Steel Wire Reinforced PE Pipe For Water Supply High-Density Polyethylene Composite Material

The Steel Wire Skeleton Polyethylene Composite Pipe, also known as SRTP pipe, is an advanced modified pipeline. It features a high-strength steel wire mesh skeleton formed by left-right spiral winding as the reinforcement, with high-density polyethylene (HDPE) as the matrix. High-performance modified adhesive resin tightly bonds the steel wire skeleton with the inner and outer HDPE layers, combining the advantages of steel and plastic pipes while overcoming their individual drawbacks.

Product Introduction

With excellent pressure resistance and flexibility, the SRTP pipe is ideal for long-distance buried water supply and gas transmission pipeline systems. It uses polyethylene electro-fusion fittings: during connection, the internal heating element of the fitting melts the outer plastic of the pipe and the inner plastic of the fitting, creating a safe and reliable fusion bond.

Structural Advantages

Rigid-Flexible Composite Structure: The steel wire skeleton provides steel-like pressure resistance, while the HDPE matrix offers plastic-like flexibility, effectively withstanding deformation from ground settlement and impact.
Multi-Layer Protection: A three-layer integrated structure (inner/outer HDPE + middle steel wire skeleton) combined with adhesive resin prevents delamination and ensures long-term durability.

Physical Properties

High Strength & Pressure Resistance: The steel wire skeleton bears ~2/3 of the structural load, enabling high burst pressure and suitability for high-strength applications like long-distance buried water supply.
Anti-Creep Stability: The steel mesh constrains HDPE creep, maintaining high mechanical strength at room temperature, low linear expansion coefficient (35.4×10⁻⁶/℃), and excellent dimensional stability.
Temperature Resistance: Strength loss is <5% per 10℃ temperature rise (far less than pure plastic pipes), adapting to wide temperature variations (-40℃ to 80℃).

Chemical Properties

Corrosion Resistance: Inner/outer HDPE layers resist erosion from acids, alkalis, salts, and other chemical media, eliminating electrochemical corrosion and extending service life.
Hygienic & Environmentally Friendly: Smooth inner surface prevents scaling, ensuring safe water quality; lead-free, non-toxic, and fully recyclable.

Hydraulic & Construction Features

Efficient Water Transport: Ultra-smooth inner wall (surface roughness 0.01mm) reduces friction by 30% compared to steel pipes, enhancing flow efficiency and self-cleaning ability.
Easy Installation: Electro-fusion connection enables fast, reliable sealing without complex anchoring; flexibility allows above-ground prefabrication and adaptation to rugged terrain.
Long-Life Economy: Designed for a 50-year service life with minimal maintenance, significantly reducing long-term operation costs.
