Process and Testing:
1. Induction Furnace and Treated Metal (Includes thorough chemical analysis of raw materials, spheroidizing, and nodularity inspection).
2. Casting (Encompasses visual and weight checks to ensure product integrity).
3. Heat Treatment (Ensures optimal microstructure quality).
4. Hydrostatic Test (Rigorous pressure testing for maximum reliability).
5. Dimensional Checks (Meticulously checking pipe length, joint, outer diameter, wall thickness, and overall appearance).
6. Zinc Spraying (Precision thickness testing to guarantee coating consistency).
7. Lining and Coating (100% visual inspection and random thickness testing for assured quality).
8. Marking and Packing (Ensuring 100% visual checks for perfect presentation).
