The core technology of Huastar PE960-1880 insulation pipe production line is at the leading level in China, and a number of innovation points and design concepts have filled the gaps in China, among which four core technologies such as solid-liquid phase separation screw, spiral diverter head, DCL human-machine dialogue technology, and real box external manipulator technology are the first or first applied in the industry. This product is also the only domestic production line capable of manufacturing 1880mm large diameter insulation pipe.

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.
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.
