Steel wire reinforced PE composite pipe (known as SRTP/SRCP pipe) is meticulously crafted by spirally winding high-strength steel wire as the reinforcement and utilizing modified flame-retardant and antistatic HDPE as the core matrix. These components are bonded together using high-performance adhesive resin, resulting in a revolutionary mining product that marries the unparalleled strengths of both steel and plastic pipes. This innovative pipe system finds extensive applications in underground water supply and drainage, shotcrete, gas drainage, and air pressure systems. Its superior design ensures enhanced durability, safety, and reliability in demanding underground environments.
Shandong Donghong Pipe Industry Co., Ltd. boasts over a decade of expertise in the research and application of steel wire mesh skeleton plastic (polyethylene) composite piping systems. Our pioneering solutions have addressed traditional pipeline shortcomings such as short service life, poor corrosion resistance, heavy weight, limited flexibility, and high friction loss. Our comprehensive piping system includes an extensive range of pipes, fittings, and high, medium, and low-pressure connections. These systems are extensively deployed in diverse sectors including underground coal mines for water supply and drainage, nitrogen injection, gas extraction, and pressurized air, as well as in non-coal mines, the chemical industry, and various other fields. Trust us for superior performance and long-term reliability in your demanding applications.

Exceptional Deformation Resistance
Enhanced foundation settlement resistance ensures no pressure relief at certain bends, even under significant load.
Superior Composite Strength
Polyethylene and coated steel wire are meticulously composited with specialized modified materials, boasting a composite strength of ≥15N/mm.
Cost-Efficient Solution
The pipeline's pressure resistance is predominantly provided by steel wire, significantly reducing polyethylene consumption and offering substantial cost advantages. It can be assembled outside the ditch, minimizing earthwork excavation and accelerating connection time, thereby cutting construction costs. Its lightweight nature diminishes reliance on heavy equipment.
Effortless Transportation and Construction
These flexible pipes can be tailored to various lengths, reducing the number of joints significantly. With a weight of approximately half that of steel pipes and one-third of cement pipes, the need for large-scale installation equipment is notably decreased.
Outstanding Hygienic Performance
The anti-corrosive pipeline material resists bacterial growth, eliminating the 'yellow water' issue common in traditional pipelines.
Safe and Reliable Connections
Electrofusion and mechanical connections are generally used, ensuring adaptability to diverse application environments.
1. Basic material: high-density polyethylene; 2. Skeleton material: high-density copper steel wire; 3. Composite material: adhesive resin; 4. Supporting pipe fittings production workshops; 5. Quality control of steel wire coating supplier; 6. Customization capability; 7. Precision equipment.
