafts, bicycle racks, and steel scaffolding used in construction.
Welded pipe: Welded steel pipe, also called welded pipe, is a steel pipe made by welding a steel plate or strip after crimping. Welded steel pipe production process is simple, high production efficiency, variety specifications, equipment and less, but the general strength is lower than the seamless steel pipe.
Trading steel pipes, seamless steel pipes, alloy steel pipes, stainless steel pipes, etc., or 51 steel pipe network -.
Seamless steel pipe and welded pipe are mainly different from the molding process. Ordinary steel pipes, such as tap water pipes, are generally welded by bending the flat sheet material. You can find a weld on the surface. The thicker ones are generally spiral welds. The seamless steel pipe is generally formed by the molten steel in a molten state being accumulated in a ring-shaped slit and then processed by a drawing process. Thus, there is no weld seam. In terms of performance, especially the pressure capacity is greatly improved compared to ordinary steel pipe, so it is often used in high-pressure equipment. Such as hydraulic equipment, such as pipeline connections. The weld part of the ordinary steel pipe is its weak link, and the weld quality is also the main factor affecting its overall performance. People who have lived in the north have generally had the experience of tapping water pipes or heating pipes in the winter. The places where the explosions occur are generally welded seams. Welded pipes are not seamless steel pipes.
