Technical Prameters:

HDPE Jacket Process Flow:

1. Vacuum Feeding of PE Granules: The raw PE granules are automatically fed into the system via vacuum suction.
2. Hot Air Drying: The granules are dried using hot air to remove moisture, ensuring optimal extrusion quality.
3. Extrusion Plasticizing: The dried granules are plasticized through the extruder, heated and mixed to form a molten plastic mass.
4. Mold Shaping: The molten plastic is shaped into the desired pipe profile by passing through the extrusion die.
5. Vacuum Sizing: The pipe is then subjected to vacuum sizing, adjusting its dimensions to precise specifications.
6. Water Cooling: The pipe is cooled rapidly by immersion in a water tank to solidify its shape and structure.
7. Pulling Out: The solidified pipe is pulled out of the cooling tank at a controlled speed.
8. Cutting: The pipe is cut to the desired length using a precision cutting machine.
9. Carrier Laying-off: The cut pipes are then neatly laid off onto a carrier for further handling or packaging

gas/oil /water pipeline Puf Pre-Insulated Pipe PE shell casing plastic Machinery Advantages:The inclusion of PUF (Polyurethane Foam) 

1. Reduced Heat Losses:
   • By effectively insulating the pipeline, PUF insulation minimizes heat losses to as low as 8%, significantly outperforming traditional insulation methods that often suffer from heat losses of 30-40%. This enhanced thermal efficiency leads to lower energy consumption and reduced operating costs.
2. Capital Cost Savings:
   • The cost-effectiveness of PUF insulation is further evident in the reduction of capital costs by 15-20%. This is primarily due to the elimination of the need for concrete channels and chambers for valves, which are often required in traditional pipeline systems.
3. Reduced Operating Costs:
   • The improved thermal efficiency and reduced heat losses lead to a significant reduction in operating costs. Specifically, the use of PUF insulation can result in operating cost savings of up to 9 times compared to traditional systems.
4. Lower Repair Costs:
   • The durability and resilience of PUF insulation reduce the frequency and severity of repairs, leading to a 3-fold decrease in repair costs. This not only saves money but also minimizes the inconvenience and downtime associated with repairs.
