Component Architecture & Specifications
| Core Assembly |
Governing Material Standard |
Primary Function & Engineering Rationale |
| Heat Exchanger Tubes |
ASME SA179 |
Seamless, smooth-bore tubes ensure minimal flow resistance and efficient heat conduction. |
| Primary Tubesheet |
ASME SA266 Grade 2 |
A forged or rolled carbon steel plate offering superior strength and dimensional stability for reliable tube anchoring. |
| Baffle System |
Typically SA516 Gr. 70 |
Configurable (segmental, NTIW) to maximize cross-flow velocity and heat transfer coefficient while supporting tubes. |
| Tie Rods, Spacers & Sealing Strips |
Carbon Steel |
Maintains precise assembly geometry and prevents fluid bypass around the bundle edges. |
| Header / End Closure |
SA105 or SA350 LF2 |
Forged steel component providing a secure and accessible interface for tube-side connections. |
