Common inspection methods:
Non-destructive testing: radiographic testing (RT), ultrasonic testing (UT), and magnetic particle testing (MT) to ensure internal and weld quality.
Hydrostatic test: Conduct hydraulic or pneumatic tests in accordance with standard requirements to verify the pressure-bearing capacity.
Mechanical property tests: tensile, impact and hardness tests.
Typical application fields:
Chemical engineering and petrochemicals: High-temperature and high-pressure reactors, distillation tower reboiler tube bundles.
Marine engineering: Seawater pumping, offshore platform pipelines.
Boilers and heat exchangers: High-temperature steam, heat carrier medium.
Food and beverage: Sterile delivery tubes, sanitary devices.
Pharmaceuticals and biology: Cleaning circulation and purification process pipelines.
