Features and specifications of PE water supply pipe production line

Pipe Introduction

HDPE large diameter gas/water supply pipes produced by HDPE large diameter gas/water supply pipe production line have excellent hardness and flexibility, heat resistance, aging resistance, high mechanical strength, environmental stress cracking resistance, creep resistance, thermal connection and other characteristics. Therefore, they have become the preferred products for suburban gas transmission and water supply pipes, and play a very important role in urban gas and water supply pipeline systems.

Features of the production line

The HDPE large-diameter gas/water supply pipe production line is a new type of pipe production line developed by absorbing the latest advanced technology. It is suitable for high-speed extrusion of raw materials such as PE, PP, PB, PERT, ABS, etc. The production line has beautiful appearance, high degree of automation and stable and reliable production. This production line is very popular among customers and is the best choice to replace advanced imported production lines.

The high-speed and high-efficiency extrusion single screw extruder is specially designed for extruding PE raw materials, equipped with a low-noise fan and a high-speed hard-toothed gearbox. The special slotted feeding sleeve with oil cooling system improves compressibility and increases filling, thereby increasing extrusion volume. The high-yield screw is specially designed, melts at low temperature, has a good plasticizing effect, and has a good energy-saving effect.

The spiral diversion extrusion die is specially designed for extruding PE raw materials. The unique low-pressure flow channel spiral or blue die design ensures the low-temperature and high-plasticization extrusion of PE pipes. The specially designed mold core spiral temperature control ensures the good performance of PE pipes; for different raw materials, the multi-layer co-extrusion die has the characteristics of low layer structure cost and low elasticity. The easy adjustment and uniform extrusion characteristics of the die ensure the uniformity of melt pressure and flow, and the uniform and smooth appearance of the pipe.

Marking line: The pipe marking line is extruded by a small single screw extruder through a composite die.

Vacuum sizing water tank: equipped with a two-stage vacuum system (for large-diameter pipes), advanced water circulation, high-pressure cooling system, vacuum adjustment device and accurate water temperature and water level automatic control system. The precise tin bronze sizing sleeve has the characteristics of fast pipe cooling and fast shaping. The material of this water tank is mainly stainless steel.

Spray cooling water tank: The long cooling system ensures efficient cooling of the pipe, and the unique pipeline system shortens the cooling length. The material of this water tank is mainly stainless steel.

Traction machine: The special integral transmission device avoids the asynchronism of independent transmission, different control methods ensure flexible and accurate positioning and orientation, and the accurate pressure regulation system can adjust the traction force. The equipment has a unique structure and flexible operability, and the frequency conversion motor can adjust the traction speed of the equipment.

Cutting machine: The fully hydraulic design of the cutting machine ensures flexible pressure during cutting, flexible adjustment of saw blade position and cutting depth. The unique power input system ensures the reliability of planetary cutting. The low-noise powerful chip suction system and the unique chip-free cutting device can ensure chip-free cutting of 16mm-315mm pipes.

Control system: The PLC control system, one of the most advanced control systems for plastic machinery, is adopted, which ensures high-quality extrusion of the equipment. The PLC control system ensures high-speed extrusion and high-precision, flexible control networking functions. Intelligent control makes the production line very easy to operate.
