Frequently Asked Questions

Q: What's the difference between internal and external fire pipe coating?

A: External coating protects the pipe from ambient moisture, humidity, and mechanical damage while providing fire code color identification. Internal coating protects from corrosive water, prevents rust scale buildup, and maintains flow capacity. Our modified epoxy formula can do both - external coating via electrostatic spray, internal coating via fluidized bed or internal spray gun.

Q: Why use powder coating instead of liquid paint for fire pipes?

A: Powder coating offers superior performance: (1) Thicker protection - Single coat 60-80μm vs multiple thin paint coats, (2) Better corrosion resistance - No pinholes or weak spots, (3) Faster application - One coat, fast cure, immediate handling, (4) Environmental - Zero VOC, no hazardous waste, (5) Durability - 20+ year service life vs 5-10 years for paint, (6) Lower long-term cost - No repainting needed.

Q: Can this coating be used on galvanized fire pipes?

A: Yes, but galvanized pipes require special surface preparation. The zinc coating must be properly treated with a galvanized metal pretreatment or zinc phosphate to ensure good powder adhesion. Many fire protection contractors prefer non-galvanized pipes with high-quality powder coating as this often provides better long-term corrosion protection at lower cost.

Q: Is your fire protection red coating UV resistant?

A: Yes, we use premium UV-resistant pigments specifically selected for long-term color retention. Our fire protection red maintains its bright, easily identifiable color even after 10+ years of indoor exposure or 5+ years of outdoor exposure. This is critical for fire marshal inspections and emergency response visibility.

Q: What's the minimum order quantity for fire protection red?

A: Fire protection red (RAL 3000) is a stock color with a minimum order of only 200 kg (8 boxes of 25 kg each). This allows fire sprinkler pipe manufacturers and contractors to order economical quantities without large inventory requirements. Custom red shades require 200 kg minimum.

Q: Can this coating be used for underground fire main pipes?

A: Yes, our modified epoxy powder coating provides excellent protection for underground fire main piping. Key factors: (1) Proper surface preparation - Abrasive blasting and zinc phosphate treatment, (2) Adequate film thickness - 80-120μm for underground service, (3) Complete coverage - No holidays or thin spots, (4) Soil conditions - May require additional cathodic protection in extremely corrosive soil.

Q: Is your powder coating safe for drinking water fire systems?

A: Yes, we offer a special potable water grade formulation that meets drinking water safety requirements. This is essential for combined fire/domestic water systems or fire systems that tie into potable water supply. Our drinking water grade powder complies with NSF/ANSI Standard 61 and does not leach harmful substances. Please specify "potable water grade" when ordering.

Q: How do I ensure good internal coating coverage?

A: Internal coating requires specialized equipment and technique: (1) Method selection - Fluidized bed (best), electrostatic internal gun, or preheated pipe dipping, (2) Surface preparation - Critical - internal surface must be completely clean and phosphated, (3) Film thickness - 60-80μm minimum, measure with internal probe, (4) Cure verification - Visual inspection of pipe ends, cut test samples for adhesion. We provide detailed application guidelines and can recommend equipment suppliers.

Q: What causes coating failure in fire sprinkler systems?

A: Main failure causes: (1) Poor surface preparation - Oil residue or inadequate phosphating (80% of failures), (2) Incomplete cure - Under-temperature or short cure time, (3) Contaminated water - Extremely acidic or high-chloride water may require special formulation, (4) Mechanical damage - Improper handling during installation. Prevention: Follow our application guidelines strictly and use proper installation techniques.

Q: Can you provide fire marshal inspection documentation?

A: Yes, we provide complete documentation package: (1) Certificate of Analysis with all test data, (2) Technical Data Sheet with full specifications, (3) MSDS/SDS for safety information, (4) GB/T Test Reports - hardness, adhesion, corrosion, etc., (5) Material composition declaration, (6) RoHS compliance certificate, (7) ISO 9001 certificate. All documentation is suitable for fire marshal inspections and building permits.
