• Low coefficient of friction means HDPE is very “slick.” This makes it easy for fittings to rotate on the pipe or migrate along it. • Toe-in occurs when HDPE is cut. This can affect tapping sleeves and saddles, and makes stiffeners difficult to install in pipe ends. HDPE has a lower modulus of elasticity and higher coefficient of thermal expansion than other pipe materials.
