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.
