Metallic Zinc Coating
When a metallic zinc spray is applied, the average mass of the zinc per unit area shall be no less than 130g/m².The local minimum can be 110 g/m². Customizable zinc mass according to the client's specifications is available.
Bitumen Coating
The mean thickness of the bitumen coating shall be no less than 70 μm, while the local minimum thickness shall be no less than 50 μm. Customizable bitumen coating thicknesses are available per customer request.
Alternative Coating
Process and Testing:
1. Induction Furnace and Metal Treatment (includes chemical analysis of raw materials, spheroidizing, and nodularity checks)
2. Casting (involves visual inspections and weight checks)
3. Heat Treatment (assessing the microstructure)
4. Hydrostatic Test (conducting pressure tests)
5. Dimensional Checks (including pipe length, joint, outer diameter, wall thickness, and appearance)
6. Zinc Spraying (testing the thickness)
7. Lining and Coating (100% visual inspection with random thickness testing)
8. Marking and Packing (100% visual inspection)
