Galvanized Coated Pipe Manufacturing Process & Quality Control
How Is Galvanized Coated Pipe Manufactured?
إن galvanization process involves immersing steel pipes in molten zinc to create a protective layer that prevents rust and corrosion. Below is a detailed تفصيل تفصيلي خطوة بخطوة of the manufacturing process:
1. Surface Preparation
- The steel pipes are cleaned using acid pickling to remove rust, scale, and contaminants.
- Pipes are then rinsed and fluxed to enhance the bonding of zinc to the steel surface.
2. Hot-Dip Galvanization Process
- The cleaned pipes are immersed in a molten zinc bath at approximately 450°C (842°F).
- The zinc reacts with the steel to form a corrosion-resistant layer.
3. Cooling & Solidification
- Galvanized pipes are removed from the zinc bath and cooled in water or air.
- The zinc coating hardens, creating a durable, weather-resistant surface.
4. Quality Control & Testing
- Zinc Coating Thickness Testing ensures compliance with ASTM, ISO, and national standards.
- Adhesion Testing verifies that the zinc layer is firmly bonded to the steel.
- Salt Spray & Corrosion Testing assesses rust resistance in harsh environments.
- الاختبار الميكانيكي ensures the pipe maintains structural integrity after galvanization.
5. Final Inspection & Packaging
- الأنابيب visually inspected for uniformity, coating defects, and quality standards.
- كل أنبوب marked with batch numbers, zinc coating specifications, and manufacturer details for full traceability.
- Pipes are then bundled, packed, and prepared for shipping.
