The Steel Wire Reinforced PE Composite Pipe (SRTP/SRCP pipe) is a hallmark of cutting-edge innovation, representing the zenith of modern engineering excellence. Crafted with precision, this pipe features high-strength steel wire meticulously spirally wound for unparalleled reinforcement. This core is encased in a specially modified, flame-retardant, and antistatic HDPE matrix. Seamlessly bonded with high-performance adhesive resin, the result is a robust and reliable pipe that combines the formidable durability of steel with the flexible versatility of plastic. This groundbreaking design is extensively utilized in various mining operations, including underground water supply and drainage, shotcrete, gas drainage, and air pressure systems.
For over a decade, Shandong Donghong Pipe Industry Co., Ltd. has been at the forefront of steel wire mesh skeleton plastic (polyethylene) composite piping technology. Our relentless research and practical expertise have established us as industry leaders, adept at overcoming traditional pipeline issues such as limited service life, low corrosion resistance, heavy weight, inflexibility, and high friction loss. Our comprehensive piping solutions include a diverse array of pipes, fittings, and connections, engineered for high, medium, and low-pressure applications. These advanced systems are widely implemented in underground coal mines for water supply and drainage, nitrogen injection, gas extraction, and pressurized air management. Beyond coal mining, our products deliver unmatched reliability and efficiency to the chemical industry and numerous other sectors, ensuring superior performance and trust.

Strong Deformation Resistance
Enhanced Foundation Settlement Resistance. Our pipes showcase exceptional performance under pressure, ensuring stability even during certain bends without the need for pressure relief.
High Composite Strength
By harnessing specially modified materials, our polyethylene and coated steel wire achieve an extraordinary composite strength of ≥15N/mm.
Low Overall Cost
Our pressure-bearing pipes predominantly rely on steel wire, drastically reducing polyethylene consumption, thus offering significant cost benefits. The capability to connect pipes outside the ditch minimizes earthwork excavation, streamlining connections and cutting down on construction costs. Moreover, the lightweight design of the pipe lessens the need for large equipment.
Easy to Transport and Construct
Our flexible pipes can be tailored to various lengths, significantly reducing the number of joints required. With a weight approximately half that of steel pipes and a third of cement pipes, the need for large-scale installation equipment is greatly minimized.
Excellent Hygienic Performance
Incorporating anti-corrosive materials, our pipelines effectively resist bacterial growth and eliminate the 'yellow water' issue commonly associated with traditional pipelines.
Safe and Reliable Connection
Utilizing both electrofusion and mechanical connections, our pipes are versatile and capable of meeting the demands of diverse application environments.
