Glass Flake Coated Pipe Manufacturing Process & Quality Control

How Is Glass Flake Coated Pipe Manufactured?

The glass flake coating process involves applying high-performance resin mixed with glass flakes onto the steel pipe surface. This creates a dense, impermeable barrier that enhances corrosion resistance, chemical protection, and mechanical durability. Below is a detailed step-by-step breakdown of the Glass Flake Coated Pipe manufacturing process:

1. Surface Preparation

• The steel pipe is cleaned using shot blasting or sandblasting to remove rust, scale, and contaminants.
• A roughened surface is created to improve adhesion of the glass flake coating.

2. Application of Glass Flake Coating

• A high-performance resin mixed with glass flakes is applied using airless spray techniques.
• The coating is applied in multiple layers, depending on the required thickness and project specifications.
• The glass flakes form overlapping layers, creating an impermeable barrier against corrosion.

3. Curing & Hardening

• The coated pipes are cured in a controlled environment to ensure proper hardening and chemical bonding.
• This step guarantees that the coating maintains its durability, flexibility, and resistance to cracking.

4. Quality Control & Testing

• Coating Thickness Measurement ensures the required film thickness is achieved.
• Adhesion Testing verifies the bond strength between the coating and steel surface.
• Salt Spray & Corrosion Resistance Testing assesses long-term durability in harsh environments.
• Impact Resistance Testing ensures the coating can withstand mechanical stress.

5. Final Inspection & Packaging

• Pipes are visually inspected for uniformity, coating defects, and quality standards.
• Each pipe is marked with batch numbers, coating specifications, and manufacturer details for full traceability.
• Pipes are then bundled, packed, and prepared for shipping.

Why Glass Flake Coated Pipes Are Preferred?

✔ Superior resistance to corrosion, seawater, and harsh chemicals
✔ Longer lifespan compared to conventional coatings
✔ Ideal for offshore, oil & gas, and industrial applications
✔ Reduces maintenance and replacement costs
