🛠 5. Manufacturing Process
Our GR1 Titanium Tubes are produced using a precise manufacturing sequence:
-
Raw Material Selection – Only top-grade CP titanium billets are sourced.
-
Piercing & Extrusion – Producing a hollow form without seams for maximum integrity.
-
Cold Drawing – Achieving precise OD, wall thickness, and surface finish.
-
Heat Treatment – Stress relief and annealing to restore ductility.
-
Surface Finishing – Acid pickling, bright annealing, or mechanical polishing available.
-
Final Inspection – Dimensional checks, NDT, and certification to ASTM B338 standards.
🧪 6. Quality Control & Testing
Every Seamless GR1 Titanium Tube undergoes rigorous inspection:
-
Chemical Analysis – Ensures compliance with CP titanium purity requirements.
-
Mechanical Testing – Tensile, yield, and elongation verified per ASTM standards.
-
Nondestructive Testing – Ultrasonic or eddy current to detect internal flaws.
-
Dimensional Inspection – Strict tolerances on OD, wall thickness, and straightness.
-
Surface Examination – Visual inspection under magnification to ensure defect-free finish.
🌊 7. Corrosion Resistance Performance
The Commercially Pure Titanium Tube in GR1 exhibits outstanding resistance in:
-
Seawater & Marine Atmospheres – No significant corrosion over decades of service.
-
Chlorinated Water & Brines – Resistant to pitting and crevice attack.
-
Mild Acids & Alkalis – Effective in nitric acid, chromic acid, and alkaline solutions.
-
Oxidizing Environments – Protective oxide film regenerates instantly when damaged.
