Why Grade 2 Titanium Tube?
Grade 2 (UNS R50400) is the most widely used commercially pure titanium alloy, offering an optimal balance of strength, ductility, and corrosion resistance. Unlike stainless steel or copper-nickel alloys, gr2 titanium tube resists pitting and crevice corrosion in seawater up to 120°C. It also withstands wet chlorine, oxidizing acids, and organic media. For OEMs and EPC contractors, grade 2 titanium pipe reduces maintenance costs and extends equipment life by decades. TSM's CP titanium tubes maintain excellent formability – ideal for bending, flaring, and tube sheet expansion.
Superior Seawater Resistance
No pitting, no stress corrosion cracking in marine environments. Used extensively for desalination plants, offshore platforms.
Wide Temperature Range
Service from cryogenic -200°C up to 350°C (oxidizing conditions). Mechanical properties remain stable.
Excellent Workability
Easy to bend, roll, and weld. Suitable for U-tube heat exchangers and complex tube geometry.
Dimensional Specifications – Seamless & Welded Gr2 Titanium Tube
As a professional grade 2 titanium tube supplier, TSM offers both seamless (cold pilgered) and longitudinally welded (with full penetration) tubing. All dimensions comply with ASTM B338 and custom requirements.
| Type | OD Range (mm) | Wall Thickness (mm) | Length (mm) | Tolerance (OD/WT) |
|---|---|---|---|---|
| Seamless | 6.0 – 114.3 | 0.5 – 12.0 | up to 12,000 | ±0.05mm / ±10% |
| Welded & Drawn | 12.7 – 219.1 | 0.7 – 6.35 | up to 15,000 | ±0.10mm / ±8% |
| Heavy Wall Seamless | 25.4 – 219.1 | 8.0 – 25.0 | 3,000 – 8,000 | custom tolerance |
Standard tube finishes: pickled, polished, or bright annealed. We also supply grade 2 titanium pipe in schedule 5S, 10S, 40S. Custom lengths, plain or beveled ends available. Request your required dimensions for a quick quotation.
Chemical Composition – Grade 2 Ti
TSM uses high-purity titanium sponge to ensure strict control of interstitial elements, maximizing corrosion resistance and ductility.
| Element | N (max) | C (max) | H (max) | Fe (max) | O (max) | Ti |
|---|---|---|---|---|---|---|
| Grade 2 (R50400) | 0.03 | 0.08 | 0.015 | 0.30 | 0.25 | Balance |
Corrosion note: In seawater, Grade 2 exhibits a corrosion rate <0.001 mm/year. For environments with reducing acids or high temperatures >80°C, consider Grade 7 or Grade 12. TSM provides full alloy selection assistance.
Mechanical Properties
All gr2 titanium tube supplied in annealed condition provides consistent ductility for cold forming and expansion.
| Property | Minimum Value | Typical Value |
|---|---|---|
| Tensile Strength (MPa) | 345 | 380-480 |
| Yield Strength 0.2% (MPa) | 275 | 310-450 |
| Elongation (%) | 20 | 25-32 |
| Hardness (HRB/HB) | — | ≤ 150 HB |
Higher strength can be achieved via cold work, but annealed tubes are standard for corrosion service. Buy grade 2 titanium tube with full mechanical test certificates included.
Manufacturing Process – Made in China with Precision
Located in Shaanxi Titanium Valley, TSM operates integrated production: vacuum arc remelting (VAR) → billet conditioning → rotary forging → multi-pass pilgering for seamless tubes, or roll forming + TIG welding for welded tubes. Each lot undergoes solution annealing in a controlled atmosphere followed by pickling to remove alpha case. Our in-house lab performs PMI, tensile, flattening, flaring, and ultrasonic testing. As a certified grade 2 titanium tube manufacturer, we ensure 100% hydrostatic or eddy current inspection per ASTM B338.

Applications
Grade 2 titanium tubes are almost immune to chloride ions, and the oxide film formed on the surface is not only corrosion resistant but also inhibits the adhesion of sludge, making them stand out in many harsh environments.
Heat Exchange and Condensation
In condensers cooled by seawater or brine, titanium tubes do not exhibit pitting or ammonia corrosion like copper alloys. Although their thermal conductivity is not high, the tube walls can be as thin as 0.5 mm, and combined with higher seawater flow velocities, the overall heat transfer coefficient is actually better over long-term operation.
Seawater Desalination
In multi-stage flash evaporation and reverse osmosis systems, titanium tubes can withstand concentrated hot brine below 120°C without producing copper ions that would degrade membrane elements. Replacing RO concentrate pipelines with titanium tubes extends system life, and the pipelines can also withstand dilute acid cleaning.
Marine and Marine Applications
Titanium tubes can be used long-term in seawater pipeline environments without coatings or cathodic protection. They also have strong erosion resistance, allowing flow velocities much higher than copper-nickel tubes, enabling thinner wall thicknesses and reducing system weight by nearly 40%.
Chemical Equipment
In applications involving wet chlorine gas cooling, chlor-alkali reactors, and other contact with chlorine-containing oxidizing media, titanium heating coils are an effective and lightweight solution, provided fluoride ion levels are well controlled.
