Quality Control and Inspection
Non-destructive testing:
Use ultrasonic flaw detection and X-rays to detect internal defects in ring forgings to ensure that there are no hidden defects such as cracks and shrinkage holes19.
Dynamic balance and seal test:
Conduct high temperature and high pressure simulation tests on C-type sealing rings to verify their leakage rate (down to the order of Pam³/s) and resistance to irradiation to ensure no leakage during the service life.
Translated with DeepL.com (free version):
Through independent innovation, China has achieved key technological breakthroughs in the fields of sealing rings and large-sized ring components, which not only reduces its dependence on imports, but also provides Chinese solutions for the safety and sustainable development of global nuclear power. In the future, with the further optimisation of digital inspection technology and green manufacturing process, nuclear-grade rings will be developed in the direction of higher performance and lower cost.
