Equipped with automatic ring welding machines, semi-automatic wave expansion, bending, flaring, and straightening machines. We ensure accurate custom sizing and 100% pressure testing (8kg for 15s) to guarantee zero leakage and no porosity.
Sourcing from top-tier suppliers like POSCO and TISCO. All pipes undergo integral solid solution treatment. We strictly control OD tolerance and weld residual height to eliminate internal weld traps. Each piece passes a 15kg pressure test for 15 seconds.
(A) Bending Test | (B) Flattening Test | (C) Flaring Test
Specializing in Argon arc and Plasma welding. Online annealing is utilized to reduce hardness, improve elongation, and prevent cracking during subsequent bending or heat treatment.
