With more than 40 years of proven performance, PEX is a piping solution receiving broader industry acceptance with more engineers specifying and designing with the material. However, one criticism from skeptical engineers relates to the pipe’s expansion characteristics.
There is a misconception that all PEX pipe sizes expand and contract at the same rate, both horizontally and vertically. The fact of the matter is…PEX expansion in vertical riser applications with proper clamping and support has not been well documented to date.
To challenge this misconception, a team at Fleming College in Ontario set up a riser simulation. The testing revealed that as PEX pipe sizes increase, they behave more like their copper counterparts in displacement and deflection.
