Corrosion Resistance Our anti-corrosion materials, including polyethylene and epoxy resin, are advanced polymers with outstanding corrosion resistance, effectively shielding the pipeline from soil and fluid damage. This significantly extends the pipeline's service life. 2. Excellent Hydraulic Properties With a smooth inner wall that resists scaling and a low coefficient of friction, our pipes ensure optimal conveying capacity. The non-adhesive properties further reduce pressure loss and minimize water transmission energy consumption. 3. Superior Hygiene Performance The epoxy resin coated inner surface is smooth and resists scaling, meeting GB/T17219 health standards for safety and hygiene. This ensures the pipeline does not contaminate the water quality, maintaining it pure and safe. 4. Superior Coating Adhesion Modified epoxy resin and polyethylene powder form strong chemical bonds with the metal, ensuring robust adhesion. The outer polyethylene layer offers excellent toughness and impact resistance, preventing damage from dragging, knocking, and plant root punctures. 5. Extended Lifespan Our anti-corrosion steel pipes can last 30 to 50 years under normal construction and usage conditions, greatly surpassing the lifespan of ordinary steel pipes. 6. Secure Connections Multiple connection methods are available to suit various environments and pressure requirements. Options include flanged, quick coupling, butt welding, stainless steel lining, and socket connections. Each method ensures mature and reliable connectivity. Appliation CasesOur Advantages 1.
