1) Advanced Manufacturing Facility: Equipped with automatic ring welding machines, semi-automatic wave expansion machines, bending, flaring, and straightening equipment. We ensure 100% pressure tests (8kg for 15s) to guarantee zero leakage and no porosity.
2) Strict Process Requirements: Raw materials are sourced from top-tier suppliers like POSCO and TISCO. Pipes undergo integral solid solution treatment. We strictly control OD tolerance and weld residual height to eliminate internal weld traps.






Space-Saving Packaging: We utilize professional techniques like inserting smaller tubes into larger tubes to maximize container space and reduce freight costs for our customers.
