Process and Testing Protocols:
1. Induction furnace and treated metal (Including chemical analysis of raw material, spheroidizing, and nodularity).
2. Casting (Includes visual inspection and weight check).
3. Heat treatment (Microstructural analysis).
4. Hydrostatic test (Pressure assessment).
5. Dimensional checks (Verification of pipe length, joint, OD, wall thickness, and overall appearance).
6. Zinc spraying (Thickness verification).
7. Lining and coating (100% visual inspection, random thickness testing).
8. Marking and packing (100% visual inspection).
