Information from the American Concrete Pipe Association: "Concrete or HDPE: Strength versus StiffnessThe primary difference between concrete pipe and high density polyethylene pipe (HDPE) is one of structural strength versus pipe stiffness. These terms are not interchangeable: the differences between them are significant and technical in nature. Concrete pipe is a rigid pipe that has significant structural strength. This is best demonstrated through the traditional method for measuring pipe strength, the three-edge-bearing test. Easily the most severe loading to which any pipe will be subjected, the three-edge-bearing test allows no lateral support for the pipe and applies forces that are virtually point loads. The load carrying capacity of this rigid pipe when installed is increased by at least two-fold because of active soil pressure." Read more... "Handling & Installation ComparisonsManufacturers of high density polyethylene pipe (HDPE) claim that the longer lengths, lighter weights and fewer joints of their products yield substantial cost savings. This claim, however, is difficult to prove using actual field data. In some cases, the very attributes of concrete pipe that competitors cite as disadvantages prove beneficial to the installation and performance system."Durability: Too Important to IgnoreOne of the most critical but overlooked factors in project design is material durability, or service life. Even such fundamental considerations as a material's ability to perform intended structural and hydraulic functions become irrelevant if a pipe cannot perform satisfactorily for an economically acceptable period."
