Process and Testing Protocols:
1. Induction Furnace and Metal Treatment (Includes chemical analysis of raw materials, spheroidizing, and assessing nodularity)
2. Casting (Involves visual inspection and weight verification)
3. Heat Treatment (Analysis of microstructure)
4. Hydrostatic Test (Pressure testing)
5. Dimensional Checks (Assessing pipe length and joints, outer diameter, wall thickness, and overall appearance)
6. Zinc Spraying (Thickness measurement)
7. Lining and Coating (100% visual inspection, with random thickness testing)
8. Marking and Packing (100% visual inspection)
