Embedded Type E-301

Prestressed Embedded Pipe is excellent for applications such as distribution and transmission mains, treatment plants and industrial piping. Pre-stressed Concrete Embedded pipe combines concrete’s high compressive strength to form durable structures that can stand up to project requirements.

There are many major benefits achieved by using PCCP. The source of all these benefits is the pipe’s unique design concept, featuring steel cylinder encased in rugged prestressed concrete. The mortar coating on the pipe creates a passivating alkaline environment that protects the steel cylinder, joint rings and pre-stressing wire from corrosion. Since concrete continues to gain strength while underground, the materials in PCCP will be increasingly protected over many decades of service.

Often, when service taps are made on the PCCP water lines, an inspection is made of the section of pipe wall that is cut out and replaced by the tap. Such inspections—even on pipe that’s been in continual service for 50 years or more—invariably show no signs of deterioration of either the concrete or steel components. The many built-in features of PCCP assure power plant owners decades of trouble-free service.
