Process and Testing Procedures:
1. Induction Furnace and Treated Metal: Involves chemical analysis of raw materials, spheroidizing, and verifying nodularity.
2. Casting: Includes visual inspection and weight verification to ensure quality.
3. Heat Treatment: Examines the microstructure to guarantee material integrity.
4. Hydrostatic Test: Conducts pressure testing for durability.
5. Dimensional Checks: Measures pipe length, joint OD, wall thickness, and overall appearance.
6. Zinc Spraying: Performs thickness testing to ensure proper coating.
7. Lining and Coating: Involves 100% visual inspection and random thickness testing.
8. Marking and Packing: Ensures a 100% visual check for quality.
