Product Detail
Product Introduction
A titanium tube sheet is a thick machined exchanger component that positions tubes and transfers loads into the shell or channel. Material route, clad or solid construction, hole geometry, ligaments, gasket faces and tube-to-tubesheet joint details must follow the approved equipment drawing.
Selection Priorities
Material route
Define solid titanium, titanium-clad construction or other approved design, grade, raw-material specification and heat-treatment condition.
Hole pattern
Provide tube-hole diameter and tolerance, pitch, layout, groove geometry, ligament, drilling depth and burr requirements.
Equipment interfaces
State overall diameter and thickness, bolting, gasket faces, grooves, steps, tube projection and joint procedure.
Product Specifications
| Product | Titanium Tube Sheet | Grade | Titanium Grade 2, Grade 7, Grade 12 or specified alloy |
|---|---|---|---|
| Standard | ASTM B265 / ASME SB265 plate or ASTM B381 / ASME SB381 forgings are the primary material references when applicable. RFQs using EN/W.-Nr. 3.7035, JIS Class 2 / TP340 or GB/T TA2 terminology can also be reviewed, but these are not automatic substitutes: state the exact product-form standard and revision. The finished tube sheet is controlled by the ASME/TEMA or project drawing, machining tolerances and approved inspection plan. | Size & Form | Round, segmented or drawing-specific tube sheet by diameter, thickness, hole pattern and machined features |
| Tolerance | Approved drawing tolerances for diameter, thickness, flatness, holes, pitch, ligaments, grooves and faces | Supply Condition | Rough or finish machined, solid or approved clad construction, protected faces and holes in export cases |
| Inspection | Diameter and thickness, hole mapping and gauging, pitch and ligament checks, face flatness and finish, groove dimensions, visual inspection and specified NDE are reviewed against the drawing. Product test certificates can be provided. | Documents | Product test certificates can be provided. |

Product Packaging
Sheet and plate surfaces are interleaved or wrapped as required, protected at edges and secured on pallets or in export cases with grade, heat and dimensional identification. Typical export packaging for the same physical product form is shown below; final packing is confirmed for each order.
Application Scenarios
Shell-and-tube heat exchangers
Material grade, dimensions, condition and inspection must be matched to the application requirements.
Condensers and evaporators
Material grade, dimensions, condition and inspection must be matched to the application requirements.
Chemical, desalination and marine equipment
Material grade, dimensions, condition and inspection must be matched to the application requirements.
FAQ
Is a titanium tube sheet simply a perforated plate?
No. It is a designed pressure-equipment component with controlled raw material, thickness, hole pattern, ligaments, faces, joints, tolerances and inspection.
Can a tube sheet be made from plate or forging?
The permitted raw-material route depends on section size, equipment design, code and approved specification. State the required route in the RFQ.
What drawing data is essential?
Provide overall geometry, hole layout and tolerance, grooves, gasket and bolting faces, tube projection, material route, NDE and documentation.
