The maximum pipe diameter depends on the model and configuration of the HDPE pipe machine. The extruder size, die head, cooling tank, haul-off unit and other downstream equipment must match the required pipe diameter. A properly configured HDPE pipe making machine can produce pipes from small sizes to large-diameter pipes for water supply, irrigation, drainage and industrial applications. Before selecting an HDPE pipe extrusion machine, buyers should confirm their required diameter range, wall thickness, pressure rating and production capacity.
