110-400mm HDPE pipe production line

Product General Information:

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.

Applications:

The pipes produced by the 400mm HDPE pipe production line belong to small and medium-sized lightweight pipes. Relying on the anti-corrosion, good flexibility, convenient connection, and low fluid resistance characteristics of HDPE material, they are widely used in urban livelihood pipeline networks, agricultural water-saving irrigation, industrial auxiliary transportation, landscaping, and temporary emergency projects. The specific application scenarios are as follows:

Urban municipal pipeline network

Residential water supply branch pipe: replacing traditional galvanized pipes and PVC pipes, used for household water supply pipelines in urban residential areas and township blocks. It is hygienic, non-toxic, and not prone to scaling, ensuring the safety of drinking water transportation; It is also suitable for the renovation of old pipeline networks, with a short construction period, which can reduce the leakage rate of the pipeline network.
Rainwater and sewage diversion branch pipe: As a rainwater collection and sewage discharge pipeline in residential and commercial areas, it is buried underground and resistant to soil corrosion. Its flexibility can adapt to ground settlement, avoid pipeline rupture and leakage, and help urban rainwater and sewage diversion renovation meet standards.

Agriculture and Rural Water Conservancy

Water saving irrigation main pipe: Suitable for irrigation systems in field planting and greenhouse fruit and vegetable bases, connecting pump stations with drip and sprinkler irrigation branches in the field to achieve efficient water supply and reduce water loss; Lightweight, easy to install, and adaptable to complex terrain in farmland.
Rural drinking water safety project: used for centralized water supply networks in villages and towns, delivering drinking water to each village group. It can be laid outdoors or underground, with strong weather resistance, solving the problem of "last mile" transportation of rural drinking water.

Industrial auxiliary conveying

Factory water supply and drainage pipelines: used for the transportation of production water in manufacturing factories, equipment circulation cooling water pipelines, and low corrosion industrial wastewater discharge. They are wear-resistant and impact resistant, suitable for complex workshop working conditions, and have low maintenance costs.
Underground pipeline in mines: As a clear water conveying pipe and wastewater discharge pipe in mines, it is lightweight and easy to transport and install in narrow underground spaces. Its corrosion resistance can extend the service life of the pipeline and reduce the investment in mine operation and maintenance.

Landscape Greening and Landscape Engineering

Greening irrigation pipe: used for irrigation systems in urban parks, green belts, and roadside trees, transporting irrigation water sources; It can also be used as a water replenishment pipeline for artificial lakes and landscape rivers, resistant to outdoor sun and rain, and not easily aged after long-term use.
Golf course sprinkler pipe: As a branch pipe of the golf course sprinkler system, it accurately delivers water to various sprinkler points, ensuring uniform irrigation of the lawn and improving the quality of landscape maintenance.
