TT-33 Peripheral bypass sealing in shell-and-tube heat exchangers
September 15, 2025
Component: Xist Date posted: 15 September 2025 In shell-and-tube heat exchangers, mechanical clearances between bundle components and between the baffle and shell are essential for bundle fabrication, insertion, and removal. These clearances are standardized in Section 5 of the TEMA Standards [1]. The resultant bundle-to-shell radial clearance (i.e., the gap between the...

TT-31 Beware of flow obstructions in inlet and outlet regions
February 14, 2023
Component: Xist, Xvib Date posted: 14 February 2023 Flow obstructions in the inlet and outlet regions can invalidate the Xist bundle entrance and exit velocities and thus impact the rho-V2 calculations. The Xist vibration analysis for shell and bundle entrance and exit areas is performed using the TEMA RGP-RCB-4.6.2 definitions. The...

S-SS-3-28 Optimal Application of Shellside Sealing Devices
January 16, 2017
This report documents two approaches to analyze the performance of different sealing devices. The first approach examines an exchanger with a fixed sealing device count and varied baffle spacing. The second approach considers an exchanger with fixed shellside geometry but different sealing device types and arrangements. Comparisons are made between experimental...
