Product Description
Huashida took 2 years to overcome about 30 technical difficulties,
and developed a new one-step polyurethane foam flexible
pre-insulated pipe production line with independent intellectual
property rights.
The new one-step polyurethane foam pre-insulated pipe
production'line includes the following processes:
The pressure-bearing and heat-resistant PERT inner working pipe
extrusion, polyurethane foaming, polyurethane curing and
corrugation forming,HDPE jacket coating. The whole process is
online continuous production.
This production line is suitable for making both flexible
polyurethane foam pre-insulated pipes and rigid polyurethane foam
pre-insulated pipes, and the pipe diameter range is from 20mm to
350mm.

Extruder: PERT special single screw extruder, extrusion part using forced
water cooling feeding section, machine barrel slotted, the power
consumption of the main drive motor is greatly reduced; Screws with
a large length-to-diameter ratio (25-38:1) have excellent
plasticizing effects.
Extruder head: professional PERT pipe mold, smooth inner and outer surface of the
pipe, uniform wall thickness, special treatment of the flow
channel, more wear-resistant, PERT pipe dedicated efficient head.
Vacuum calibration box: Uniquely designed sizing sleeve, all-stainless steel vacuum box,
using PERT pipe dedicated sizing sleeve, accurate sizing and good
effect; High-efficiency spray cooling ensures the quality of the
pipe materials.
Coating die head: With a vacuum coating mold of invention patent and a specially
designed coating die head, it ensures uniform thickness of the
coating layer.
Winding machine: A fiber-reinforced device with an invention patent, featuring
efficient fiber weaving to ensure the strength of the pipe.
Chipless cutting machine: Wide range cutting from 32 to 200mm; High-strength alloy steel
blades, rotary knife cutting, smooth and flat pipe cutting edge
with small error; The cutting follow-up ensures the precise cutting
position; Professional PLC control, accurate operation; The feed
position is specially designed to ensure that the cutting is
completed in one go.
Application Scenarios
Huashida's continuous PERT insulated pipe pipes are ideal for a wide range of applications, including
district heating, cooling systems, oil and gas pipelines, and
industrial piping. Their superior insulation, anti-corrosion
properties, and long service life make them the preferred choice
for modern, sustainable piping systems.
