Compliance Standards:

GB/T 5135.20-2010; CJ/T 120-2008 Application Fields:

Anti-corrosion coating for internal and external surfaces of water supply pipes used in firefighting.

Application Processes:

Spraying, dip coating, etc.

Precautions:

The steel pipe surface should be free of oil and moisture; the surface treatment quality should reach Sa2 1/2 level (GB/T 8923); the anchor pattern depth should be 50-90 mm; dust and abrasives on the steel pipe surface should be blown clean.

Preheating temperature should be controlled between 180-240°C.

The product should be stored in a well-ventilated, dry indoor environment with a temperature below 30°C, away from heat sources, corrosive chemicals, and chemical solvents, and protected from strong light exposure.

The stacking height should not exceed four layers.

Avoid long-term pressure and ensure the packaging box is sealed to prevent caking and moisture, which can affect fluidization performance.

To ensure thorough curing of the epoxy coating and better anti-corrosion performance, it is recommended to preheat the steel pipe surface to above 200°C to improve the curing completion rate.
