Metallic Zinc Coating
When a metallic zinc spray is applied, the average mass of zinc per unit area must not be less than 130g/m², ensuring durable and robust protection.A local minimum of 110g/m² is acceptable, offering flexibility based on customer requirements.
Bitumen Coating
The average thickness of the bitumen coating should be at least 70μm, with a local minimum thickness of no less than 50μm. Custom thickness options are available to meet specific client needs.
Alternative Coating
Process and Testing:
1. Induction Furnace & Treated Metal: Chemical analysis of raw materials, spheroidizing, and nodularity testing ensure superior product quality.
2. Casting: Each piece undergoes a rigorous visual check and weight verification to maintain consistency.
3. Heat Treatment: Microstructure analysis guarantees optimal strength and durability.
4. Hydrostatic Test: Pressure tests confirm the pipe's ability to withstand operational stress.
5. Dimensional Checks: We verify pipe length, joint integrity, outer diameter, wall thickness, and overall appearance to meet precise standards.
6. Zinc Spraying: Thickness testing ensures a uniform protective coating.
7. Lining and Coating: 100% visual inspection and random thickness testing guarantee top-notch quality.
8. Marking and Packing: Each product undergoes a final visual inspection before marking and packing.
