PU Sprayed Foaming HDPE Winding Preinsulation Pipe Manufacturing System
Pipe diameter range: 500-1600MM
Polyurethane spraying polyethylene wrapping pre-insulated pipe
production line is used for the production of polyurethane
prefabricated direct buried thermal insulating pipes, which are
widely used in the field of heating, cooling and crude oil
transportation.
Main features of the PU Spray insulation pipe:
1. The density of polyurethane is uniform and controllable.
2. Polyurethane rigid foam has no empty spaces.
3. The surface of polyurethane foam is rough, the shear strength
(friction) to the polyethylene outer casing is greater than 200Kpa.
4. The thickness of the polyurethane insulation layer and the
thickness of the polyethylene outer casing can be adjusted
according to the design.
5. The production has a high degree of automation.
The spraying and winding production process ensures the uniformity
of the density of the insulation layer, improves product quality,
and reduces production costs.
PUF spray PE winding preinsulated pipe production line consists of the following parts:
3) Polyethylene sheet extruding winding line
4) Water cooling line
5) End-cutting equipment

Rust Removal
First, the surface of the steel pipe is derusted, usually by shot
blasting or sand blasting, to ensure that the surface is clean and
free of rust, oil and other impurities. Preheating: The cleaned
steel pipe is preheated so that the subsequent polyurethane foam
can better adhere to the steel pipe surface.
Polyurethane spray molding line
The polyurethane raw materials (isocyanate and polyol) are mixed in
a high-pressure foaming machine and evenly sprayed onto the surface
of the preheated steel pipe. The polyurethane raw materials rapidly
foam on the surface of the steel pipe, forming an insulating layer.
Polyethylene sheet extruding winding line
Polyethylene (PE) is wrapped around the polyurethane insulation
layer to form an outer sheath. Cooling and shaping: The wrapped
pipe is cooled and shaped to ensure that the outer sheath and
insulation layer are tightly bonded to form a stable structure.

Qingdao Huashida Machinery Co., Ltd was established in 2003. Since
its inception, Huashida has focused on plastic polyurethane
insulation pipe production line, 3LPE anticorrosion pipe production
line, large diameter underground pipe production line and plastic
pipe joints for 20 years. We always attach great importance to
research and development,collaborating closely with Beijing
University of chemical technology, Qingdao university of technology
and scientific research institutions. by absorbing advanced
technology home and abroad, after 22 years of endeavor we now rank
one of the top 3 manufacturers in the industry in China. Huashida
machines have been well received in Saudi Arabia, Kazakhstan,
Uzbekistan, United Arab Emirates, Turkey, Russia, etc.
