Product Description

Plastic-coated composite steel pipe

 Plastic-coated composite steel pipe is a new type of composite pipe formed by melting and coating a layer of high-molecular anti-corrosion material on the inner and outer surfaces of high-quality steel pipe through a special process. This product perfectly combines the mechanical strength of steel pipes and the anti-corrosion performance of plastic coatings, and is an upgraded replacement for traditional galvanized steel pipes and plastic pipes.

Advantages: 

1. Excellent Corrosion Resistance: The inner coating effectively resists corrosion from the conveying medium (water, chemicals, etc.); the outer coating resists corrosion from acids, alkalis, and salts in the soil and atmosphere, resulting in a service life far exceeding that of ordinary steel pipe. 2. Excellent Mechanical Strength: The steel base imparts high mechanical strength to the pipe, making it resistant to impact, pressure, and bending, providing high safety performance. 3. Smooth Flow Characteristics: The plastic coating on the inner wall is smooth, offering a low friction coefficient, low conveying resistance, and resistance to scaling, effectively improving conveying efficiency by approximately 30%. 4. Excellent Hygienic Properties: Food-grade epoxy resin and other coatings meet drinking water standards, are non-toxic, odorless, and do not breed microorganisms, making them ideal for water supply and drainage pipes. 5. Easy Installation: A variety of connection methods, including grooves (clamps), flanges, and threads, are available. The installation process is mature and convenient. 6. Strong Weather Resistance: Adapts to harsh environments such as cold and high temperatures, and provides stable performance.

Product structure

Core advantage:

Excellent physical properties:

1. Base steel pipe: High-quality welded steel pipe or seamless steel pipe that complies with standards such as GB/T 3091 and GB/T 8163 shall be adopted 
2. Transition layer: Epoxy resin primer, enhancing adhesion 
3. Anti-corrosion coating Inner coating: Food-grade epoxy resin (EP) or polyethylene (PE) Outer coating: polyethylene (PE), epoxy resin (EP) or polyurethane (PU)

Outstanding anti-corrosion performance The coating is dense and pore-free, isolating the steel pipe from contact with corrosive media Resistant to corrosion by acids, alkalis, salts and various chemical media Suitable for corrosive environments with a pH value of 212 The service life can reach 35 times that of ordinary steel pipes

The coating has strong adhesion (≥30N/10mm) Good impact resistance (≥5J) High compressive strength (up to over 2.5MPa) It has a wide operating temperature range (30℃ to 80℃ Good fluid properties The inner wall is smooth, with a roughness of only 1/10 that of steel pipes It has a low coefficient of friction and small conveying resistance It does not form scale or breed bacteria, ensuring the cleanliness of the fluid The conveying efficiency has been increased by 1520% The comprehensive economic benefits are high Low installation and maintenance costs It has a long service life and a significant cost advantage throughout its entire life cycle Maintenance-free or minimal maintenance, reducing operating costs 

Production process flow 

1. Pretreatment of steel pipes: Sandblasting for rust removal reaches Sa2.5 grade, with a surface roughness of 4080μm
2. Heating treatment: Medium frequency heating to 180-220℃
3. Coating process: Electrostatic spraying or dip coating
4. Curing and shaping: High-temperature curing forms a dense coating 5. Quality inspection: Electrical discharge leak detection, thickness measurement, adhesion testing, etc
