Many tanker failures stem not from purchased spare parts but from tank welding defects and sealing failure. Welding work and pressure‑based sealing testing are two critical procedures determining service life and safety performance.
Welding: seams for tank shell joints and internal bulkheads are high‑risk zones. Qualified factories adopt submerged‑arc welding or gas‑shielded welding, followed by visual inspection and non‑destructive testing for key welds. Porosity or slag inclusions inside welds lead to crack propagation under long‑term road vibration and cause cargo leakage.
Pressure‑sealing test: after tank welding completion, hydrostatic or pneumatic tightness test simulates real working pressure to check leaks on weld seams, manholes and valve flanges. Vehicles shall not be painted and delivered without finishing this test.
Many low‑cost products skip non‑destructive inspection or simplify pressure tests. No obvious defects appear in early stage, yet leakage emerges months after operation with expensive repair costs. Buyers can request welding specifications and tank pressure‑test reports from manufacturers.
Every tanker from Jining Yangming Heavy Industry goes through full weld inspection and tank pressure tightness test with archived records, to guarantee safe and durable deliveries.
Yangming Heavy Industry focuses on the manufacturing of specialized vehicles and trailers, providing one-stop procurement experience for overseas customers from product selection to after-sales support.
