We provide complete range of Prestressing Systems and Construction Engineering Techniques for various circular structures such as Silos, LNG Tanks and Nuclear Containment Structures etc.
Liquid retaining structures, such as circular pipes, tanks and pressure vessels are also admirably suited for circular prestressing. The circumferential hoop compression induced 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 structure. However, circular prestressing eliminates cracks and provides for an economical use of materials. In addition, prestressing safeguards against shrinkage cracks in liquid retaining structures. Circular prestressing is also applied in domes and shells.
