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.
2 meters PE thermal insulation pipe production line which
manufactured in SHANGHAI JWELL PIPE EQUIPMENT CO.,LTD , have a
leading position in the industry, and the design is unique and
novel . Adopt high efficiency single screw extruder , high degree
of automation, easy operation, continuous production, stable and
reliable.Due to the equipment production is stable ,mature
technology ,customers are very satisfied .

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.
The main performance indicators and technical innovations of the
PE960-1880 insulation pipe production line are as follows:
1. Basic performance indicators: pipe diameter range 960-1880mm,
pipe wall thickness 14-17mm, production speed 0.1-0.45m/min, total
installed capacity of 550kw.
2. The application of solid-liquid phase separation screw
technology, the service life and output of the ordinary screw is 3
times, can achieve high-speed and efficient extrusion melting, and
can ensure the quality of plasticization.
3. The spiral shunt head of the gas water supply pipeline is
successfully applied to the production of large thin-wall pipes.
The production pipe has high internal pressure strength, no trace
of confluence, the pipe is stable and reliable, and it is not easy
to break, and the scaffold shunt head is eliminated.
