Polyurethane Coated Pipe Manufacturing Process & Quality Control

How Is Polyurethane Coated Pipe Manufactured?

The polyurethane coating process involves applying a high-performance polyurethane material onto the steel pipe surface. This results in a durable, corrosion-resistant, and thermally insulated layer. Below is a breakdown of the step-by-step Polyurethane Coated Pipe manufacturing process:

1. Surface Preparation

• The steel pipe is cleaned using shot blasting or sandblasting to remove rust, scale, and contaminants.
• The surface is roughened to ensure strong adhesion of the polyurethane coating.

2. Application of Polyurethane Coating

• A liquid polyurethane material is applied using spray coating or dip coating techniques.
• The coating is applied in multiple layers, depending on the required thickness and project specifications.
• The polyurethane material hardens into a dense, protective layer, preventing corrosion and thermal loss.

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 remains durable, flexible, and resistant to cracking.

4. Quality Control & Testing

• Coating Thickness Measurement ensures the required thickness is achieved.
• Adhesion Testing verifies the bond strength between the coating and steel surface.
• Thermal Insulation Testing evaluates the coating’s performance in heat retention applications.
• Corrosion Resistance Testing assesses long-term durability in harsh environments.

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 Polyurethane Coated Pipes Are Preferred?

✔ Superior resistance to corrosion, moisture, and extreme temperatures
✔ Excellent thermal insulation for district heating and oil pipelines
✔ Longer lifespan compared to traditional coatings
✔ Ideal for underground, industrial, and offshore applications
