PRE-STRESSED CONCRETE CYLINDER PIPES

Pre-stressed Concrete Cylinder Pipes are rigid pipes designed to take optimum advantage of tensile strength of steel and of compressive strength and corrosion inhibiting properties of concrete. It consists of a concrete lined steel cylinder with steel joint rings welded to its ends wrapped with a helix of highly stressed wire and coated with dense cement mortar or concrete. It has been extensively used for years for such applications as water transmissions and distribution pipelines, sewer force mains, cooling water systems and liners for pressure 2 tunnels. They are well suited for working pressures as high as 20kg/c
