Pipelines transport radioactive media, which have extremely high requirements on material radiation resistance, leakage prevention and long-term reliability, and need to meet strict nuclear safety standards.
Radiation Aging and Leakage Risks
Radioactive media will cause radiation embrittlement and aging of materials. Once the pipeline leaks, it will cause a serious nuclear safety accident.
Strict Zero Leakage Requirements
Once radioactive media leak, they will cause serious nuclear safety accidents and environmental hazards. The requirements for the welding quality of pipe fittings and the sealing performance of flanges meet the "zero defect" standard.
Isotope Decay and Activated Corrosion
Radioactive isotopes in the medium undergo continuous spontaneous decay, releasing high-energy rays and generating corrosive secondary products, which accelerate material embrittlement and intergranular corrosion of pipe fittings. Decay activated particles tend to deposit and adhere, causing pipeline diameter reduction and scaling blockage, while increasing radiation risks during maintenance.
