Standard pressure-vessel-code framing under ASME Section VIII — the default governing code for the large majority of tube sheet applications outside power boiler service.
| Application Scope | General pressure-boundary duty under ASME Section VIII |
| Division Options | Division 1 (standard rules) or Division 2 (design-by-analysis) |
| Structural Type | Any — Fixed, Floating, or U-Tube, per service requirements |
| Material | Any family, selected per fluid service |
The division you specify affects design margin and documentation burden, not the physical tube sheet itself.
Division 2 is typically used at higher pressure classes where its more detailed design-by-analysis approach can justify thinner sections than Division 1's simpler prescriptive rules — it comes with a higher engineering and documentation burden in exchange.
They overlap — most heat exchangers are also pressure vessels and are built to ASME Section VIII. This label emphasizes the pressure-boundary code compliance angle specifically, which matters for certain project documentation requirements.
Most do, since most tube sheets serve a pressure-retaining function, but the specific code requirement depends on your project's jurisdiction and end-use — confirm your exact certification needs with our engineering team.
Every enquiry is checked against governing code, material compatibility and manufacturing feasibility before a quote is issued. Use our product, material, grade and standards guides to freeze the RFQ — then confirm with engineering.
