Xinyuanfeng has recently upgraded its quality control standards for TPEP double‑coated anti‑corrosion steel pipes. By strengthening requirements for coating pretreatment, we have further guaranteed excellent coating adhesion and impact resistance. The optimized anti‑corrosion pipes are well‑suited for municipal water supply, sewage drainage and long‑distance water‑transmission infrastructure projects, with greatly extended service life. Focusing on high‑quality procurement and reliable supply, Xinyuanfeng continuously upgrades its supply system of 3PE, FBE, IPN8710 and other anti‑corrosion pipes, supplying high‑quality coated steel tubes for pipeline projects at home and abroad.
