How to distinguish between seamless steel pipe and ordinary steel pipe? 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. Shandong Seamless Steel Tube Factory () is a company that specializes in seamless steel pipe production, processing and sales.
