The welding defects of welded pipe equipment generally include cracks, overlap welding, scratches, and other issues. We have a long history and technical experience in the development and production of welded pipe equipment. Today, we will explain to you the reasons for welding defects in welded pipe equipment.

The welded pipe equipment is in good condition when leaving the factory, but cracks can appear after being flattened, straightened, or subjected to hydraulic testing by external forces.

There are many reasons for cracks in welded pipe equipment, among which the biggest influencing factors are raw materials and related process parameters. The various elements contained in the steel of welded pipe equipment have a direct impact on welding. If the carbon content inside exceeds a certain limit, brittle cracking will occur.
