Field test of Glass fiber reinforced polyethylene pipe system at soften ground

Papers # 2018 Las-Vegas

Glass fiber reinforced polyethylene pipes and fittings are controlled for bending characteristics (Strength and stiffness) for vertical and axial directions of pipe by spiral cross winding method. Generally, to use this method, it takes much stronger for vertical strength than axials cause of extruded direction, besides it’s more stable of ovality for large diameter pipes. It is expected to use pressure pipes for large diameter pipeline with thermoplastic welding method easier. 

Here is shown the experience of field test for soften ground located in Hokkaido ,Japan used 600mm DN/ID (SIDR35), total length is 33mm with electrofusion and butt welding joint. These pipes and joints indicate to keep the shape of pipe by the cross section against to adjust for axial followed behavior on the soften ground.
