- Desalination Plants: Evaporator tubes and brine heaters.
- Oil & Gas: Offshore platform piping, subsea equipment.
- Power Generation: Condenser tubes, heat exchangers.
7. Manufacturing Process
- Material Selection: High-purity electrolytic copper and nickel.
- Forming: Cold-drawn seamless process ensures uniform wall thickness.
- Heat Treatment: Annealing to optimize ductility and stress relief.
- Surface Finish: Pickling, passivation, and hydraulic testing (ASTM E165).
8. Quality Assurance
- NDT Testing: 100% ultrasonic (UT) and eddy current (ET) inspection per ASTM E213/E309.
- Dimensional Check: Laser measurement for OD, ID, and wall thickness.
- Certification: Mill Test Certificate (MTC) with traceable heat number.
9. Packaging & Delivery
- Packaging: Wooden crates with anti-rust oil coating and PVC end caps.
- Shipping: Seaworthy export packaging compliant with IMDG/IMO regulations.
