Metallic Zinc Coating
When applying metallic zinc spray, the average mass of zinc per unit area should be no less than 130g/m²,with a localized minimum of 110g/m². We also provide zinc coatings tailored to meet specific customer requirements.
Bitumen Coating
The average thickness of the bitumen coating must be at least 70 μm, with a localized minimum thickness of no less than 50 μm. Customized bitumen coating thickness is also 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 check)
3. Heat Treatment (Microstructure analysis)
4. Hydrostatic Test (Pressure testing)
5. Dimensional Checks (Length, joint, outer diameter, wall thickness, and appearance inspection)
6. Zinc Spraying (Thickness testing)
7. Lining and Coating (100% visual inspection, random thickness testing)
8. Marking and Packing (100% visual inspection)
