What is the difference between seamless steel pipe and welded pipe?

Answer:

The main molding process is different. Ordinary steel pipes, such as tap water pipes, are usually welded by bending flat plates, and you can find a seam on it;
Such as hydraulic equipment pipeline connection. The weld seam of common steel pipe is its weak link, and the quality of weld is the main factor that affects its overall performance. People who have lived in the north have experienced the experience of freezing pipes and pipes in winter, and the places where they burst are usually welds. Welded pipe is not seamless steel pipe.
The thicker the diameter, the more commonly the spiral weld. The seamless steel pipe is generally molten state molten steel through the annular slot backlog, and then stretched and other treatment process, so that there is no weld. On the performance, especially the pressure capacity of the steel pipe than ordinary steel has greatly improved, so often used for high voltage equipment.
