ASME SB861 Titanium Seamless Tubes

ASME SB861 specifies requirements for titanium and titanium-alloy seamless tubes used in corrosive and high-temperature service. These tubes deliver excellent strength-to-weight ratio, outstanding corrosion resistance (including seawater and chlorinated media), and reliable performance for aerospace, industrial, and heat-exchange applications.

Why Choose ASME SB861 Titanium Tubes?

• High performance at low weight: Exceptional strength with ~40–60% weight saving over steel in many designs.

• Corrosion resistance: Outstanding in chloride, seawater, and oxidizing environments; ideal for condensers and desalination.

• Thermal stability: Well-suited for elevated temperatures in heat exchangers and process equipment.

• Cleanliness & biocompatibility: Favours critical services where contamination control matters.

Scope & Compliance (Standard Overview)

• Product form: Seamless titanium tubes and pipes.

• Typical delivery conditions: Annealed, cold-worked & stress-relieved, or hot-finished.

• Mandatory qualification: Chemical analysis, tensile tests, flattening/bend tests, and hydrostatic or NDE examination.

• Typical grades covered: CP Titanium (Grades 1, 2, 3) and alloys such as Grade 5 (Ti-6Al-4V), Grade 7, Grade 9, Grade 11, Grade 12, Grade 23, and others.

• Note: Size range, test panels, and supply specifics depend on purchase order requirements.

Popular Grades & Where They Fit

CP Titanium (Gr.1 / Gr.2 / Gr.3)

• Used in heat exchangers, condensers, and chemical processing where maximum corrosion resistance and formability are required.

• Strength vs. ductility: Grade 2 is the most common workhorse for industrial services.

Titanium Alloys (Gr.5 / Gr.9 / Gr.12 / Gr.23)

Typical Size Range (Custom on Request)

• Seamless OD: ~4–219 mm (0.16"–8.6")

• Wall thickness: ~0.5–20 mm (0.02"–0.79")

• Lengths: SRL / DRL & cut-to-length per project

• Ends: Plain (PE) or Bevelled (BE)

• Note: Final capability depends on grade, route, and MOQ. Share drawings to confirm manufacturability.

Mechanical & Quality Assurance Highlights

• Room-temperature tensile and yield strength per grade requirements.

• Flattening / bend tests to demonstrate ductility.

• Hydrostatic or NDE (UT / ECT / Radiography) testing for weld integrity where applicable.

• PMI & chemistry verification: N, C, H, Fe, O, and alloying elements controlled per order.

• Traceability ensured: Heat numbers and Mill Test Certificates (EN 10204 3.1 / 3.2) available on request.

Applications We Support

• Aerospace: Aircraft structural parts, hydraulic systems, brackets, and gaskets.

• Thermal systems: Heat exchangers, condensers, coolers in power and process industries.

• Process equipment: Reactors and piping used in chlorination, pickling, and FGD systems.

• Marine & desalination: Tubes for seawater and brine exposure.

• Medical / clean service: Where corrosion resistance and cleanliness are critical.

Ordering ASME SB861 Tubes (What to Specify)

Your RFQ Checklist

• Grade (e.g., Gr.2, Gr.5, Gr.9, Gr.12)

• Dimensions (OD × WT × Length) and tolerance class

• Delivery condition (Annealed / Cold-worked & SR / Hot-finished)

• NDE / hydrostatic preference, special acceptance criteria, or extra tests (e.g., IGC)

• End finish (PE/BE), surface finish (pickled, polished, BA)

• Required documentation (MTC 3.1 / 3.2, third-party inspection, export packing)

Advantages vs. Alternatives

• Compared to stainless steels: Lower density, higher specific strength, and superior chloride resistance.

• Compared to nickel alloys: Weight savings plus excellent seawater resistance — often lower lifecycle cost in marine environments.
