2LPP corrosion-resistant steel pipe

Double‑layer polypropylene (2LPP) coated anti‑corrosion steel pipes are manufactured using a specialized one‑step polypropylene spray coating process, offering long‑lasting corrosion protection, low water absorption, and excellent mechanical strength. They are widely used in oil and gas transmission pipelines, municipal utility networks, coal‑water slurry pipelines in coal mines, high‑pressure industrial pipelines, as well as in wind power, bridge, and high‑speed railway steel structure projects. This coating achieves strong adhesion, high hardness, and a fine gloss without requiring complex pre‑treatment, while its film exhibits outstanding resistance to UV exposure, high temperatures, and water erosion. The simplified spraying process reduces labor, energy, and construction time costs. Our factory employs 170 full‑time staff, maintains an in‑house technical R&D team, ensures standardized support across all functional departments, and enforces rigorous quality‑control measures. We can accommodate both large‑volume wholesale orders and custom‑made requests, with clear price advantages.
