OVERVIEW Erie County is home to nearly 1 million people in western New York.The Buffalo-Niagra metropolitan area is the second largest region in the state. In the 1970s, 30” prestressed concrete cylinder pipe (PCCP) manufactured by Interpace was installed near an electric grid system. During this time Interpace PCCP included defective materials and poor practices. […]
Read this case study and learn how Thompson Pipe Group protects steel components in concrete pressure pipe joints with three layers of exterior protection: zinc metallized coating, cement mortar and Typar/Ethafoam.
PCCP Case Study: Explosive Myths Busted Pre-stressed concrete cylinder pipe safe for tapping and more Overview Prestressed concrete cylinder pipe (AWWA C301) gets a bad rap. Despite rumors and outdated information, the pipe is in service in all 50 states. First installed after World War II, PCCP is one of the most rigid and long-lasting […]
PROJECT OVERVIEW Not long after acquiring Detroit Water, the Great Lakes Water Authority required 3-miles of pipe to meet the suburban sprawl demand. The entity specified 48” steel and prestressed concrete cylinder pipe (PCCP). PCCP is a rigid pipe, installation moves quickly. Harness clamps speed up installation time and reduce costs. The two-clamp mechanically restrained […]
Concrete pressure pipe combines the tensile strength of steel with the compressive strength and corrosion-inhibiting properties of Portland cement concrete and mortar. The stiffest and strongest of the commonly specified semirigid water pipes, C303 bar-wrapped pipe is manufactured using a welded steel cylinder with sized, welded-steel joint rings attached. The steel cylinder is lined with […]
