PERT Rigid / Flexible Pre-insulated Pipe Production Line For water
supply and refrigeration systems
The one-step PERT insulation pipe production line is unable to fulfill production requirements using conventional extrusion equipment. Consequently, the screw and barrel of the extruder, the pipe mold, and the sizing and cooling systems must be specifically engineered. Within just two years, Huashida Company successfully overcame 130 technical challenges and established China's first one-step PERT insulation pipe production line with independent intellectual property rights.
Huashida Company has subsequently developed both standard PERT insulation pipes and fiber-reinforced PERT insulation pipes, which are further categorized into two types based on their appearance and performance: flat-wall insulation pipes and corrugated insulation pipes.

PE-RTII insulation pipe
√ PERT II Pipes Can Tolerate Temperatures of 110°C
√ Pipeline smooth, no impurities, no pollution
√ Heating companies can realize unattended, automated operation
√ Low temperature heating
√ 60 °C supply water 45 °C backwater to meet the heating demand.
√ The construction is simple and convenient, and the excavation amount is 40%
√ Greatly reduce construction costs
It saves the raw materials for using PE-RT II pipe.
Example: Level 2 design pressure: 10 Bar; for cold and hot water transfer in buildings
Selection of different material pipes: the highest PE-RTIIS value; the thinnest wall thickness
Compared to PERT I, PERT II can reduce material use by 15%
Relative to PP-R, PERT II can reduce material use by 30%

More details
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.
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.
