The Steel Wire Reinforced Polyethylene Composite Pipe (SRTP/SRCP) represents a transformative leap in water utility pipe system products. This state-of-the-art pipe boasts a high-strength steel wire mesh skeleton, meticulously spiral-twisted and formed. It is crafted from specially modified flame-retardant and antistatic high-density polyethylene (HDPE) and bonded with a high-performance bonding resin. This remarkable pipe harmonizes the superior qualities of steel and plastic, making it the ultimate choice for rigorous applications such as underground water supply, drainage, slurry spraying, gas extraction, and gas pressure systems.
Polyethylene raw materials: Our inner and outer polyethylene resins, employed in water supply and drainage engineering applications, are derived from food-grade HDPE materials, including carbon nanotube (CNT) modified substances. During the pipe processing, no heavy metal salt stabilizers are used, ensuring the materials are non-toxic and possess excellent hygienic properties. Developed using our proprietary technology, these advanced materials enhance the mechanical properties of the pipes, surpassing MT181 and MT558.1 standards and delivering performance beyond expectations. .
Reinforced steel wire: Our pipes integrate copper-plated steel wire that conforms to the GB/T14450 standard, boasting an impressive tensile strength of up to 2050MPA. This significantly surpasses the standard requirement of 1850MPA, guaranteeing exceptional durability and outstanding performance.
Binder resin: Our proprietary binder resin technology offers unmatched adhesion to steel wire and exceptional process adaptability. This innovation ensures our pipes deliver superior reliability and robustness, even under the most demanding conditions.

Experimental Verification
Key Raw Materials
At Shandong Donghong Pipe Industry Co., Ltd., the binder resin forms the bedrock of our Engineering Support High-Density Polyethylene Pipe, guaranteeing flawless stress transfer during high-pressure scenarios. By harnessing our unique raw material design and development platform, we perfect the binder resin to deliver unmatched performance. This superior composite material seamlessly blends with our state-of-the-art processes and cutting-edge equipment, highlighting our steadfast dedication to quality and innovation.
Plating is crucial to our product's longevity, offering exceptional corrosion resistance while significantly boosting the shear strength between steel wire and bonding resin. Extensive data testing has revealed that the type of plating material greatly influences shear strength. Tin bronze plating excels with an outstanding average shear strength of 20.69MPa, compared to 11.42MPa for brass. Thus, our Reliable Srcp Tube for Water Transportation employs tin bronze-plated steel wire, ensuring it stands out as the premier substrate for pressure-bearing applications.
