Automatic Large Diameter HDPE Jacket Pipe Production Line for Thermal Insulation

Automatic Large Diameter HDPE Jacket Pipe Production Line for Thermal Insulation Pipe

1. Product Overview

The HDPE Jacket Casing Pipe Extrusion Line is a high-performance system engineered to produce durable protective casings for PUR (Polyurethane) foam pre-insulated pipes. Utilizing state-of-the-art vacuum calibration technology, this production line ensures that casing pipes meet rigorous international standards for thermal insulation and mechanical protection.

By integrating seamlessly into the (HDPE casing + PU foam) manufacturing workflow, our equipment delivers high-speed output while maintaining energy efficiency. The resulting pipes feature superior anti-corrosion properties and high-precision diameter accuracy, essential for long-term underground and industrial service.

3. Production Line Composition & Process Flow

3.1 Key Equipment Configuration

As a core part of the (HDPE casing + PU foam) pre-insulated pipe production line, this HDPE extrusion line consists of the following key equipment (configurations can be customized):

• 1 set of Vacuum Loader
• 1 set of Hopper Dryer
• 1 set of High-efficiency Single Screw Extruder
• 1 set of Vacuum Calibration Table
• 1 set of Water Spraying Tank
• 1 set of Hauling Machine
• 1 set of Cutting Machine
• 1 set of Discharging Frame

All equipment operates in perfect coordination to ensure stable, efficient production of high-quality HDPE casing pipes, matching the overall operation efficiency of the (HDPE casing + PU foam) pre-insulated pipe production system.

3.2 HDPE Jacket Production Process Flow

The production process is fully automated, simple to operate, and efficient, with the following steps:

Vacuum feeding of PE granules → Hot air drying of material → Extrusion plasticizing → Mold shaping → Vacuum sizing → Water cooling → Pulling out → Cutting pipe → Carrier laying-off pipe

The one-time forming process eliminates the need for edge trimming, reducing raw material waste and further improving production efficiency.
