Elaborate the term - Prestressed concrete pipes

Liquid retaining structures, such as circular pipes, tanks and pressure vessels are suited for circular prestressing. The circumferential hoop compression produced in concrete by prestressing counterbalances the hoop tension developed due to the internal fluid pressure. A reinforced concrete pressure pipe requires a large amount of reinforcement to ensure low-tensile stresses resulting in a crack-free member. Circular prestressing produces the required condition of a crack-free member and the material is used more efficiently. Shrinkage cracks also are eliminated in such a situation.
