Technical Prameters:

PE insulation pipe also called PE outer protective tube, jacket tube, sleeve tube .Direct burying PE insulation pipe is made up of high density polyethylene outer protective layer, polyurethane rigid foam plastic insulation material and steel pipe.The insulation material is rigid polyurethane foam ,the density is 60kg/m3~80kg/m3 , fully fill the gap between steel pipe and casing pipe,and have a certain degree of adhesive strength. Form a firm whole between the steel pipe, the outer tube and the insulation layer. Foam of Polyurethane directly buried insulating pipe has good mechanical and thermal insulation properties . Under normal situation, it can withstand high temperatures of 120°C and can withstand high temperatures up to 180°C through modification or combination with other insulation materials.Applicable to a variety of cold, hot water, high and low temperature pipeline’s insulation engineering.

Vacuum calibrating method pre-insulated pipe outside casing extrusion line is the most advanced and popular machinery in the world.In the practice of domestic construction becomes increasingly used energy-saving technology trenchless laying of pipelines, using pipes and fittings with industrial thermal insulation of rigid polyurethane foam (PUF insulation) in protective shell.
Pipelines PUF insulation intended for installation of heating networks with a working pressure of 1.6 MPa and a water temperature to 403 ° K (130 ° C) with a valid short-term increase in temperature to 423 ° K (150 ° C).


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.
