Metallic Zinc Coating
When applying a metallic zinc spray, the mean mass of the zinc per unit area should be at least 130g/m². There is also a local minimum requirement of 110g/m². Custom zinc mass specifications are available upon request.
Bitumen Coating
The mean thickness of the bitumen coating must be at least 70 μm, with a local minimum thickness of no less than 50 μm. Custom bitumen thickness specifications are also available upon request.
Alternative Coating
Process and Testing Protocols:
1. Induction Furnace and Metal Treatment (Includes chemical analysis of raw materials, spheroidizing, and assessing nodularity)
2. Casting (Involves visual inspection and weight verification)
3. Heat Treatment (Analysis of microstructure)
4. Hydrostatic Test (Pressure testing)
5. Dimensional Checks (Assessing pipe length and joints, outer diameter, wall thickness, and overall appearance)
6. Zinc Spraying (Thickness measurement)
7. Lining and Coating (100% visual inspection, with random thickness testing)
8. Marking and Packing (100% visual inspection)
