Energy Saving FBE Powder Coating Equipment for Drainage Pipelines with Dust Collection

Internal & External FBE Powder Coating System for Large-Diameter Steel Pipes

This energy saving FBE coating equipment is a fully automatic, modular steel pipe coating production system for factory-applied fusion bonded epoxy anti-corrosion treatment of large-diameter steel pipes. It serves drainage and sewage pipelines, municipal water supply networks, oil and gas transmission lines, industrial fluid pipelines, and buried pipeline infrastructure. Built to meet SY/T0315-2005, CNPC38-2002, and DNV coating specifications, this pipeline anti-corrosion equipment gives pipe fabricators and EPC contractors a reliable route to international project compliance.

Designed for drainage pipe manufacturers, municipal pipeline fabricators, oil and gas pipe producers, and EPC contractors, this drainage pipe coating line delivers continuous internal and external pipe coating from one integrated platform. The line is actively deployed across Russia, Iran, the UAE, India, Belarus, Kazakhstan, and other international pipeline markets.

This complete pipe coating production line integrates internal and external shot blasting derusting (Sa2.5), cyclone and pulse dust collection, medium frequency induction heating (±2°C accuracy), electrostatic FBE epoxy powder spraying, a closed-loop powder recycling system, and centralized PLC automatic control. At an adjustable line speed of 0–6 m/min, it delivers up to 250 m²/h processing capacity, or up to 2 million square meters per year, for steel pipe anti-corrosion manufacturing.

Fusion bonded epoxy (FBE) powder is a non-toxic, thermosetting anti-corrosion coating material. After precision high-temperature curing at ±2°C accuracy, it forms a dense, high-molecular cross-linked protective film. The film gives outstanding chemical corrosion resistance, anti-aging performance, and high mechanical strength.

The FBE layer bonds tightly to the Sa2.5 blast-cleaned steel surface, providing superior adhesion, acid and alkali tolerance, and excellent cathodic disbondment resistance. This is the core performance indicator for buried drainage, water supply, and oil and gas pipelines. The smooth, dense coating also reduces friction resistance during fluid transportation and improves pipeline transmission efficiency.

• Energy Saving Coating Line Design: Medium frequency induction heating with ±2°C control heats the pipe wall directly and avoids wasted heat, while the powder recycling system returns unused powder to production. Together they lower power and material consumption per pipe.
• Dust Collection and Clean Shot Blasting: The pipe shot blasting machine works with cyclone and pulse dust collectors to reach Sa2.5 cleanliness, giving the epoxy powder strong adhesion on every pipe.
• Drainage Pipeline Protection: Fusion bonded epoxy coating resists acids, alkalis, and salts, and its smooth surface lowers flow resistance in municipal drainage, sewage, and industrial wastewater pipelines.
• ±2°C Heating Precision: Uniform epoxy powder melting and curing give consistent FBE coating quality batch after batch.
• High-Throughput Performance: Full PLC automatic control sustains up to 250 m²/h at 0–6 m/min adjustable line speed, keeping high-volume pipe coating contracts on schedule.
• Wide Diameter Coverage: This steel pipe coating equipment handles pipe diameters from 325 mm to 4200 mm, with full customization of the diameter range.
• Multi-Standard Compliance: Meets SY/T0315-2005, CNPC38-2002, and DNV coating specifications for international pipeline projects.

The flexible, modular design of this epoxy powder coating machine supports internal and external FBE coating for steel pipes of different diameters and wall thicknesses. This makes the line suitable for drainage and sewage pipelines, municipal water supply pipes, long-distance oil and gas transmission pipes, and diversified industrial buried pipeline coating projects. Diameter range, coating thickness, and production speed can all be customized to your project requirements.

Precision medium frequency induction heating maintains ±2°C temperature accuracy, ensuring uniform FBE epoxy powder melting and consistent coating adhesion. An adjustable spiral pipe conveyor accommodates steel pipe from 325 to 4200 mm, delivering stable throughput of up to 250 m²/h and repeatable fusion bonded epoxy coating quality at 0–6 m/min line speed across every production run. Coating thickness reaches 80–800 μm to match different project specifications.

Equipped with an integrated cyclone and pulse dust collection system plus a closed-loop FBE powder recycling unit, this energy saving coating line meets CE and ISO 14001 environmental protection requirements. Controlled dust emission supports global factory HSE requirements for steel pipe shot blasting and FBE powder coating workshops across Middle East, European, and Central Asian markets.

With nearly 50 completed domestic and overseas coating line projects, Huashida's FBE pipe coating production lines are commissioned and running in Russia, Iran, the UAE, India, Belarus, Kazakhstan, and other international markets. They have earned strong recognition among pipeline fabricators, EPC contractors, and infrastructure developers.

Qingdao Huashida Machinery Co., Ltd., founded in 2003, specializes in R&D and manufacturing of FBE steel pipe anti-corrosion coating equipment, polyurethane pre-insulated pipe production lines, large-diameter underground pipeline machinery, and plastic pipe equipment.
