制造能力

  • Inline steel pipe surface blast cleaning Sa 2½ before coating
  • Electrostatic FBE application with heated induction cure
  • Extruded copolymer adhesive and PE topcoat for 3PE systems
  • Integrated with Hengzhenyuan 3000T forming and mill pipe supply for export packages

工程常见问题

FBE is a single fusion-bonded epoxy layer for moderate service. 3PE adds copolymer adhesive and extruded polyethylene for long-life buried pipelines and higher mechanical protection.
Projects often reference DIN 30670 or ISO 21809-1 together with API 5L pipe. We align coating thickness and QA records to the standard named on your RFQ.
We do not advertise third-party agency certification we do not hold. Release is based on factory in-house testing, coating holiday detection, and EN 10204 3.1 mill certificates.
Yes — field joints, bends and B16.9 fittings can be quoted as a coated package from the same factory.
