Manufacturing Process
| Stage | Process |
|---|---|
| 1. Material Selection | Cold-rolled 304 Stainless Steel coils or precision flat strips |
| 2. Forming | Roll forming or TIG welding into sharp-edged square profiles |
| 3. Heat Treatment | Solution annealing for improved corrosion resistance |
| 4. Surface Treatment | Pickling, passivation, or polishing for a clean, durable finish |
| 5. Quality Control | Hydrostatic testing, dimensional checks, and chemical composition analysis |
Each pipe undergoes rigorous inspection and testing to ensure uniform thickness, consistent hardness, and compliance with international standards. We also support custom laser marking and barcode tagging for easy warehouse tracking.
