Metallic zinc coating
When metallic zinc spray is applied, the mean mass of the zinc per unit area shall be not less than 130g/m2,with a local minimum of 110 g/m2. Custom zinc mass specifications can also be accommodated upon request.
Bitumen coating
The mean thickness of the bitumen coating shall be no less than 70 μm, with a local minimum thickness of at least 50 μm. Custom bitumen coating thickness is also available upon request.
Alternative coating
Process and Testing:
1. Induction furnace and treated metal (includes chemical analysis of raw material, spheroidizing & nodularity testing)
2. Casting (includes visual inspection and weight verification)
3. Heat treatment (microstructure analysis)
4. Hydrostatic test (pressure testing)
5. Dimensional checks (inspection of pipe length and joint, outer diameter, wall thickness, and appearance)
6. Zinc spraying (thickness testing)
7. Lining and coating (100% visual inspection, with random thickness testing)
8. Marking and packing (100% visual inspection)
