Metallic Zinc Coating
When a metallic zinc spray coating is applied, the average mass of zinc per unit area must be at least 130g/m²,with a minimum local mass of 110 g/m². Custom zinc mass specifications can also be accommodated upon request.
Bitumen Coating
The average bitumen coating thickness must be at least 70 μm, with a local minimum thickness of 50 μm. Custom thickness specifications can also be fulfilled based on customer requirements.
Alternative Coating Options
Process and Testing Procedures:
1. Induction Furnace and Metal Treatment (Includes chemical analysis of raw materials, spheroidizing, and nodularity testing)
2. Casting (Involves visual inspections and weight checks)
3. Heat Treatment (Examines microstructure)
4. Hydrostatic Test (Pressure testing)
5. Dimensional Checks (Verifies pipe length, joint integrity, outer diameter, wall thickness, and appearance)
6. Zinc Spraying (Thickness testing)
7. Lining and Coating (100% visual inspection; random thickness tests)
8. Marking and Packing (100% visual inspection)
