The Pinnacle of Performance – An In-Depth Analysis of Prestressed Concrete Cylinder Pipe (PCCP)

As the premier product among concrete pressure pipes, PCCP integrates the triple advantages of concrete’s compressive strength, the steel cylinder’s impermeability, and prestressing’s crack resistance. The article details its unique structure: an embedded steel cylinder serves as a perfect impermeable layer, around which high-strength prestressed wires are wound, and finally covered with a mortar protective coating. Its core performance is reflected in its extremely high pressure-bearing capacity (up to 2.0 MPa and above), exceptional sealing performance, and ultra-long design life. PCCP is the pipe material of choice for lifeline projects such as large-scale inter-regional water diversion projects, urban water supply trunk lines, and nuclear power plant circulating water systems.
