GB/T 28725-2012
ActiveCathodic protection for buried prestressed concrete cylinder pipelines
埋地预应力钢筒混凝土管道的阴极保护
Application Summary AI generated
This standard specifies the technical requirements for applying cathodic protection to buried prestressed concrete cylinder pipelines (PCCPs) to prevent corrosion of the steel cylinder and prestressing wires. It is applied in the water supply, wastewater, and industrial pipeline industries, specifically during the design, installation, and maintenance of underground PCCP systems. The standard ensures long-term structural integrity and operational safety by mitigating electrochemical corrosion in aggressive soil environments.
