Metallic Zinc Coating
When metallic zinc spray is applied, the average mass of the zinc per unit area shall be not less than 130g/m², ensuring superior protection and longevity.This coating includes a local minimum of 110 g/m², providing flexibility to meet customer-specific requirements.
Bitumen Coating
The average thickness of the bitumen coating shall be not less than 70 μm, with a local minimum thickness of at least 50 μm. Custom thicknesses are available to suit specific customer needs.
Alternative Coating
Process and Testing:
1. Induction Furnace and Treated Metal (including chemical analysis of raw materials, spheroidizing, and nodularity)
2. Casting (comprehensive visual and weight checks)
3. Heat Treatment (examination of microstructure)
4. Hydrostatic Test (pressure testing)
5. Dimensional Checks (assessing pipe length, joint accuracy, outer diameter, wall thickness, and overall appearance)
6. Zinc Spraying (thorough thickness testing)
7. Lining and Coating (100% visual inspection and random thickness testing)
8. Marking and Packing (100% visual inspection)
