Bitumen Coating
The mean thickness of the bitumen coating shall not be less than 70 μm and the local minimum thickness shall not be less than 50 μm. The thickness can be customized as per customer requests.
Alternative Coating
Process and Testing:
1. Induction furnace and treated metal (Chemical analysis of raw material, spheroidizing & Nodularity)
2. Casting (Visual check and weight check)
3. Heat treatment (Microstructure analysis)
4. Hydrostatic test (Pressure testing)
5. Dimensional checks (Examining pipe length, joint, OD, wall thickness, and overall appearance)
6. Zinc spraying (Thickness verification)
7. Lining and coating (100% visual inspection with random thickness testing)
8. Marking and packing (100% visual inspection)
