Product Description Product DescriptionSteel Wire Reinforced Polyethylene Composite Pipe (SRTP/SRCP) heralds a groundbreaking advancement in water utility pipe systems. This cutting-edge pipe is fortified with a high-strength steel wire mesh skeleton, meticulously spiral-twisted and formed. Crafted from specially modified flame-retardant and antistatic high-density polyethylene (HDPE), and seamlessly bonded with high-performance bonding resin, the pipe exemplifies a unique synergy between the steel wire skeleton and the inner and outer HDPE layers. By combining the superior qualities of both steel and plastic, this robust design is perfectly suited for rigorous applications including underground water supply, drainage, slurry spraying, gas extraction, and gas pressure systems.Polyethylene raw materials: The inner and outer polyethylene resins used in our water supply and drainage engineering applications are manufactured from food-safe, specially modified HDPE materials, incorporating advanced carbon nanotube (CNT) modifiers. During pipe processing, no heavy metal salt stabilizers are added, ensuring the materials are non-toxic and possess exceptional hygienic properties. These cutting-edge materials are developed using our proprietary technology to enhance the mechanical properties of the pipes, guaranteeing that they not only meet but exceed the MT181 and MT558.1 standards, surpassing performance expectations. . Reinforced steel wire: Our pipes incorporate copper-plated steel wire that complies with the GB/T14450 standard, boasting an impressive tensile strength of up to 2050MPA, significantly surpassing the standard requirement of 1850MPA. This ensures remarkable durability and exceptional performance. Binder resin: The innovative binder resin, developed using our exclusive proprietary technology, offers unparalleled adhesion to steel wire along with excellent process adaptability. This ensures that our pipes demonstrate outstanding reliability and robustness, even in the most demanding environments.Nominal diamter /mmNominal Pressure / Mpa0.8 1.01.25 1.6 2.0 2.5 3.0 3.5 4.0 5.0 6.3 7.0 8.0 9.0 10.011.012.013.014.015.0Nominal Wall Thickness / mm50///4.55.05.55.55.56.08.59.09.510.010.010.010.010.010.010.510.563///4.55.05.55.55.56.58.59.010.010.010.010.010.510.511.511.011.075///5.05.05.5.6.06.09.59.59.510.510.510.511.511.512.012.012.012.090///5.55.55.56.06.010.010.510.511.511.511.512.012.012.012.012.513.0110/5.55.57.07.07.58.58.511.012.012.012.012.013.013.013.513.514.514.515.5125/5.55.57.58.08.59.59.511.011.012.012.013.013.015.015.015.015.015.515.5140/5.55.58.08.59.09.59.511.011.013.013.015.015.015.015.015.015.016.016.5160/6.06.09.09.510.010.510.511.012.014.014.015.015.015.015.516.016.017.017.0180/6.06.09.510.51.012.012.513.013.014.015.015.015.015.015.516.017.0//200/6.06.09.510.511.012.012.513.013.015.015.015.015.016.017.017.0///225/8.08.010.010.511.012.013.013.013.014.015.016.017.017.0/////2508.010.510.512.012.012.514.014.014.015.016.017.017.0///////2809.511.011.013.013.015.015.017.017.018.018.019.020.0///////3159.511.511.513.013.015.015.018.018.019.020.0/////////35510.012.012.014.014.017.017.019.019.020.021.0/////////40010.512.512.515.016.017.017.019.021.0///////////45011.513.513.516.018.018.019.020.021.0///////////50012.515.515.518.019.022.023.024.0////////////56017.020.020.022.022.024.026.0/////////////63020.223.023.026.026.028.0//////////////71023.026.028.030.032.0///////////////80027.030.032.034.036.0///////////////90029.033.535.038.040.0///////////////100034.037.040.045.047.0///////////////120038.040.043.050.0////////////////Certifications1.
