Quality Control / 质量控制
Every fitting undergoes rigorous inspection in our 1,000 m² physical & chemical testing center:
- Chemical composition analysis (PMI)
- Mechanical testing (tensile, hardness, impact)
- Hydrostatic / pneumatic pressure testing
- Dimensional inspection (ID/OD, wall thickness, angle)
- Surface & NDT inspection (RT, UT, MT, PT as required)
- Material certificates EN 10204 3.1 / 3.2
