How to Protect Flanges During Painting

Painting is a critical step in protecting piping systems, valves, and equipment from corrosion and environmental damage. However, painting processes can expose sensitive flange faces and pipe interiors to overspray, debris, and contamination that may compromise sealing surfaces and system integrity.

At Precision Piping Products, we offer specialized protection products designed to safeguard your piping assets during all painting stages — from surface preparation to final coating. Our solutions help maintain flange face quality, prevent internal contamination, and reduce rework and downtime.

Common Challenges During Painting

• Protecting flange sealing surfaces: Paint overspray or debris on flange faces can interfere with gasket sealing, leading to leaks and costly repairs.
• Preventing internal contamination: Paint, dust, or debris entering pipe interiors can clog systems or damage equipment downstream.
• Avoiding physical damage: Handling during painting operations may cause scratches or dents on exposed surfaces.
• Ensuring easy removal: Protective products must prevent contamination but also be simple to remove without leaving residue or damaging coatings.

Our Painting Protection Solution

flangeDOTS®

• ANSI-rated peel-and-stick protective dots designed specifically to protect flange sealing surfaces during painting.
• Precision cut and easily removed without leaving any residue.
• Available with VCI (Vapor Corrosion Inhibitor) technology to prevent corrosion.
• Simple to apply, saving time and labor compared to traditional protection methods.

Best Practices for Painting Protection

• Pre-paint inspection: Verify all flangeDOTS® are properly applied and flange faces are clean before painting begins.
• Choose the right product: Use flangeDOTS® appropriate for your flange size and painting method.
• Careful handling: Minimize handling damage by keeping protected components covered until painting is complete.
• Post-paint clean-up: Remove flangeDOTS® carefully to avoid damaging coatings or leaving residues on sealing surfaces.
