When specifying pipe, the crush strength is a term used for pipes that experience a brittle failure. In other words, the crush strength is the load at which the pipe physically breaks. This is not applicable to a viscoelastic material such as HDPE or an elastic material such as CMP since the material will deflect under load to the point of failure. A HDPE pipe profile can actually deflect ...
