We knew that pipes are used to transport gas or liquid substance from one place to another place.
Different types of pipes such as steel pipe, PVC, uPVC, and RCC pipes are used in water transportation and PSC (Prestressed Concrete Pipe) pipe is one among them. The selection of pipe is based on the purpose, location, workability, and required durability.
The prestressed concrete pipes (PSC) usage evolved in recent years and replaced the conventional pipes such as RCC pipe, Steel pipe based on both strength and cost.
Prestressed Concrete Pipes are commonly used large diameter pipe manufactured by concrete and the high tensile steel wire which is helically placed around the concrete core under specific tension that gives tensile strength to the pipe.
The concrete is strong against compression force and weak against tension force so steel is placed around the concrete core to make it strong against both compression and tension force.
The grade of concrete depends on the strength required for the specific work and M15 is the minimum grade of concrete used for manufacturing the reinforced concrete pipe.
The prestressed concrete pipes are classified as mentioned below.
In this type, a helix of high tension prestressed steel wire placed around the concrete core, and a certain thickness of cement mortar placed to cover the steel wire. The steel joint rings are provided at both ends of the pipe for connecting to other pipes.
In this type, a helix of high tension prestressed steel wire is placed around the concrete core by both longitudinal and circumferential directions, and the cement mortar coat placed over the wire wrap for protection.
The manufacturing specification of prestressed concrete pipe has been mentioned in IS code 784. The selection of the right material for manufacturing and quality, strength testing method also specified in that.
The PSC pipes are majorly used for water transportation systems where high pressure of water is supplied.
