Metallic Zinc Coating
When a metallic zinc spray is applied, the average mass of zinc per unit area shall be no less than 130g/m², ensuring robust protection.A local minimum of 110 g/m² is also maintained for added reliability. Custom zinc mass specifications are available upon request.
Bitumen Coating
The bitumen coating boasts an average thickness of at least 70 μm, with a local minimum thickness not falling below 50 μm, delivering enduring durability. Custom thickness options are available as per customer requirements.
Alternative Coating
Process and Testing:
1. Induction furnace and treated metal (including chemical analysis of raw materials, spheroidizing, and nodularity testing)
2. Casting (visual inspections and weight checks)
3. Heat treatment (examination of microstructure)
4. Hydrostatic test (pressure testing)
5. Dimensional checks (verification of pipe length, joint, outer diameter, wall thickness, and overall appearance)
6. Zinc spraying (thickness testing)
7. Lining and coating (100% visual inspection and random thickness checks)
8. Marking and packing (100% visual inspection)
