ASME SB338 UNS R50400 Seamless Titanium Tubes for Condensers and Heat Exchangers

Industry-recognized Grade 2 titanium tubing engineered for surface condensers, evaporators, and shell-and-tube heat exchangers where seawater, brine, or chloride-laden cooling media are specified.

Company Profile & Technical Authority

Yuhong Group Co., Ltd. specializes in the engineering and supply of heat exchangers, pressure vessels, and air-cooled equipment for power generation, chemical processing, and offshore applications. Our manufacturing scope encompasses complete tube bundles, U-bend tubes, finned tubes, and exchanger components including tubesheets, baffles, and channel heads.

Chemical Composition

Element	Weight % (max)	Element	Weight % (max)
Nitrogen (N)	0.03	Oxygen (O)	0.25
Carbon (C)	0.08	Hydrogen (H)	0.015
Iron (Fe)	0.30	Titanium (Ti)	Remainder

Complies with ASME SB338 Section II Part B requirements for Grade 2 (UNS R50400) material.

Manufacturing & Testing Requirements

Manufacturing Process: Cold-drawn seamless process performed in contamination-controlled environments. Titanium's high reactivity at elevated temperatures requires strict exclusion of carbon steel tooling contact, dedicated machining areas, and inert gas shielding during any thermal operations.

Mandatory Tests per ASME SB338:

Flattening test
Flaring (expansion) test
Hydrostatic or pneumatic pressure test
Eddy current or ultrasonic nondestructive examination

Quality Control Parameters: Outer diameter tolerance ±0.05mm; wall thickness tolerance ±0.03mm; H7-level tube hole tolerance for tubesheet fitment.

Complementary Fabrication Capabilities

Component	Material Grades Available	Fabrication Scope
Tubesheets	SB265 Gr.2 / SB265 Gr.12 / Clad Plate	Precision drilling to H7 tolerance; Ra ≤ 3.2 μm finish
Baffles / Supports	SB265 Gr.2	Laser-cut or waterjet; deburred and cleaned
Channel Heads	SB265 Gr.2 / Carbon Steel Lined	Code-stamped; design per ASME Section VIII Div.1
U-Bend Tubes	SB338 Gr.2	As-drawn or stress-relieved; in-line eddy current tested

Application Environments

Industry	Typical Equipment	Service Condition
Power Generation	Steam turbine condensers; cooling water heat exchangers	Seawater, brackish water, or treated cooling tower water
Offshore / Marine	Platform coolers; jacket water coolers	Chloride-laden seawater; MIC-prone environments
Chemical Processing	Shell-and-tube exchangers; evaporators	Corrosive process streams; elevated temperatures
Desalination	Brine heaters; distillate condensers	High-salinity brine; elevated chloride concentration
LNG / Refining	Lean/rich amine exchangers; overhead condensers	Sour service; sour water stripping

Technical Advantages

Corrosion immunity: Virtually immune to chloride stress corrosion cracking, pitting, and crevice corrosion across the pH range of seawater and brine environments.
Dropwise condensation: Low liquid wettability promotes dropwise condensation on tube surfaces, maintaining a continually renewed heat transfer surface.
Fouling resistance: Smooth surface finish reduces scale adhesion, extending cleaning intervals and sustaining heat transfer coefficients.
Material efficiency: Enhanced corrosion resistance permits thinner wall designs relative to copper alloys or stainless steels, improving thermal conductance.

Customization Scope: Tubes can be supplied in straight lengths or U-bend configurations; plain or low-fin surface profiles; beveled or plain ends; with full material test certificates (EN 10204 3.1/3.2).

Common Technical Inquiries

Q: What is the difference between Grade 2 and Grade 2H?

A: Grade 2H offers a guaranteed minimum ultimate tensile strength of 58 ksi (400 MPa) versus Grade 2's 50 ksi (345 MPa). Both share identical chemistry and may be certified under the standard specification.

Q: Can ASME SB338 Grade 2 tubes be used for ASME pressure vessel applications?

A: Yes. ASME Section VIII recognizes SB338 material. Grade 2H is explicitly intended for pressure vessel use.

Q: How does titanium compare with 90/10 Cu-Ni for seawater service?

A: Titanium provides practical immunity to seawater corrosion, eliminates velocity limitations, and withstands stagnant or low-flow conditions that accelerate copper alloy attack.
