Frequently Asked Questions
What are the main grades of titanium capillary tubes?
The primary grades include GR1, GR2, GR5, and GR9. Each grade offers distinct mechanical properties suitable for applications ranging from high-precision molding to high-pressure aviation systems.
Which titanium grade is best for medical or food applications?
GR1 and GR2 are highly recommended for medical and food applications due to their exceptional biocompatibility, non-allergenic properties, and resistance to corrosion, ensuring compliance with strict hygiene standards.
How does GR5 titanium capillary tubing handle harsh environments?
GR5 (Ti-6Al-4V) is a high-strength titanium alloy. It features a tensile strength of 895MPa, excellent fatigue resistance, and resistance to strong acids like hydrochloric and sulfuric acid, making it ideal for downhole oil and gas extraction.
Why is GR9 titanium tubing preferred for welded piping systems?
GR9 titanium capillary tubes maintain over 95% of the parent material's strength at the welded joint. This allows them to be seamlessly welded without the risk of cracking, even in extreme conditions down to -196°C.
Are these titanium capillary tubes resistant to vibration fatigue?
Yes, especially alloy grades like GR5 and GR9. Their high tensile strength and structural integrity ensure a long service life and prevent leakage risks under continuous vibration fatigue.
