Exceptional Corrosion Resistance Crafted from superior anti-corrosion materials, our epoxy-coated steel pipes employ polyethylene and epoxy resin, renowned for their remarkable corrosion resistance. This ensures robust protection against soil and fluid damage, significantly extending the pipeline's service life. 2. Superior Hydraulic Properties The smooth inner wall design minimizes scaling and boasts a low coefficient of friction. Its slick surface ensures efficient conveyance capacity, reducing both pressure loss and energy consumption during water transmission. 3. Impeccable Hygiene Performance The epoxy resin coating inside the pipeline offers a smooth, non-scaling surface that is both safe and hygienic. Complying with GB/T17219 health standards, it effectively prevents water contamination, maintaining high water quality. 4. High Adhesion Coating Our advanced epoxy resin and polyethylene powder raw materials create a durable chemical bond with metal, ensuring strong adhesion. The external polyethylene layer adds robustness, impact resistance, and protection against dragging, knocking, and plant root punctures. 5. Extended Lifespan Engineered for longevity, our anti-corrosion steel pipes boast a continuous use lifespan of 30 to 50 years under normal construction and operating conditions, far surpassing that of standard steel pipes. 6. Secure Connections Offering a variety of connection methods to suit diverse environments and pressure requirements, our pipes are compatible with flanged, quick coupling, butt welding, stainless steel lining, and socket connections. These methods ensure mature and reliable connections. Appliation CasesOur Advantages 1.
