1. The manufacturing process of 3PE anticorrosive spiral steel pipe.
The manufacturing process of 3PE anticorrosive spiral steel pipe mainly includes the following steps:
1.Steel selection and pretreatment: select high-quality steel, and carry out surface pretreatment to remove impurities such as oil stains and rust on the surface, and ensure the adhesion between the coating and the substrate.
2.Epoxy powder coating: A layer of epoxy powder is coated on the surface of the steel pipe to form an anti-corrosion layer, which has good corrosion resistance and mechanical properties.
3.Adhesive coating: An epoxy powder coating is coated with an adhesive layer to increase the adhesion and abrasion resistance of the coating.
4.Polyethylene anticorrosive layer: A layer of polyethylene anticorrosive layer is extruded or wound on the adhesive coating to further prevent corrosion and waterproofing.
5.Cooling and curing: The coating is cooled and cured at a certain temperature to ensure the stability of the coating.
6.Quality inspection and packaging: The quality inspection of the finished product, including coating thickness, adhesion, corrosion resistance, etc., is carried out after passing the package.
