Zhejiang Tank Pressure Vessel Co., Ltd. recently successfully passed the rigorous audit by Germany's TÜV and officially obtained the highest-level certification in welding system management — the EN ISO 3834-2 'Quality Requirements for Fusion Welding of Metallic Materials' system certificate.

  This certification comprehensively covers the entire range of pressure-bearing component manufacturing for the company's full product line of pressure vessels. It systematically recognizes welding processes such as manual arc welding, submerged arc welding, tungsten inert gas welding (TIG), and metal inert gas/metal active gas welding (MIG/MAG), and is compatible with various commonly used materials for pressure vessels.

  As one of the most authoritative certifications in the world's welding field, obtaining this certificate not only fully verifies that Tech has aligned with international advanced standards in welding process control, personnel skill management, non-destructive testing implementation, and full-process quality traceability. It also lays a solid quality foundation for the company to continuously expand its European and American markets for various pressure vessels, heat exchangers, and welded structural components.
