Detailed Process and Testing Procedures:
1. Induction furnace and treated metal (Conduct chemical analysis of raw materials, spheroidizing, and checking nodularity)
2. Casting (Includes visual checks and weight verifications)
3. Heat Treatment (Examine microstructure)
4. Hydrostatic Test (Perform pressure testing)
5. Dimensional Checks (Measure pipe length, joint, outer diameter, wall thickness, and appearance)
6. Zinc Spraying (Perform thickness testing)
7. Lining and Coating (100% visual check and random thickness testing)
8. Marking and Packing (Ensure 100% visual check)
