Fire Coated Plastic Steel Pipe | Epoxy Resin Lined Fire Fighting Steel Pipe for Fire Protection System

Fire coated plastic steel pipe is a special composite steel pipe exclusively designed for fire protection systems. It is produced by pretreating the base steel pipe, electrostatically spraying epoxy resin or polyethylene powder on the inner and outer walls, and high-temperature curing to form a tight coating. Strictly manufactured in accordance with national standard GB/T 5135.20-2010 and industry standard CJ/T 120-2016, it meets all performance requirements of fire water supply and sprinkler systems, providing stable and long-term safety guarantee for fire protection projects.

1. Strong Corrosion Resistance
The inner and outer surfaces are covered with epoxy resin or polyethylene coating, which can effectively resist corrosion from water, acid, alkali and other media, extend the service life of the pipe and reduce later maintenance costs.

2. Excellent High Pressure Resistance
With high-strength steel pipe base material and tightly bonded plastic coating, it can bear high water pressure, ensuring stable operation of fire protection systems in emergency fire conditions.

3. Good Fire Retardant Performance
The plastic coating has outstanding flame retardancy, conforms to fire protection standards, and can protect the pipe structure from damage during fire accidents.

4. Smooth Inner Wall & Low Water Flow Resistance
The smooth plastic-lined inner wall reduces water flow resistance greatly, improves water delivery efficiency, and ensures rapid and smooth water supply for fire fighting.

5. Easy Installation & Low Maintenance Cost
It has light weight and multiple connection methods including threaded connection and flange connection. Simple installation procedures cut construction period, and the stable structure keeps low maintenance cost in long-term use.

1. Pretreatment
Derust, clean and dry the steel pipe to ensure the surface free of impurities.

2. Hot Melt Bond Coating
Adopt electrostatic spraying technology to evenly coat epoxy resin powder on the inner and outer surfaces of steel pipe.

3. High-temperature Curing
Send coated steel pipes into high-temperature furnace for curing, making coating tightly combined with steel pipe base material.

4. Quality Inspection
Test finished pipes on appearance, coating thickness, pressure resistance and other indicators to meet standard requirements.

5. Packaging & Transportation
Package qualified products with protective measures to avoid damage during transportation.
