Product Detail
Product Introduction
Source Grade 2 titanium pipe and tube for heat exchangers, chemical processing and seawater service, with testing documents. Final supply is controlled by the grade, specification revision, dimensions, condition, tolerance, inspection and documentation stated on the approved order.
Why is Grade 2 common for process pipe and heat-exchanger tube?
Selection answer: Grade 2 offers a practical combination of CP titanium corrosion resistance, weldability and moderate strength for seawater, condenser, desalination and chemical equipment when the environment is suitable.
Selection boundary: Product standards serve different forms: ASTM B338, B861 and B862 should not be listed as interchangeable without defining tube versus seamless or welded pipe. Corrosion suitability also requires actual process conditions.
RFQ data to confirm: Provide the applicable product standard, seamless or welded route, OD or NPS, wall, length, ends, process medium, temperature, NDT and hydrostatic or pneumatic test requirements.
Product Specifications
| Product | Grade 2 Titanium Pipe & Tube | Grade | Grade 2 commercially pure titanium / UNS R50400 |
|---|---|---|---|
| Standard | Use ASTM B338/B338M for seamless or welded condenser, evaporator and heat-exchanger tube, ASTM B861 for seamless pipe, or ASTM B862 for welded pipe. Each includes Grade 2 / UNS R50400, but the product scopes and required manufacturing and testing routes are not interchangeable. | Size & Form | Seamless or welded tube and pipe; OD, wall and length are confirmed by RFQ |
| Tolerance | Applicable ASTM/ASME standard or customer drawing | Supply Condition | Annealed, pickled seamless or welded product with specified ends |
| Inspection | Verify the invoked standard and seamless or welded route, MTC, heat/lot identity, chemistry and tensile results, OD or NPS, wall, length, straightness, surface and ends. Define the applicable flattening, bend, electromagnetic, ultrasonic, weld examination and hydrostatic or pneumatic tests with required records. | Documents | MTC, heat/lot traceability and agreed inspection reports |

FAQ
What is the difference between ASTM B338, B861 and B862 for Grade 2 titanium?
ASTM B338 covers seamless and welded tube for condensers, evaporators and heat exchangers. ASTM B861 covers seamless pipe, while ASTM B862 covers welded pipe for general corrosion-resistant and elevated-temperature service. Select the standard from the actual product form and duty.
Is Grade 2 titanium pipe automatically suitable for seawater or chemical service?
No. Grade 2 is widely used in suitable oxidizing and chloride-bearing environments, but selection still depends on medium, concentration, aeration, contaminants, temperature, crevices, velocity, pressure and galvanic interfaces.
What information is needed to quote Grade 2 titanium pipe or tube?
Provide ASTM B338, B861 or B862 and revision, Grade 2 / UNS R50400, seamless or welded route, OD or NPS, wall or schedule, length, ends, quantity, service conditions, NDE, pressure testing, MTC and traceability.
