Scope of application

PCCP pipes are most suitable for making large diameter pressure pipes, which can meet the requirements of urban water diversion projects, water supply systems, large sewage pipeline projects, and circulating water pipelines of large thermal power plants and nuclear power plants. There is a national standard for prestressed steel cylinder concrete pipes (GB/T19685-2005).  

① High quality new pipes with the advantages of steel pipe (SP) and concrete pipe

② The cost is lower than that of steel pipe, and the steel consumption is 70% less than that of steel pipe

③ Smooth inner wall, good hydraulic performance and convenient construction

④ The service life is more than twice that of steel pipe
