Hdpe pipe buckling
Webα = thermal expansion coefficient, in/in/°F. ΔT = temperature change, °F. The coefficient of thermal expansion for DriscoPlex® high density polyethylene pipe material is about 9.0 x 10-5 in/in/°F. This coefficient results in an approximate expansion for pipe of 1/10/100, that is, 1 in for each 10° F change for each 100 ft of pipe. WebJun 3, 2001 · Buckling of two groups of samples—each consisting of 20 steel pipes lined with HDPE liners—was examined in the laboratory. Group A was subjected to a uniform external pressure equal to about one-half of the buckling pressure, determined experimentally in a similar short-term test.
