Metallic Zinc Coating
When metallic zinc spray is applied, the mean mass of the zinc per unit area shall not be less than 130g/m²,with a local minimum of 110 g/m². Customizable zinc mass is available upon request.
Bitumen Coating
The average thickness of the bitumen coating shall be no less than 70 μm, with a local minimum thickness of no less than 50 μm. Custom thickness specifications are available upon request.
Alternative Coating
Process and Testing:
1. Induction Furnace and Treated Metal (Chemical analysis of raw materials, spheroidizing & nodularity check)
2. Casting (Visual inspection and weight verification)
3. Heat Treatment (Microstructure analysis)
4. Hydrostatic Test (Pressure testing)
5. Dimensional Checks (Pipe length and joint verification, OD, wall thickness, appearance)
6. Zinc Spraying (Thickness verification)
7. Lining and Coating (100% visual inspection, random thickness testing)
8. Marking and Packing (100% visual inspection)
