The characteristics of welded pipes mainly include the following aspects:
Flexible production process: The production process of welded pipes includes high-frequency welding, spiral welding, etc. The length can be customized according to needs, with high production efficiency and controllable cost.
Differences in mechanical properties: Welded pipes are formed by connecting the edges of the plates through welding technology, resulting in significant differences in properties between the weld area and the base metal, which can easily generate residual stresses. The bending radius usually needs to be ≥ 5D to avoid weld cracking.
Surface quality: The surface of welded pipes needs to be polished to remove excess weld height, and the surface quality of high-frequency welded pipes is better than that of spiral welded pipes.
Widely applicable scenarios: Welded pipes are suitable for general low-pressure fluid transportation, such as building water supply and drainage, HVAC, fire protection systems, etc. They are also used in the manufacturing of some structural and decorative components.
