Frequently Asked Questions (FAQ)
What are the primary differences between GR1 and GR2 titanium capillary tubes?
GR1 titanium capillary tubes offer exceptional ductility (28% elongation) and biocompatibility, making them ideal for ultra-low pressure precision molding. GR2 tubes are corrosion-resistant and highly cost-effective, perfect for low-pressure and high-cleanliness environments.
Why is GR5 titanium preferred for harsh environments?
GR5 (Ti-6Al-4V) is a high-strength alloy (895MPa tensile strength) that is highly resistant to strong acids, vibration fatigue, and oil/gas corrosion, eliminating the risk of leakage in demanding applications.
Can GR9 titanium capillary tubes be welded reliably?
Yes, GR9 titanium capillary tubes can be seamlessly welded into piping systems. The strength of the welded joint exceeds 95% of the parent material, ensuring leak-free performance even in extreme environments down to -196℃.
What industries commonly use GR2 titanium capillary tubes?
GR2 tubes are widely utilized in the food and beverage industry, specifically for aseptic feeding pipes in dairy production lines and quantitative delivery pipes in beverage filling equipment.
Are titanium capillary tubes biocompatible?
Yes, pure titanium grades like GR1 offer exceptional biocompatibility that is superior to other titanium grades, ensuring they are non-allergenic and safe for sensitive applications.
