Evaluation of the Mechanical Behavior of Plain and Spirally Stiffened Polyvinyl Chloride Pipes
The evaluation of the merits of spirally stiffened polyvinyl chloride pipes over the merits of conventional plain (unstiffened) pipes is achieved experimentally. Various relevant standard tests have been performed on both types of pipes made of the same material. These tests are bursting, impact resistance and short- and long-term stiffness tests. The experimental results are compared favorably with appropriate formulae found in the literature. It is concluded that considerable saving in material could be realized with no significant loss in pipe stiffness or impact resistance by adopting a spirally stiffened pipe design rather than a plain design.
