1. Preparation process.
The preparation process of winding 3PE anticorrosive longitudinal seam steel pipe mainly includes steel pipe pretreatment, primer coating, middle coating, topcoat coating and winding reinforcement layer.
1.Steel pipe pretreatment: First of all, the steel pipe needs to be derusted, cleaned and dried to ensure the adhesion of the coating.
2.Primer coating: Primer is an important part of anti-corrosion coating, generally using epoxy coal asphalt paint or polyurethane paint, etc., which has excellent anti-corrosion performance and adhesion.
3.Intermediate coating: The intermediate coating is generally made of polyethylene or polypropylene and other materials, which have good permeation resistance and chemical corrosion resistance.
4.Topcoat coating: Topcoat is the last layer of anti-corrosion coating, generally using materials such as polyolefin, which has excellent weather resistance and UV resistance.
5.Winding reinforcement layer: In order to improve the mechanical strength and service life of the pipe, a reinforcement layer is usually wound on the outside of the anti-corrosion coating, generally using materials such as polyester fiber or glass fiber.
Second, performance characteristics.
Spiral wound 3PE anti-corrosion longitudinal seam steel pipe has the following performance characteristics:
1.Excellent anti-corrosion performance: The use of advanced anti-corrosion coating materials and preparation processes can effectively prevent the corrosion and damage of steel pipes in harsh environments.
2.Good mechanical strength: The steel pipe itself has high mechanical strength, and the reinforcing layer on the outside of the anti-corrosion coating can also improve the pressure bearing capacity and impact resistance of the pipe.
3.Good weather resistance and chemical corrosion resistance: The anti-corrosion coating has good weather resistance and chemical resistance, and can adapt to various harsh environments and use scenarios.
4.Easy to install and maintain: The steel pipe adopts a longitudinal seam welding process, which is easy to install, and the anti-corrosion coating has good wear resistance and scratch resistance, which is easy to maintain.
