Welding quality determines the safe service life of a tank truck.
Automated Welding: Utilizing plasma longitudinal seam welding and automated submerged arc welding technologies, we ensure deep weld penetration, uniformity, and freedom from porosity. Non-Destructive Testing (NDT): Every pressure vessel must successfully pass X-ray flaw detection prior to delivery.
Performance Assurance: Rigorous testing ensures that the tank body remains free of any deformation—even when subjected to 1.5 times its design pressure—thereby completely eliminating the risk of cracking during long-distance overseas transport.
