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.
Piping PUF insulation and fittings is a rigid structure "pipe in
pipe" consisting of steel or galvanized steel carrier pipe, a layer
of polyurethane foam insulation and the outer jacket pipe
protective of high-density polyethylene - for underground
installation or sheet galvanized steel - for above-ground pad.
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.
