Description:

This HDPE pipe production line is a fully automatic set of equipment that integrates raw material mixing, melt extrusion, vacuum sizing, cooling forming, servo traction, online cutting, and finished product winding/stacking. It is designed for efficient and high-quality production of high-density polyethylene (HDPE) pipes and is suitable for the manufacturing of full specification pipes ranging from 20mm to 1200mm. It can produce various types of HDPE pipes such as water supply pipes, gas pipes, sewage pipes, and steel reinforced spiral corrugated pipes.
Based on more than 20 years of experience in the research and development of extrusion equipment, the core configuration of the production line is an efficient single/twin screw extruder. The length to diameter ratio and groove structure of the screw are optimized according to the viscoelastic characteristics of HDPE materials, and a precise temperature control system is used to achieve low-temperature and efficient plasticization of materials, avoid high-temperature degradation, and ensure the toughness and pressure resistance of pipes. The host adopts variable frequency speed regulation technology, with stable and controllable extrusion volume, and a maximum extrusion efficiency of up to 1200kg/h, meeting the needs of large-scale production.
The production line adopts a composite shaping process of internal pressure sizing and spray cooling. Large diameter pipes are matched with multiple sets of crawler tractors, while small diameter pipes are adapted with roller traction and automatic winding devices. Internal pressure sizing ensures high roundness and accurate dimensional accuracy of the pipe by precisely controlling the air pressure inside the pipe, and the wall thickness tolerance can be controlled within ± 0.2mm; The segmented spray cooling system adopts a gradient cooling design, effectively eliminating internal stress in the pipes and avoiding deformation and cracking. The finished pipe ring stiffness can reach SN8-SN16, far exceeding the national standard requirements.
The entire line is equipped with a PLC intelligent integrated control system, which supports real-time monitoring, storage, and one click calling of production parameters (temperature, pressure, speed, cutting length), preset multi specification pipe production formulas, and reduces production time to within 20 minutes. Simultaneously equipped with quality monitoring modules such as online wall thickness detection and laser diameter measurement, which can automatically remove non-conforming products; The fault self diagnosis and shutdown protection function significantly reduces the cost of manual intervention and improves the safety of equipment operation.
This production line is compatible with the processing needs of HDPE pure materials, modified materials and recycled materials. The produced pipes have the advantages of corrosion resistance, aging resistance, good flexibility, convenient connection, and comply with GB/T 13663, ISO 4427 and other domestic and foreign standards. They are widely used in municipal water supply and drainage, gas transmission, agricultural irrigation, mine drainage and other fields. The equipment is exported to dozens of countries and regions around the world, and is trusted by customers at home and abroad for its stable performance and comprehensive after-sales service.
