The Steel Wire Reinforced PE Composite Pipe (SRTP/SRCP pipe) represents the pinnacle of modern piping technology, symbolizing superior engineering and innovation. Expertly crafted by spirally winding high-tensile steel wire for unparalleled reinforcement, this pipe is integrated with a uniquely formulated flame-retardant and antistatic HDPE matrix. These top-tier components are seamlessly bonded using a high-performance adhesive resin, creating a formidable product that combines the unmatched strength of steel with the adaptability of plastic. This ground-breaking pipe is extensively utilized in a variety of demanding mining applications, including underground water supply and drainage, shotcrete, gas drainage, and air pressure systems.
With over a decade of dedicated research and hands-on application, Shandong Donghong Pipe Industry Co., Ltd. has ascended to the forefront of the industry, becoming the definitive leader in steel wire mesh skeleton plastic (polyethylene) composite piping systems. Our pioneering solutions adeptly address the conventional pipeline issues such as brief service life, low corrosion resistance, excessive weight, rigidity, and significant friction loss. Our comprehensive piping system features a vast array of pipes, fittings, and connections, meticulously designed for high, medium, and low-pressure scenarios. These state-of-the-art systems are widely employed in underground coal mines for water supply and drainage, nitrogen injection, gas extraction, and pressurized air management. In addition to excelling in coal mining, our products deliver exceptional reliability and efficiency in the chemical industry and an extensive range of other sectors, ensuring unmatched performance and dependability.

Strong Deformation Resistance
Enhanced Foundation Settlement Resistance. Our pipes exhibit superior performance under pressure, maintaining stability even when subjected to certain bends without pressure relief.
High Composite Strength
Utilizing special modified materials, our polyethylene and coated steel wire achieve a remarkable composite strength of ≥15N/mm.
Low Overall Cost
Our pressure-bearing pipes primarily rely on steel wire, significantly reducing polyethylene consumption and offering clear cost advantages. The ability to connect pipes outside the ditch minimizes earthwork excavation, streamlining connections and reducing construction expenses. Additionally, the lightweight nature of the pipe decreases dependence on large equipment.
Easy to Transport and Construct
Our flexible pipes can be tailored to various lengths, significantly reducing the number of joints. With a weight approximately half that of steel pipes and a third of cement pipes, the need for large-scale installation equipment is minimized.
Excellent Hygienic Performance
Featuring anti-corrosive materials, our pipelines resist bacterial growth and eliminate the 'yellow water' issue common in traditional pipelines.
Safe and Reliable Connection
Employing electrofusion and mechanical connections, our pipes are versatile and meet the demands of diverse application environments.
