It consists of a hydraulically tested steel cylinder with steel joint rings, centrifugally cast concrete core, high strength prestressing wire wrapped around the core and thereafter cement rich mortar coating.
Choice of Joint
The joint rings are made of thicker steel plates. The field joint can be over-lapping/sliding, butt welded or with confined rubber ring joint to suit the requirements of the client. a joint is so designed that it will be watertight under all service conditioned.
Efficient use of steel
Pre-stressed concrete cylinder pipe makes optimum use of steel. The composite action of steel cylinder , concrete core and H T wire results substantial saving of the total steel in a steel pipe as used conventionally.
