Automatic Steel Pipe Internal External FBE Coating Line for Water Supply Pipelines

The internal-external FBE epoxy powder coating process for steel pipe inner and outer walls is the globally-acknowledged high-performance anti-corrosion standard for oil & gas long-distance transmission pipelines, offshore pipeline construction, municipal water supply networks and industrial fluid transportation systems.

Widely specified for large-scale energy infrastructure projects across the Middle East, Central Asia, Russia and Africa, this fully-automatic turnkey steel pipe internal-external FBE epoxy coating line delivers a complete unified FBE coating solution for regional EPC contractors, pipe fabricators and pipeline operators facing harsh desert, saline, cold-climate and coastal operating conditions.

This integrated turnkey system combines Sa2.5-grade internal & external shot blasting derusting and precision electrostatic Fusion Bonded Epoxy (FBE) epoxy powder spraying within one vendor-matched production unit for large-diameter steel pipe anti-corrosion treatment.

The equipment complies with major international project standards: DNV, SY/T0413, GB/T23257, DIN 30670, DIN 30678, SY/T0315-2005 and CNPC38-2002 - delivering comprehensive multi-standard FBE coating certification required by oil-gas tender specifications across global emerging-market energy projects.

Fusion Bonded Epoxy (FBE) powder is a thermosetting, non-toxic anti-corrosion coating material purpose-built for steel pipe surface protection, widely adopted for pipeline projects across the Middle East, Central Asia, Russia and Africa.

Key performance benefits of FBE epoxy coating:

• Outstanding FBE coating adhesion on Sa2.5 shot-blasted steel pipe internal and external surfaces
• Superior cathodic disbondment resistance, complying with DNV requirements for buried onshore & offshore oil and gas pipelines
• Powerful chemical corrosion resistance against acids, alkalis, salts, complex oilfield media and various industrial transported chemicals
• Low-friction smooth inner wall: internal FBE epoxy coating cuts fluid flow resistance and enhances transmission efficiency for long-distance oil & gas pipeline transportation
• Non-toxic formulation: fully suitable for internal lining of potable water supply pipelines, apart from oil-gas pipeline anti-corrosion service

• Fully Turnkey FBE Epoxy Coating System - Shot blasting, medium-frequency induction heating, internal & external FBE epoxy powder spraying, powder recovery and pipe end trimming are fully integrated within one harmonized production line.
• National Patented Core Technology - Supported by a domestic high-end plastic machinery expert workstation, our internal-external FBE coating line owns 10+ independent national patents.
• Specialized FBE Process Engineering Team - Nine senior engineers focus on FBE powder curing profiles, steel pipe surface preparation and dual-wall coating process optimization.
• 4,000m² Intelligent Manufacturing Factory - Full ISO9001:2015 quality management implemented throughout every manufacturing procedure.
• 99.8% Operational Stability - Each complete internal-external FBE coating line undergoes full-load factory pre-commissioning prior to shipment.
• Sa2.5 Dual-Wall Shot Blasting Performance - Simultaneously reaches Sa2.5 international cleanliness grade on steel pipe inner and outer surfaces.
• Zero-Dust-Emission Environmental Design - Equipped with dedicated powder recycling unit plus cyclone & pulse dust collectors.
• Multi-Standard EPC-Ready Compliance - Certified compatible with DNV, SY/T0413, GB/T23257, DIN 30670, DIN30678, SY/T0315-2005 and CNPC38-2002.
