Prestressed Concrete Pressure Pipe (PCCP), Steel-cylinder Type
Embedded-cylinder Pipe (ECP). First installed in North America in 1953, ECP consists of a welded steel cylinder with steel joint rings at each end and embedded in a concrete core, high-tensile strength steel wire wrapped on the exterior concrete core surface and an external coating of Portland cement mortar.

The prestressing wire in lined cylinder pipe is wrapped directly around the steel cylinder. A second type of PCCP was developed in 1952 that has concrete encasement of the steel cylinder on both sides. Known as embedded cylinder pipe, it differs from lined cylinder pipe by the encapsulation of its steel cylinder in a concrete core.
Prestressed Concrete Cylinder Pipe; Embedded Type (AWWA …
Prestressed Concrete Cylinder Pipe (PCCP; embedded) combines concrete’s high compressive strength to form durable structures that can stand up to any water and/or wastewater project requirements. PCCP (C301E) is manufactured in accordance with the AWWA C301 standard and is designed in accordance with the AWWA C304 standard.
There are two types of prestressed concrete steel-cylinder pipe: (1) the lined-cylinder type, with a core composed of a steel cylinder lined with concrete and subsequently wire-wrapped directly on the steel cylinder and coated with mortar; and (2) the embedded-cylinder type, with a core composed of a steel cylinder
Structural performance of buried prestressed concrete cylinder pipes ...
2016年1月1日 · Prestressed concrete cylinder pipe (PCCP) originally appeared in 1942 as Lined Cylinder Pipe (LCP). After a decade, Embedded Cylinder Pipe (ECP) was developed as another type of PCCP with concrete encasement of the steel cylinder on both sides and prestressing wire wrapped around the outer concrete core.
Calculation model for bar-wrapping during prestressing of an embedded …
2019年6月1日 · From two-dimensional to three-dimensional, based on the elastic foundation beam theory, a calculation model for bar-wrapping during prestressing is proposed and used in an embedded bar-wrapped cylinder concrete pressure pipe with an inner diameter of 1400 mm. A field experiment was designed to validate the model.
