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.
Innovation is endless, so Qingdao Huashida Machinery Co., Ltd. has
always been on the road of tracking the world's cutting-edge
technology. It is under the guidance of such ideas that the
one-step PERT insulation pipe production line developed by the
company has maintained a leading level in the industry in terms of
special process technology, filled the domestic gap, and a number
of intellectual property rights have been granted patents by the
State.
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.

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.
