The pipes produced by the HDPE large-diameter water supply pipe production line have moderate rigidity and strength, good flexibility, creep resistance, environmental stress cracking resistance and good thermal welding performance. They have become common products for urban gas transmission pipelines and outdoor water supply pipes.

HDPE, MDPE water supply pipes and gas pipelines have good flexibility, rigidity, creep resistance, environmental stress cracking resistance and good hot melt welding properties.

The HDPE, MDPE water supply pipe and gas pipe extrusion production line independently developed by our company has a high degree of automation, convenient operation, and very stable continuous extrusion production. The production line consists of an extruder, a die, a shaping cooling system, a haul-off machine, a cutting machine, a material turning rack, a control system, etc., and is equipped with a marking line extruder. The extruder adopts a high-efficiency screw and a strong conveying bushing. The die adopts a spiral structure, the material is discharged evenly, and the static mixing eliminates the seam line. The entire production line can achieve monotonous and unified control, and the operation is very convenient. The HDPE/MDPE water supply pipe and gas pipe production line independently developed by our company has a unique structure, a high degree of automation, convenient operation, and stable and reliable continuous production. Composition: The production line consists of a control system, an extruder, a die, a shaping cooling system, a haul-off machine, a planetary cutting device and a material turning rack. Molds and auxiliary machines: The die adopts a newly designed basket die or a spiral split-flow extrusion composite die, which is easy to adjust and has the characteristics of uniform discharge. The sizing sleeve adopts a unique slotting process and water ring cooling to ensure the forming accuracy of the pipe. The control system is composed of advanced PLC and large-screen color LCD, with a complete alarm system and good Chinese human-machine interface, which is very convenient to operate.
