Frequently Asked Questions (FAQ)
1. What are the key advantages of GR1 Titanium Capillary Tubes?
GR1 Titanium Capillary Tubes offer excellent ductility with an elongation of 28%, eliminating the risk of brittle fracture. Additionally, they feature superior biocompatibility compared to other pure titanium grades and are entirely non-allergenic, making them ideal for precision medical and ultra-low pressure applications.
2. In which industries are GR2 Titanium Capillary Tubes most commonly used?
GR2 Titanium Capillary Tubes are highly recommended for low-pressure and high-cleanliness environments. Common applications include the food industry (such as aseptic feeding pipes for dairy production lines and delivery lines for beverage filling equipment) due to their easy-to-clean, corrosion-resistant, and rust-free properties.
3. Why is GR5 titanium preferred for high-pressure and harsh environments?
GR5 titanium (Ti-6Al-4V) features an exceptionally high tensile strength of 895MPa. It provides outstanding resistance to vibration fatigue, strong acids (like hydrochloric and sulfuric acid), and oil or gas corrosion, ensuring a long, leak-free service life under extreme conditions.
4. What makes GR9 Titanium Capillary Tubes suitable for extreme low-temperature installations?
GR9 Titanium Capillary Tubes maintain excellent toughness and structural integrity even in liquid nitrogen environments as cold as -196℃, without any risk of cracking. Furthermore, their welded joints retain over 95% of the parent material's strength, enabling seamless integration into complex piping systems.
5. How do GR1 and GR5 titanium grades compare in tensile strength?
GR1 is a pure titanium grade (≥99.6% purity) with a tensile strength of 240MPa, offering high ductility and ease of bending. GR5 is an alloyed titanium (Ti-6Al-4V) with a much higher tensile strength of 895MPa, engineered specifically for high-stress and high-fatigue industrial applications.
