What is Concrete Pressure Pipe (CPP)
Concrete Pressure Pipe: A Robust Solution combing concrete and steel for Conveying Liquids with High Resistance to External Loads and Internal Pressures.
The More You Know about Concrete Pressure Pipe, the More You’ll Insist on It
A concrete pressure pipe is a specially designed item that brings together the advantageous properties of Portland cement concrete and steel, forming a sturdy structure for transporting liquids under varying external stress and internal pressure conditions.

Types of CPP
The American Water Works Association (AWWA) defines four types of concrete pressure pipe:
Reinforced Concrete Pressure Pipe, Steel-Cylinder Type
(AWWA C300)
C300 utilizes a steel cylinder and steel rebar cages in the pipe design. It is available from 30in (750mm) diameter and up and is typically limited to a maximum working pressure of 260psi (1790kPa).
Prestressed Concrete Pressure Pipe, Steel-Cylinder Type
(AWWA C301)
There are two types of C301 pipe, Lined-Cylinder Pipe (LCP) and Embedded-Cylinder Pipe (ECP), both of which utilize a steel cylinder and pre-stress wire.
LCP is available up to a maximum of 60in (1500mm) diameter, while ECP is most commonly available from 48in (1200mm) and up.
Reinforced Concrete Pressure Pipe, Noncylinder Type
(AWWA C302)
C302 utilizes steel rebar cages and can have either steel or concrete joint rings. It is commonly available from 24in (600mm) to 144in (3660mm) and limited to a maximum working pressure of 55psi (380kPa).
Concrete Pressure Pipe, Bar- Wrapped, Steel-Cylinder Type
(AWWA C303)
First offered in the early 1940’s, it is similar to C301 pipe but utilizes rebar in place of pre-stress wire and is classified as a semi-rigid pipe. C303 is commonly available from 14in (350mm) to 64in (1600mm).
