Products Details
GR1 Titanium Capillary Tube
(Suitable for ultra-low pressure precision molding)
Core Advantages: Good ductility (elongation 28%); no risk of brittle fracture; biocompatibility is better than other pure titanium grades and it is non-allergenic.
GR2 Titanium Capillary Tube
(Suitable for low-pressure and high-cleanliness)
Core Advantages: Easy to clean; corrosion-resistant, no rust after long-term use; lower cost than alloy grades.
GR5 Titanium Capillary Tube
(Suitable for high-pressure and harsh environment)
Core Advantages: Resistant to strong acids (such as hydrochloric acid and sulfuric acid), oil and gas corrosion, no leakage risk; resistant to vibration fatigue and long service life.
GR9 Titanium Capillary Tube
(Suitable for Installation in Harsh Environments)
Core Advantages: The strength of the welded joint is more than 95% of the parent material and can be seamlessly welded into a piping system; it has excellent toughness in a -196℃ liquid nitrogen environment and has no cracking risk.

Frequently Asked Questions (FAQ)
Q: What is the main difference between GR1 and GR2 titanium capillary tubes?
GR1 titanium offers superior ductility (with an elongation of 28%) and is excellent for ultra-low pressure precision molding and medical biocompatibility. GR2 titanium is ideal for low-pressure, high-cleanliness applications, offering easy cleaning and corrosion resistance at a lower cost.
Q: Why should I choose GR5 titanium capillary tubes for harsh environments?
GR5 titanium (Ti-6Al-4V) features high tensile strength (895MPa), outstanding fatigue resistance, and strong resistance to acids (like hydrochloric and sulfuric acids) and oil/gas corrosion, making it perfect for high-pressure, extreme environments.
Q: What are the typical applications for GR2 titanium tubes in the food industry?
Due to its high cleanliness and corrosion resistance, GR2 titanium capillary tubes are widely used in food processing for aseptic feeding pipes in dairy production lines and quantitative delivery pipes for beverage filling equipment.
Q: How does GR9 titanium perform in extreme temperatures?
GR9 titanium capillary tubes exhibit excellent toughness even in extremely cold environments, such as a -196℃ liquid nitrogen environment, without any risk of cracking. They also allow for seamless welding with joint strength exceeding 95% of the parent material.
Q: Are these titanium capillary tubes biocompatible?
Yes, pure titanium grades like GR1 offer exceptional biocompatibility, which is superior to other titanium grades, making them non-allergenic and highly suitable for sensitive precision applications.
