Abstract:
High Density Polyethylene (HDPE) Pipes are manufactured all over the
world by extrusion technique. Sizing methods still vary but the trend is
the pressure sizing i.e. introducing air at the pressure of about 0.8
kg/cm2 to 1 kg/cm2 through one of the spider legs of the dies. HDPE
Pipes are generally manufactured on single screw extruder.
