ASTM B338 Grade 2 Titanium Tubing

ASTM B338 Grade 2 Titanium Tubing

ASTM B338 Grade 2 Titanium Tubing with certified quality and precisely controlled dimensions is LINHUI Titanium's specialty. Our seamless tubing, which has standard lengths up to 6000mm and outside diameters starting at 76mm, complies with ASTM B338 specifications.

To guarantee flawless delivery, every tube is put through 100% eddy current and ultrasonic testing. Our Grade 2 tubing provides outstanding corrosion resistance in industrial heat exchangers, desalination systems, and chemical processing equipment with oxygen level controlled below 0.25% and iron content within a maximum of 0.30%.

We keep more than 200 tons of ready-to-ship inventory. Our factory-direct supply guarantees complete EN 10204 3.1 material traceability while removing the need for middlemen. Custom orders typically have a lead time of 15 to 25 days, while expedited processing is offered upon request.

Key Features & Benefits

Increased Resistance to Corrosion

In oxygen-rich situations, the passive TiO₂ oxide layer self-heals. Because of this, Grade 2 tubing is resistant to chloride stress corrosion cracking in brine and marine applications.

Outstanding Formability

A minimum of 20% elongation permits expansion, bending, and flaring without cracking. The same workability throughout all heat lots will be appreciated by your fabrication crew.

Sturdy & Lightweight

Titanium tubing offers better strength-to-weight ratios for marine and aeronautical applications while weighing 40% less than stainless steel with a density of 4.51 g/cm³.

Manufacturing Process

Step 1: Preparing the Billet

To get rid of imperfections, high-purity titanium sponge is vacuum arc remelted (VAR). Strict grain structure control is applied during the forging and rolling of each ingot into billets.

Step 2: Cold Rolling and Extrusion

To achieve accurate wall thickness tolerance within ±0.05mm, seamless tubes are cold-rolled after being hot-extruded at regulated temperatures.

Step 3: Annealing

In furnaces with an inert environment, tubes are annealed at 650–750°C. This guarantees consistent mechanical qualities and removes residual stress.

Step 4: Concluding Exam

Surface flaws are found via 100% eddy current testing. Pressure ratings are confirmed via hydrostatic testing. Compliance with your drawings is guaranteed by dimensional examination.​​​​​​​

Quality Inspection

Non-Destructive Testing (NDT)

Eddy current scanning covers 100% tube length. Ultrasonic testing detects internal voids in thicker-wall variants. Defect detection sensitivity reaches 0.2mm.

Mechanical Property Testing

Flaring tests, flattening tests, and tensile testing validate formability and strength. Minimum yield strength of 275 MPa is verified per ASTM B338 requirements.

Chemical Analysis

ICP spectrometry confirms elemental composition. Combustion analysis measures hydrogen content to prevent embrittlement risks in service environments.

Documentation Package

EN 10204 3.1 mill test certificates include heat number traceability, mechanical test results, and chemical analysis data. Third-party inspection by SGS, TÜV, or DNV available upon request.

Applications Of ASTM B338 Grade 2 Titanium Tubing

Heat Exchangers & Condensers

Ideal for seawater-cooled systems in power plants and desalination facilities. Your maintenance costs drop dramatically compared to copper-nickel alternatives.

Chemical Processing Equipment

Resistant to chlorine, organic acids, and alkaline solutions. Tubing maintains integrity in pH ranges where stainless steel fails within months.

Marine Engineering

Offshore oil platforms and shipboard cooling systems benefit from zero corrosion in saltwater exposure. 30+ year service life documented in field installations.

Pharmaceutical & Food Processing

FDA-compliant Grade 2 material ensures contamination-free fluid transfer. Smooth pickled surfaces prevent bacterial adhesion in sanitary piping systems.

Export Markets

Over 60 nations on six continents are served by our ASTM B338 Grade 2 Titanium Tubing. North America (USA, Canada, Mexico), Europe (Germany, France, UK), the Middle East (UAE, Saudi Arabia), and Southeast Asia (Singapore, Malaysia) are the main export markets.

We continue to collaborate with EPC contractors such as CEFC, PTT, PETRONAS, and LUKOIL. For urgent projects, regional warehouses in Rotterdam and Houston allow for quicker delivery.

FAQ

Q: Is it possible to weld your ASTM B338 Grade 2 Titanium Tubing?

A: Indeed, Grade 2 provides exceptional weldability when employing ER Ti-2 filler wire and TIG or plasma arc welding. Silver-bright welds are preserved without embrittlement by argon shielding gas.

Q: What distinguishes welded tubing from seamless tubing?

A: For high-pressure applications, seamless tubes (ASTM B861) are chosen because they offer consistent strength without weld seams. Welded versions are less expensive and provide superior wall thickness consistency.

Q: Do you offer material traceability?

A: EN 10204 3.1 certificates with heat numbers connecting tubes to the original mill test data are included in every shipment. Documentation about the chain of custody is accessible for nuclear and aeronautical projects.

Q: Are you able to provide Grade 2 low-iron for corrosive environments?

A: Indeed, we make Low-Iron Grade 2 (Fe <0.05%) for hostile services like nitric acid, where a standard iron concentration could cause preferential corrosion.

Q: How much is the minimum order quantity?

A: The starting weight of stock items is 100 kg. A minimum of 500 kg is required by custom standards. Trial orders for the creation of new applications are supported by us.
