Product Description

gas/oil /water pipeline Puf Pre-Insulated Pipe PE shell casing plastic Machinery

HDPE Jacket pipe extrusion line for pre-insulated pipe is designed by Qingdao Huashida Machinery Co., LTD. It absorbs and improves developed HDPE pipe extruding technology.

The production line is an integration design composed by extrusion, vacuum calibrating, cooling, pulling, cutting, stacker. Great performance in automatic operation, extrusion capacity, steady and service life etc. Especially compared with the line use internal pressure method, vacuum calibrating method is much better than it for stiffness, pressure resistance and surface smooth.Vacuum calibrating method pre-insulation pipe outside casing extruded line is the advanced and popular machinery in the world.

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.

1060mm Natural Gas Pipeline Insulation Pipe Extrusion Machinery Pipe Making Machine


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.
