Description

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.

The advantages of FTSSS’s welded pipes are that there are no flaws on the surfaces (i.e. dots, scratches, black lines, unevenness) as they are well polished, its welded seams are full and smooth and the pipes itself are straight with positive angles with excellent processing bending performance.

These pipes are widely used to facilitate the transfer of petroleum, chemicals, boiler gas, and can be found in plumbing devices, aerospace equipment, automobiles, food processing tools, packaging machinery, medical equipment, building decoration, furniture, railings, hardware processing equipment, shipping equipment, power plants, etc.
