Frequently Asked Questions (FAQ)

What are the key benefits of using GR1 Titanium Capillary Tubes?

GR1 titanium capillary tubes offer excellent ductility with a 28% elongation rate, eliminating the risk of brittle fracture. Additionally, they provide superior biocompatibility compared to other pure titanium grades and are entirely non-allergenic, making them perfect for ultra-low pressure precision molding.

Why is GR2 Titanium preferred for the food industry?

GR2 titanium capillary tubes are highly suitable for low-pressure, high-cleanliness applications like food and beverage production. They are easy to clean, highly corrosion-resistant (preventing rust over long-term use), and offer a more cost-effective solution compared to titanium alloy grades.

How does GR5 Titanium perform in high-pressure and harsh environments?

GR5 titanium capillary tubes are engineered for extreme environments. With a tensile strength of 895MPa, they resist strong acids (such as hydrochloric and sulfuric acids) as well as oil and gas corrosion. They also resist vibration fatigue, ensuring zero leakage risk and a long service life.

What are the welding characteristics of GR9 Titanium Capillary Tubes?

GR9 titanium capillary tubes can be seamlessly welded into complex piping systems, with the welded joint maintaining over 95% strength of the parent material. They also exhibit outstanding toughness in extreme conditions, such as -196℃ liquid nitrogen environments, with no risk of cracking.

How do GR1 and GR5 titanium grades differ in mechanical strength?

GR1 is a pure titanium grade (≥99.6% Ti) with a tensile strength of 240MPa, offering high plasticity and easy bending for low-pressure uses. In contrast, GR5 is an alloy grade (Ti-6Al-4V) with a much higher tensile strength of 895MPa, optimized for high pressure, fatigue resistance, and harsh operating conditions.
