Wuzhou Brand 426mm OD 3PE External & EP Internal Spiral Welded Pipe | Special for Oil & Gas Transmission, Export Grade
Produced by Cangzhou Spiral Steel Pipe Group, Wuzhou 426mm OD spiral welded pipe with 3PE external anti-corrosion and EP internal coating is tailor-made for long-distance oil & gas transmission pipelines. It strictly complies with GB/T23257-2017 (3PE) and CJ/T120-2016 (EP) national standards, as well as international certifications including API 5L and ISO 3183, being the first choice for exported oil & gas pipeline projects.
Made with double-sided automatic submerged arc welding process, customizable wall thickness from 6mm to 12mm. The external 3PE coating consists of ≥120μm FBE, ≥170μm adhesive and 2.2mm (general grade)/2.9mm (enhanced grade) PE; the internal fusion-bonded epoxy coating is ≥0.4mm. The steel pipe surface reaches Sa2.5 derusting grade, with excellent resistance to soil and medium corrosion. The smooth internal surface reduces head loss and prevents scaling, suitable for buried, mountain and other working conditions.
inspected by ultrasonic, X-ray, hydrostatic pressure and coating peel strength tests, with epoxy curing degree ≥95﹪, cathodic disbondment ≤5mm and impact strength ≥8J/mm. Complete export qualifications and third-party test reports are available, and the products have been exported in bulk to the Middle East, Southeast Asia, Central Asia and other regions. Our professional foreign trade team provides one-stop export services including certification, packaging and customs clearance.
