Metallic Zinc Coating
When applying the metallic zinc spray, the average zinc mass per unit area shall not be less than 130g/m².A local minimum of 110 g/m² is acceptable. Custom zinc mass specifications are also available upon request.
Bitumen Coating
The mean thickness of the bitumen coating shall be no less than 70 μm, with a local minimum thickness of 50 μm. Custom thickness specifications can be provided upon request.
Alternative Coating
Process and Testing:
1. Induction furnace and treated metal (Chemical analysis of raw materials, spheroidizing & Nodularity)
2. Casting (Visual inspection and weight verification)
3. Heat treatment (Microstructure assessment)
4. Hydrostatic test (Pressure testing)
5. Dimensional checks (Verification of pipe length and joint, outer diameter, wall thickness, and appearance)
6. Zinc spraying (Thickness measurement)
7. Lining and coating (100% visual inspection and random thickness testing)
8. Marking and packing (100% visual inspection)
