Metallic Zinc Coating
When the metallic zinc spray is applied, the average zinc mass per unit area must be no less than 130g/m²,with a localized minimum of 110g/m². Zinc mass can be customized based on customer requirements.
Bitumen Coating
The mean thickness of the bitumen coating must be at least 70μm, with a local minimum of 50μm. Bitumen coating thickness can also be customized to meet specific customer needs.
Alternative Coating
Process and Testing:
1. Induction Furnace and Treated Metal (Chemical analysis of raw material, spheroidizing & nodularity)
2. Casting (Visual inspection and weight verification)
3. Heat Treatment (Microstructure analysis)
4. Hydrostatic Test (Pressure testing)
5. Dimensional Checks (Inspection of pipe length and joints, outer diameter, wall thickness, appearance)
6. Zinc Spraying (Thickness inspection)
7. Lining and Coating (100% visual inspection, random thickness testing)
8. Marking and Packing (100% visual inspection)
