Product Technical Faqs From Advanced Drainage Systems
A hdpe pipe profile can actually deflect until the material is flattened due to reverse curvature therefore an analogous test to crush strength for hdpe pipes would be aashtos pipe flattening test which requires the pipe be deflected 20 with no signs of wall buckling cracking splitting or delamination at a specified pipe stiffness
