01 / Project fit check
Pressure first.
Product second.
Direct answer
Water-supply reinforced PE composite pipe serves water transmission and other pressurized duties. Polyethylene forms the flow passage and protective layers, while steel wire reinforces the pipe wall.
Are operating conditions defined?
Medium, operating pressure, design pressure, surge, temperature and design life form the technical basis.
Does connection need coordinated review?
Diameter, composite structure, site equipment and the governing standard determine the approved jointing path.

02 / The cost of assumption
P
One test result proves one configuration—not an entire catalogue.
Pressure basis
Operating, design, test and surge pressure are different engineering inputs.
Available combinations
Not every published diameter is offered at every listed pressure class.
Composite identity
This system must not be specified as ordinary solid-wall PE pipe.
System integrity
Pipe, fittings, transitions and joints share pressure-boundary responsibility.
03 / What it is
A composite structure with separate material roles.
Polyethylene provides the sealed, corrosion-resistant medium path and protective system. Steel-wire reinforcement provides the principal strengthening function.
PE medium path
Creates the fluid-contact surface and corrosion-resistant bore.
Steel-wire reinforcement
Changes how the product carries structural demand compared with ordinary solid-wall HDPE.
Thermally bonded composite
Bonding and protective polyethylene complete the integrated wall and fitting interface.
Engineering boundary: Final suitability depends on medium, operating and design pressure, diameter, temperature, surge, connection, installation method and applicable standard.
04 / From feature to project value

A dash means that this diameter and pressure combination has no standard wall value in the table. Contact our technical team for other requirements, including 3.0 MPa.
DN means nominal size; confirm whether the specified series is based on inside diameter (DN/ID) or outside diameter (DN/OD). Do not treat DN as a measured diameter. SN indicates nominal ring stiffness, normally expressed in kN/m²; confirm the test method and required class. PE means polyethylene; HDPE means high-density polyethylene. PE80 and PE100 are material strength classifications, not pressure ratings.
Use the table for preliminary selection. Confirm final dimensions, pipe construction, pressure rating or ring stiffness and compatible joints against the project requirements. Pressure-test results for one specimen do not establish the rating of every diameter or configuration.

11 / Project questions
Specific answers beat big promises.
What is water-supply reinforced PE composite pipe used for?
It is reviewed for water transmission, regional transfer, irrigation, industrial water and other pressurized duties where the composite structure fits project requirements.
Is this ordinary solid-wall PE pressure pipe?
No. It uses a steel-wire-reinforced PE composite structure with separate sealing, protective and strengthening roles.
Does every diameter cover every pressure class?
Available pressure classes and wall thicknesses vary by diameter. Use the matching row in the technical table for selection.
What does the DN560 test prove?
It is one published test case. It is not a universal rating for every diameter, wall configuration or project condition.
Water-supply PE composite pipe
Steel-wire reinforcement in the pressure-pipe wall
Water-supply reinforced PE composite pipe is made by spiral winding steel-wire-reinforced PE strips, bonding adjacent strips and adding an outer PE protective layer. Additional composite PE and steel-wire reinforcement join neighbouring strips between them.
Download the English brochure (PDF) ↓ · Download centre →
Spiral-wound body and protected steel wire
The steel-wire-reinforced strip, bonded seams and outer PE layer work together to form the composite pressure wall. The pipe is used for water transfer and other compatible media.
02 / Materials
Three material roles
High-molecular-weight PE base
Combines flexibility and bonding performance to form the flow passage and composite base.
Carbon spring-steel wire
High-strength wire reinforces the pipe wall, with tensile strength of approximately 2000 MPa.
Modified PE bonding material
Heat bonds adjacent strips and composite layers for adhesion, impact resistance and crack resistance.
04 / Product characteristics
Six product characteristics
01Flexibility, impact and corrosion resistance
The PE wall combines corrosion resistance and flexibility, with interlayer peel strength above 400 N/cm.
02Pressure duty and hoop reinforcement
Steel wire is bonded with the PE base to reinforce the pressure wall. Check the diameter, wall and joint for each pressure class.
03Integrated composite layers
PE encases the wire, while heat-bonded strips form an integrated composite wall.
04Spiral-wound manufacture
Spiral winding and heat bonding reduce the equipment rotation space needed for large-diameter production.
05Longitudinal flexibility
Circumferential wire reinforcement retains longitudinal flexibility for route planning.
06Large-diameter route
Spiral winding supports large diameters, with sizes from DN50 to DN5000.
05 / Water-pipe jointing
Four connection methods
Select the connection method to match diameter, pressure class and site conditions.
01
Butt-fusion welding
Both pipe ends are prefabricated with double-flat solid-wall profiles and thickened PE joint ends, then butt-fused on site with a PE butt-fusion machine. Callouts: 1 pipe; 2 PE joint end; 3 locating step; 4 weld bead.
02
End-face electrofusion
Resistance wires are embedded at even spacing in the PE joint end faces and energised on site to fuse the two faces; compact units allow multiple simultaneous welds. Callouts: 1 joint bead end face; 2 circular heating wire; 3 W-pattern heating wire; 4 power terminal.
03
Electrofusion sleeve
A PE sleeve with embedded heating wire receives the two prepared pipe ends; after electrofusion and cooling, the internal supports are removed. Callouts: 1 pipe; 2 fusion zone; 3 sleeve.
04
Double-seal sleeve
Two sealing rings seated between pipe and sleeve are compressed against the pipe outer wall and sleeve inner wall — simple to install with dual sealing. Callouts: 1 pipe; 2 electrofusion sleeve; 3 dual sealing rings.
06 / Applications
