Welded pipe, also known as welded steel pipe, is a welded pipe products.The following is a detailed introduction to the welded pipe:
First, the definition and production process Welded pipe is made of steel plate or strip steel after roll forming and welding of steel pipe.Its production process usually includes forming, welding, finishing three basic processes.Specifically, first of all, hot-rolled or cold-rolled strip as raw material, the strip will be bent into a tube with a straight or spiral seam; then, with different heat sources to heat the edges of the seams, through the pressure welding or welding to get a certain strength of the weld; finally, and then by the calibrating, cutting, straightening, heat treatment, hydrostatic testing and plating and other processes to make the finished tube.

1. process and high production efficiency: The production process of welded pipes is relatively simple, enabling rapid production of large quantities of steel pipes.
2. Wide range of specifications: Welded pipes can be customized according to user needs, with options for length, diameter, thickness, and other parameters.
3. Lower equipment investment: Compared to seamless steel pipes, the production equipment for welded pipes requires less investment.
4. Extensive application fields: Welded pipes are widely used in various fields such as water supply engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, and urban construction, for the transportation of liquids, gases, or solids, as well as for the manufacture of furniture, lighting, and other products.
