3PE / Three-layer polyethylene

3LPE three-layer polyethylene‑coated steel pipes are specially designed for underground pipeline projects and are widely used in oil, natural gas, and potable water transmission lines. Their key advantages include long‑lasting corrosion resistance, low water absorption, and excellent mechanical strength. These products can also be applied to coal‑mine slurry pipelines, high‑pressure cable protection casings, wind‑energy infrastructure, bridge construction, and steel pipe foundations for high‑speed railways. Our factory offers standard pipe grades such as ASTM A672 C70 CL22, AS1163 C350, and Q345B spiral welded pipes, and provides global customers with bulk wholesale and custom fabrication services.
