110-2200mm HDPE Jacket Pipe Extrusion Line for District Heating Chilled Water Pipe
This 110-2200mm HDPE Jacket Pipe Extrusion Line is a high-performance system engineered to produce durable, precision-calibrated HDPE protective casing pipes for PUR (Polyurethane) foam pre-insulated pipe systems used in district heating networks, chilled water distribution, and buried pipeline infrastructure.
Product Overview
Covering the complete 110-2200mm diameter range across 7 standard models, this HDPE jacket pipe production line serves both high-temperature district heating (up to 120°C) and low-temperature chilled water distribution applications. Featuring dust-free planetary cutting technology alongside state-of-the-art vacuum calibration forming, this system eliminates plastic dust and debris during cutting while ensuring casing pipes meet rigorous international standards including EN253, EN14241, and GB/T29047.
By integrating seamlessly into the (HDPE casing + PU foam) district heating and chilled water pre-insulated pipe manufacturing workflow, this extrusion line delivers sustained capacity of 250-1350kg/h while maintaining energy efficiency and dimensional accuracy. The resulting pre-insulated pipe casing features ±0.1mm wall thickness tolerance, smooth internal and external surfaces, superior anti-corrosion properties, and high-precision diameter accuracy.

Peak output: 1350kg/h (PE-1155/2200 model) - the highest throughput configuration for large-diameter 1155-2200mm district heating and chilled water pre-insulated pipe casing production.
All parameters are for reference only. They can be selected, matched, or modified according to customer-specific district heating and chilled water pipeline production requirements.
Production Line Composition & Process Flow
As a core component of the (HDPE casing + PU foam) district heating and chilled water pre-insulated pipe production system, this 110-2200mm HDPE jacket pipe extrusion line consists of the following key equipment (all configurations customizable):
- Vacuum Loader - automated PE granule feeding for continuous high-output district heating jacket pipe production
- Hopper Dryer - moisture removal ensuring consistent PE melt quality across the full 110-2200mm diameter range
- High-Efficiency Single Screw Extruder - high-torque output sustaining 250-1350kg/h; compatible with both virgin and recycled PE granules
- Vacuum Calibration Table - precision sizing ring system delivering ±0.1mm wall thickness tolerance and high-precision diameter accuracy
- Water Spraying Tank - multi-stage cooling ensuring structural integrity and dimensional stability
- Hauling Machine - synchronized traction for stable pipe pulling speed across all 7 diameter configurations
- Dust-Free Planetary Cutting Machine - chipless, debris-free HDPE jacket pipe cutting
- Discharging Frame - systematic pipe laying-off for storage and transport
HDPE Jacket Production Process Flow
The production process is fully automated, single-operator capable, and optimized for high-output district heating and chilled water pre-insulated pipe casing production:
- Vacuum feeding of PE granules
- Hot air drying
- Extrusion plasticizing
- Mold shaping
- Vacuum sizing/calibration (±0.1mm tolerance)
- Water spray cooling
- Synchronized hauling
- Dust-free planetary cutting
- Carrier laying-off pipe
The one-time forming process eliminates the need for edge trimming - reducing raw material waste, lowering per-unit production costs, and further improving overall extrusion efficiency.
