Internal External Fusion Bonded Epoxy Coating Line with Shot Blasting for Pipelines

A fully automatic, turnkey FBE pipe coating line integrating Sa2.5 dual-wall shot blasting with precision electrostatic fusion bonded epoxy coating for municipal water supply, oil and gas transmission, offshore, and industrial fluid pipelines.

The internal and external FBE coating process for steel pipe inner and outer walls is a globally recognized high-performance pipeline anti-corrosion standard. It is widely specified for municipal water supply pipelines, oil and gas long-distance transmission lines, offshore pipeline construction, and industrial fluid transportation systems, and is deployed across large-scale pipeline projects in the Middle East, Central Asia, Russia, and Africa. This fully automatic line gives EPC contractors, pipe fabricators, and pipeline operators a complete steel pipe coating solution for harsh desert, saline, cold-climate, and coastal operating conditions.

The line combines Sa2.5-grade internal and external shot blasting with precision electrostatic fusion bonded epoxy coating in one matched production unit. It covers every phase of the process: pipe uploading, internal and external shot blasting, medium frequency induction heating, simultaneous internal and external epoxy powder spraying, powder recovery, and finished pipe unloading. PLC control manages the full continuous workflow with processing capacity of up to 250 m²/h, minimizing operating risk for high-volume pipe coating workshops.

Unlike fragmented setups that require separate pipe shot blasting machines and coating hardware from multiple suppliers, this epoxy powder coating line integrates every stage into a single system. That removes multi-vendor sourcing and system integration risk for pipeline coating equipment buyers, pipe mills, and EPC contractors.

The equipment is designed to meet DNV, SY/T0315-2005, and CNPC38-2002 coating specifications, delivering the FBE compliance that water supply, oil and gas, and municipal infrastructure tenders require.

Steel pipes processed by this coating machine achieve superior anti-corrosion performance. The fully cured fusion bonded epoxy coating resists long-term erosion from acids, alkalis, salts, chlorine, and oxidizers — critical for municipal water networks in the Middle East, cold-climate trunk lines in Russia, high-salinity gathering networks in Central Asia, and coastal pipelines in Africa. The dense, smooth surface lowers fluid friction loss and raises throughput for long-distance water supply and oil and gas transmission, while excellent cathodic disbondment resistance meets strict international pipeline coating requirements.

Fusion bonded epoxy (FBE) powder is a thermosetting, non-toxic anti-corrosion coating material engineered for steel pipe surface protection. It is widely used in municipal water supply and oil and gas pipeline construction across the Middle East, Central Asia, Russia, and Africa. Cured at high temperature onto Sa2.5 blast-cleaned steel, the epoxy powder forms a dense, cross-linked protective layer with strong chemical corrosion resistance, wear resistance, anti-aging performance, and high mechanical strength.

Internal and external FBE coating bonds to both the inner and outer pipe walls simultaneously, creating a seamless, void-free barrier for large-diameter water supply networks, oil and gas trunk lines, gathering pipelines, and industrial fluid systems in desert, cold-climate, saline-soil, and coastal conditions.

• Non-Toxic Internal FBE Coating: A smooth epoxy lining suited to potable water supply pipeline internal protection and oil and gas pipeline service.
• Strong FBE Adhesion on Sa2.5 Shot-Blasted Steel: Internal and external shot blasting creates the anchor profile that maximizes bond strength for long-term buried service.
• Superior Cathodic Disbondment Resistance: Supports buried onshore and offshore water supply and oil and gas pipelines.
• Powerful Chemical Corrosion Resistance: Protects against acids, alkalis, salts, chlorine, oilfield media, and industrial transported chemicals.
• Low-Friction Smooth Inner Wall: The internal coating cuts fluid flow resistance and improves transmission efficiency for long-distance pipelines.
• Complete Dual-Wall Protection: One steel pipe coating line protects the inside and outside of every pipe in a single pass.

• Fully Automatic Turnkey FBE Pipe Coating Line: Shot blasting, medium frequency induction heating, internal and external epoxy powder spraying, and powder recovery are integrated in one matched production line, ready to deploy from day one.
• Non-Toxic Internal FBE for Water Supply Pipelines: The internal fusion bonded epoxy coating suits potable water supply pipeline lining — a key advantage over coating lines built only for oil and gas.
• National Patented Core Technology: Backed by a domestic high-end plastic machinery expert workstation with 10+ independent national patents, setting this line apart from generic competitors.
• Specialized FBE Process Engineering Team: Nine senior engineers focus on FBE powder curing profiles, steel pipe surface preparation, and dual-wall coating optimization, drawing on 50+ cross-border pipeline coating projects.
• 4,000 m² Intelligent Manufacturing Factory: ISO9001:2015 quality management runs through every manufacturing procedure, ensuring consistent quality for export-oriented pipeline coating equipment.
• 99.8% Operational Stability: Every line undergoes a full-load factory test run before shipment, greatly reducing on-site debugging risk for international EPC contractors.
• Sa2.5 Dual-Wall Shot Blasting: The pipe shot blasting machine reaches Sa2.5 cleanliness on inner and outer surfaces simultaneously — the surface preparation standard for buried pipeline FBE coating.
• Low-Dust Environmental Design: A dedicated powder recycling unit plus cyclone and pulse dust collectors meet CE and ISO14001 environmental standards and local workshop emission rules.
• Wide Diameter Range with Customization: Models cover steel pipe from 325 mm to 4200 mm, with customizable diameter, coating thickness (80–800 μm), and line speed (0–6 m/min).
• Multi-Standard EPC Compliance: Compatible with DNV, SY/T0315-2005, and CNPC38-2002 FBE coating specifications for international tender documents.
