The simplicity of welded pipe production means high production efficiency while still allowing for various specifications to be made. However, it is less hardy as compared to seamless tubes.

The production of welded pipes involves ss coil annealing, coil slitting, TIG welding, tube cutting, deburring, polishing, QC, color plating, and packaging.

These specially-shaped tubes are widely used in structural components, tools, handrails, and mechanical parts.

Compared with stainless steel round pipes, these specially-shaped stainless steel pipes have a large cross-section modulus, better bending performance, and higher torsion resistance, resulting in a great reduction of structural weight which comparatively more cost-efficient.
