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

PU Foaming Pre-insulated Pipe Production process Flow:

The production process of "pipe in pipe" (PU Foaming Pre-insulated Pipe) mainly includes three steps: surface pretreatment of steel pipe, production of HDPE outer protective pipe and production of insulation layer.

The production steps of insulation layer are as follows: firstly, the steel pipe is penetrated into the high-density polyethylene outer protection pipe to form a casing structure, and the supports are evenly arranged in the annular space between the steel pipe and the high-density polyethylene outer protection pipe, and the two ends are sealed by flanges; secondly, the casing is hoisted on the foaming platform, and the polyurethane foaming material is injected into the casing by high-pressure foaming machine; finally, the polyurethane material is foamed After curing, the sealing structure at both ends is removed to complete the production process of the insulation layer.

Rigidity due to the presence of strong ties between the steel pipe layer polyurethane insulation and jacket pipe and provides pre-shot blast or blast cleaning the surface of the steel pipe, optimum performance polyurethane insulation, corona surface of polyethylene pipe shell.

gas/oil /water pipeline Puf Pre-Insulated Pipe PE shell casing plastic Machinery Advantages:
Significantly increases the reliability of the pipeline in the PUF insulation system operational availability of remote condition monitoring PUF insulation, which allows to detect and repair leaking coolant, preventing accidents typical for thermal networks of other designs.
Highly cost-effective use of pipelines in the foam insulation define the following parameters:
Simplifying the construction, maintenance and repair;
Increased service life of 30-40 years (traditional types of pipelines - 5-10 years);
Reduction of heat losses to 8% (traditional types of pipelines - 30-40%);
Reducing capital costs by 15-20% (not required construction of concrete channels and chambers for valves);
Reduced operating costs by 9 times;
Reduction in repair costs 3 times.
