High Quality Gr2 Titanium Pipe

Gr2 titanium tube is all industrial pure titanium, they have high mechanical properties, excellent stamping performance, and can perform various forms of welding, the strength of the welded joint can reach 90% of the strength of the base metal, and the cutting performance is good.

1. Exceptional corrosion resistance, capable of withstanding harsh environments

The surface of Gr2 titanium tubes naturally forms a dense, stable oxide film, providing exceptional corrosion resistance and the ability to withstand erosion from a wide range of complex media. Its applications far exceed those of traditional metal tubes such as Stainless Steel:

- Resistance to seawater and salt spray corrosion: The corrosion rate after 30 years of full immersion in seawater is <0.0005 mm/year, making it suitable for marine engineering, seawater desalination, and other applications, with a service life 3–5 times longer than that of stainless steel;

- Resistance to acids, alkalis, and chemical media: Withstands 65% boiling nitric acid, sodium hypochlorite solutions, and wet chlorine gas, among others, without pitting or stress corrosion cracking, making it suitable for the chemical, chlor-alkali, and pharmaceutical industries;

- Sanitary-grade corrosion resistance: No migration of metal ions; complies with food contact standards such as FDA 21 CFR 177.2600; suitable for sanitary applications such as food brewing and dairy processing.

2. Excellent Mechanical Properties, Lightweight and Durable

Thanks to its optimal chemical composition, Gr2 titanium tubing offers the core advantages of being lightweight yet high-strength. Its mechanical properties far exceed those of ordinary metal tubing, and it also boasts excellent machinability:

- Balance of strength and toughness: In the annealed state, tensile strength ≥ 345 MPa, yield strength ≥ 275 MPa, and elongation ≥ 20%, making it suitable for light to medium-load applications with minimal risk of deformation or fracture;

- Lightweight and efficient: With a density of only 4.51 g/cm³, it is 40% lighter than steel and 50% lighter than copper alloys, significantly reducing the overall weight of equipment while improving installation efficiency and energy consumption performance;

- Easy to Process and Form: Possesses excellent ductility, weldability, and cold working properties, enabling various processing techniques such as bending, flaring, deep drawing, and welding. It accommodates complex piping designs, requires no additional heat treatment after welding, and maintains a toughness in the welded area of over 85% that of the base material.

3. Suitable for All Applications, Versatile Across Industries

Thanks to its combined advantages of corrosion resistance, strength, and machinability, Gr2 titanium tubing is used in over 10 core industries. It can adapt to various operating conditions without requiring specific modifications, making it the most widely used grade of industrial pure titanium:

- Chemical and Petrochemical Industries: Heat exchanger tubes, reactors, acid and alkali transport pipelines, chlor-alkali industrial equipment, etc. It resists chemical medium corrosion and extends equipment service life to over 30 years;

- Marine and Environmental Protection: Seawater desalination equipment, ship condensers, marine aquaculture cages, wastewater treatment pipelines, etc. It exhibits outstanding resistance to seawater corrosion and is suitable for harsh offshore environments;

- Energy and Power: Geothermal well heat exchangers, nuclear power plant coolers, LNG cryogenic pipelines, power plant condensers, etc. It withstands high temperatures and high-salinity brine corrosion, ensuring stable equipment operation;

FAQ

1. What is the difference between Gr2 titanium tubing and Gr1 and Gr3 titanium tubing?

All three are industrial grade pure Titanium Material, but the key differences lie in their oxygen content and mechanical properties: Gr1 has the lowest oxygen content (≤0.18%), offering the best toughness but the lowest strength; Gr2 has moderate oxygen content (≤0.25%), with strength over 20% higher than Gr1, good toughness, and the best cost-performance ratio; Gr3 has higher oxygen content (≤0.35%), the highest strength but slightly lower toughness, and is also more expensive. Gr2 titanium tubing is the optimal choice balancing strength, toughness, and cost, covering over 80% of industrial pure titanium applications.

2. Can Gr2 titanium tubes be welded? Will their performance degrade after welding?

Gr2 titanium tubes possess excellent weldability and can be welded using common methods such as TIG and MIG. No preheating is required during welding, nor is additional heat treatment needed afterward. The toughness of the weld zone can reach over 85% of the base material, and corrosion resistance is essentially consistent with the base material. There is no significant performance degradation, making them suitable for welding requirements in high-pressure and highly corrosive environments.

3. What is the approximate service life of Gr2 titanium tubes?

Service life depends on the application: in highly corrosive environments such as marine and chemical industries, it can reach 15–30 years; in general industrial applications, it can exceed 30 years; for medical implants, they can be implanted in the human body long-term without significant corrosion or performance degradation. A precise service life assessment can be provided based on specific operating conditions.
