The structure and production process of Anti-Corrosion Spiral Steel Pipe

1. 3PE anti-corrosion steel pipe anti-corrosion structure:
The first layer of epoxy powder (FBE>100um)
The second layer of adhesive (AD) 170-250um

The third layer of polyethylene ((PE) 1.8 ~ 3.7mm (common grade ~ reinforced grade)

The three materials are integrated and firmly combined with the steel pipe to form an excellent anti-corrosion layer. In actual operation, the three materials are mixed and integrated, and after processing, they are firmly combined with the steel pipe to form an excellent anti-corrosion layer. Its processing methods are generally divided into two types: winding type and round mold coating type.

Anti-Corrosion Spiral Steel Pipe coating (three-layer polyethylene anti-corrosion coating) is a new anti-corrosion coating produced by cleverly combining the European 2PE anti-corrosion coating and the epoxy powder anti-corrosion steel coating (FBE) widely used in North America. Steel pipe coating. It has been recognized and used all over the world for more than ten years.

The coating of the Anti-Corrosion Spiral Steel Pipe is an epoxy powder anti-corrosion coating that is in contact with the bottom layer and the steel pipe surface, and the middle layer is a copolymerized adhesive with branched functional groups. The surface layer is high-density polyethylene anti-corrosion coating.

3PE anti-corrosion coating combines the high impermeability and high mechanical properties of epoxy resin and polyethylene materials. So far, it is recognized globally as the pipeline anti-corrosion coating with the best effect and performance, so it has been applied in many projects. It has good anti-corrosion performance, low water absorption, high mechanical strength and other properties. In recent years, it has been more and more widely used in domestic buried water, gas and oil pipelines.

2. Product specifications:
89mm- 1820mm, wall thickness 6mm-20mm

3. Material:
Q235B, Q345B, 10# steel, 20# steel, X42-X80 grade, etc.

4. Implementation standards:
GB/T23257-2009 "Technical Standard for Buried Steel Pipeline Polyethylene Anticorrosion Coating", SY/T0413-2002 "Technical Standard for Buried Steel Pipeline Polyethylene Anticorrosion Coating", DIN30670-91 German "Polyethylene Coating for Steel Pipes and Fittings" Layer technical standard", CAN/CSA-7245.21-M92 Canada "Technical standard for polyethylene anti-corrosion coating on outer wall of steel pipe"

5. Use:
Anti-Corrosion Spiral Steel Pipe are widely used in oil pipelines, natural gas pipelines, heating pipelines, and water supply pipelines.
6.Process flow of 3pe anti-corrosion steel pipe:
The first step is to sandblast and derust the outer wall of the base pipe, and move to the winding station after the sandblasting is completed.
The second step is to use intermediate frequency equipment to heat the steel pipe.
The third step is to spray the first layer of epoxy powder. Check the temperature.
The fourth step is to roll the second layer of adhesive.
The fifth step is to wrap the third layer of polyethylene (PE).
The sixth step is to spray water on the steel pipe for cooling and heat dissipation.
The seventh step is to move the wound 3PE steel pipe to the grinding machine position, and grind the welded joint.
