Large Diameter HDPE Pipe Extrusion Machine for Water Mains with Helical Die

The 710–1600mm HDPE Pipe Extrusion Line for Water & Gas Mains with Helical Die by Qingdao Huashida Machinery is a heavy-duty, high-output solution engineered for the production of large diameter PE80 and PE100 water main and gas main pressure pipes from Ø710mm to Ø1600mm, with peak output reaching 2000–2500 kg/h on the flagship SPEG-2200 model. Built for pipe factories, municipal engineering suppliers, and international EPC contractors, this large diameter HDPE pipe extrusion line produces thick-wall pipes that maintain their size, roundness, and pressure rating across long production runs.

By integrating an SJ150×33 38CrMoAlA nitrided alloy single screw extruder, an advanced helical basket die head, a stainless steel vacuum calibration tank, and a chipless planetary cutting system, this line ensures ±0.1mm diameter accuracy, uniform wall thickness, and strong PE100 pipe hoop strength for underground water main and gas main pipelines. The PLC full-touch control system keeps every stage synchronized, and Bureau Veritas (BV) audited supplier status gives procurement teams independently verified factory credentials.

Our PE Pipe Production Machinery comes in various configurations to meet diverse output requirements.

This 710–1600mm HDPE Pipe Extrusion Line serves large-scale pipeline sectors globally:

• Water Main Transmission: Large diameter PE100 water supply and trunk main pipe for city-scale distribution networks in the Middle East, Central Asia, Africa, and Europe.
• Gas Main Distribution: Thick-wall PE100 gas main pipe for urban natural gas networks that require consistent wall thickness and hoop strength.
• Energy and Mining: Landfill leachate collection, industrial chemical transport, and high-pressure energy conduits using durable PE100 polyethylene pressure pipe.
• Geothermal and Irrigation: Large diameter geothermal heating and agricultural irrigation mains that demand long service life.

1. Automatic Feeding & Drying: Vacuum automatic loader and hopper dryer remove moisture from PE80/PE100 resin, avoiding bubble defects in large diameter HDPE pipe extrusion.
2. High-Torque Uniform Extrusion: SJ150×33 38CrMoAlA nitrided single screw extruder with a high-torque drive ensures uniform plasticization and stable melt pressure for PE100 water main and gas main pipes.
3. Helical Basket Die Head Forming: The low-temperature helical basket die head delivers uniform melt mixing, improving roundness, wall thickness consistency, and hoop strength of thick-wall pipes.
4. Precision Vacuum Calibration: Stainless steel vacuum calibration tank with water film lubrication and sizing rings ensures ±0.1mm diameter accuracy on heavy large diameter pipes.
5. Multi-Stage Spray Cooling: Gradient water spray cooling prevents deformation and builds the structural toughness of finished HDPE water & gas main pipes.
6. Chipless Planetary Cutting: Heavy-duty synchronous haul-off with chipless planetary cutting delivers dust-free, flat, burr-free cuts that meet environmental production standards.
7. Co-Extrusion Marking & Automatic Stacking: 25/25 color strip co-extrusion marks water and gas pipe identification lines, and the automatic pipe stacker supports continuous large diameter pipe production.
