ASTM B338 Titanium Tubing

ASTM B338 is the standard specification for seamless and welded titanium and titanium alloy tubes used in surface condensers, evaporators, and heat exchangers. These tubes combine outstanding corrosion resistance with an excellent strength-to-weight ratio, making them ideal for power generation, chemical processing, and marine cooling systems.

Overview of ASTM B338 / ASME SB-338

• Covers 28 titanium and titanium alloy grades including Grade 1, Grade 2, Grade 3, Grade 5, Grade 7, Grade 9, Grade 11, Grade 12, and Grade 23.

• Available as seamless or welded tubes, with welded tubes cold-worked to refine the weld microstructure.

• Used extensively in industrial cooling, desalination plants, chemical reactors, and power plant condensers.

• Note: “ASME SB-338” is the ASME-approved version of ASTM B338 for code-compliant applications; “ASTM 338” is often used as shorthand in industry.

Key Features & Advantages

• Exceptional corrosion resistance: Performs in seawater, chlorides, and oxidizing environments.

• Lightweight & high strength: Up to 45% lighter than stainless steel with comparable mechanical performance.

• Thermal efficiency: Maintains strength at elevated temperatures in heat exchangers and condensers.

• Longevity & low maintenance: Reduces downtime and replacement frequency in demanding applications.

Grades & Applications

Tip: Always match grade selection with process fluid, temperature, and pressure conditions.

Dimensional Capabilities

• Seamless OD: ~6 mm to 114 mm (¼" to 4½")

• Welded OD: ~12 mm to 114 mm (½" to 4½")

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

• Lengths: Single random, double random, or cut-to-length

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

Manufacturing & Testing Standards

• Heat treatment: Annealed or stress-relieved.

• NDT options: Eddy current, ultrasonic, hydrostatic, or pneumatic testing.

• Mechanical testing: Tensile, flattening, flare, and hardness tests per ASTM B338 / ASME SB-338.

• Certification: Mill Test Certificates (MTC EN 10204 3.1/3.2) available on request.

Typical Applications

• Power generation: Steam condensers and seawater cooling systems.

• Chemical process equipment: Heat exchangers, evaporators, and reactors.

• Marine & desalination: Tubing designed for saltwater and brine exposure.

• Oil & gas: Offshore platform cooling and heat recovery lines.

• Aerospace & industrial systems: Lightweight, high-strength cooling lines.

How to Order ASTM B338 Tubes

When sending an inquiry or RFQ, specify:

• Grade (e.g., Gr.2, Gr.5, Gr.7, Gr.12)

• Dimensions (OD × Wall × Length)

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

• Testing preference (Hydrostatic, Eddy Current, UT, etc.)

• End finish and any special coatings/polish

• Documentation requirements (MTC, third-party inspection)
