Deflection occurs in pipes, mainly construction pipes, that are under a lot of pressure. The most common situation is when a flexible pipe, such as a polymer or plastic-type, bends too far out of its shape to be useful or safe. The accepted flexibility for pipes that are not rigid is 2%, meaning anymore and it is prone to break down or otherwise be unusable. Flexible pipes are made of different materials than rigid pipes, which leads to another set of problems.
Pipes under pressure gradually bend into an oval shape. How distorted the oval shape is can be detected by measuring the ring or change in diameter. This often happens within the first couple months of a pipe being underground, but can sometimes occur later on as time goes by. Often, a pipe will change shape multiple times before settling into one form. Therefore, it is … Read More
