ASME SB338 Titanium Tubing

ASME SB338 covers seamless and welded titanium and titanium-alloy tubes for condensers, evaporators, and heat exchangers. If you’re seeking long service life in corrosive cooling media (seawater, chlorides, chemical process fluids), SB338 tubing delivers the strength-to-weight performance titanium is known for—while staying fully code-aligned for pressure equipment.

What Is ASME SB338? (ASTM B338 Equivalent)

• ASME SB338 is the ASME-adopted version of ASTM B338, commonly specified by EPCs and plant owners for code compliance. End users often write it as “ASME SB 338” or simply “B338.”

• Whichever form appears on your spec, we supply exactly to the required revision and project documentation.

• Looking for a trusted ASME SB 338 dealer? We stock, cut, test, and certify SB338 tubes with fast global dispatch.

Why Choose ASME SB338 Tubes

• Corrosion resistance in seawater & chlorides — ideal for surface condensers and desalination.

• High strength at low weight — easier handling and lower structural loads vs. copper alloys or stainless.

• Thermal reliability — stable in elevated temperature service for heat exchanger duty.

• Lower lifecycle cost — extended uptime and fewer unplanned shutdowns.

Grades Covered & Typical Uses

Commercially Pure (CP) Titanium: Grade 1, Grade 2, Grade 3

• Go-to choices for marine condensers, evaporators, brine coolers, and industrial cooling loops.

Palladium/Ruthenium-Stabilized & Alloyed Grades: 7, 11, 12, 16, 26, 28 (and others)

• Enhanced resistance in acidic/reducing or crevice-prone environments — great for chemical processing and pickling lines.

• We match grade to your fluid chemistry, temperature, velocity, and fouling risk.

Dimensional Range We Supply

• Seamless OD: ~6–114 mm (¼"–4½")

• Welded OD: ~12–114 mm (½"–4½")

• Wall: ~0.5–10 mm (SCH 10 to SCH 160 equivalents)

• Lengths: Single random, double random, or cut-to-length (U-bend on request)

• Ends: Plain (PE), Beveled (BE), or custom machined

• Tighter tolerances and special finishes — bright annealed, pickled, polished — available to drawing.

Manufacturing & Quality Controls (Per ASME SB338)

• Process: Seamless (cold-drawn/cold-reduced) and Welded (GTAW), with cold-work of welds to refine microstructure.

• Heat treatment: Annealed or stress-relieved per spec.

• NDE options: Eddy current, ultrasonic, radiography (for welds as required).

• Pressure tests: Hydrostatic or pneumatic on request.

• Mechanical tests: Tensile, flattening, flare, hardness; plus surface & dimensional checks.

• Documents: MTC EN 10204 3.1/3.2, heat traceability, third-party inspection (TPI) available.

Industries & Applications

• Power generation: Steam condensers, circulating water & cooling loops

• Desalination & marine: Brine heaters, MSF/MED plants, seawater coolers

• Chemical process: Acid production, pickling lines, chlorination systems

• Pharma & food: Corrosion-critical, cleanliness-focused heat exchange

• Oil & gas: Offshore platform cooling, utility exchangers

How to Specify ASME SB338 in Your RFQ

• Grade: (e.g., Gr.2, Gr.7, Gr.12; note any H-grade where applicable)

• Dimensions: OD × WT × Length (or tube count and TEMA layout)

• Condition: Annealed / cold-worked & SR

• Testing: NDE method, hydro/pneumatic, PMI if required

• Ends & finish: PE/BE; pickled, BA, polished

• Docs: MTC 3.1/3.2, welding procedures, TPI, country-of-origin
