Metallic Zinc Coating
When a metallic zinc spray is applied, the average mass of zinc per unit area will not be less than 130g/m²,with a localized minimum of 110g/m². Custom zinc mass specifications are also available upon request.
Bitumen Coating
The average thickness of the bitumen coating shall not be less than 70 μm, with a localized minimum thickness of at least 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)
2. Casting (Visual inspection and weight verification)
3. Heat Treatment (Microstructure analysis)
4. Hydrostatic Test (Pressure testing)
5. Dimensional Checks (Verification of pipe length, joint, OD, wall thickness, and appearance)
6. Zinc Spraying (Thickness testing)
7. Lining and Coating (100% visual inspection, and random thickness testing)
8. Marking and Packing (100% visual inspection)
