Pipeline asphalt paint / Pipeline asphalt coating

Crown Brand Paint - Pipeline Asphalt Paint (Pipeline Asphalt Coating), custom paint orders 152^0825^6966 Manager Sun, available for supply in Sichuan, Chengdu, Yunnan, and other regions. Pipeline asphalt paint is a specialized coating designed for pipeline anti-corrosion, primarily composed of asphalt as the base, with added modified materials, solvents, and anti-corrosion fillers.

Main Types
Petroleum Asphalt Paint: Traditional type, strong water resistance, low cost, but poor temperature and weather resistance.

Coal Tar Asphalt Paint: Excellent anti-corrosion performance (especially resistant to acids, alkalis, and microorganisms), commonly used for underground or underwater pipelines, but with poor environmental friendliness.

Modified Asphalt Paint: Added resins such as epoxy and polyurethane to enhance mechanical properties, adhesion, and temperature resistance (e.g., -30°C to 80°C).

Product Characteristics
Anti-corrosion: Isolates moisture and oxygen, resists erosion from soil and chemical media.

Insulation: Possesses certain electrical insulation properties, aiding in the prevention of electrochemical corrosion.

Flexibility: Adapts to thermal expansion, contraction, or minor deformations of pipelines, reducing the risk of cracking.

Easy Application: Can be applied by brushing, spraying, or dipping, cures at room temperature, suitable for field operations.

Application Scenarios
Underground Pipelines: Such as municipal water supply and drainage pipes, resisting corrosion from soil and groundwater.

Subsea Pipelines: Coal tar asphalt paint is commonly used in marine environments.

High-Temperature Pipelines: Modified asphalt paint (e.g., epoxy asphalt) is used for the external walls of oil pipelines.

Temporary Protection: Used as a short-term anti-rust coating during maintenance.

Key Construction Points
Surface Preparation: Requires thorough rust removal and cleaning (meeting Sa2 or St3 standards).

Complementary Coatings: Often used in combination with fiberglass cloth to enhance the strength of the protective layer.

Environmental Limitations: Avoid application during rain or snow; some types require ventilation and explosion-proof measures.
