Metallic Zinc Coating
When applying metallic zinc spray, the average mass of zinc per unit area must not be less than 130g/m²,with a local minimum of 110g/m². We also offer customization of the zinc mass according to customer specifications.
Bitumen Coating
The average thickness of the bitumen coating must be at least 70 μm, with a local minimum of 50 μm. Customization of bitumen coating thickness according to the customer's requirements is also available.
Alternative Coating
Process and Testing:
1. Induction Furnace and Treated Metal: Conduct chemical analysis of raw materials, spheroidizing, and nodularity checks.
2. Casting: Perform visual inspections and weight checks.
3. Heat Treatment: Examine the microstructure.
4. Hydrostatic Test: Conduct pressure tests.
5. Dimensional Checks: Measure pipe length, joint, outer diameter, wall thickness, and appearance.
6. Zinc Spraying: Test thickness.
7. Lining and Coating: Perform 100% visual inspections and random thickness tests.
8. Marking and Packing: Ensure 100% visual inspections.
