WebPage 54 of 105 o The lower velocity limit is desired to limit fouling, the higher velocity is limited to avoid erosion–corrosion on the tube-side, and Impingement attack and flow-induced vibration (FIV) on the shell side. o When sand, silt, and particulates are present, the velocity is kept high enough to prevent settling down. WebThis results in a split of the flow into either half of the shell with lower velocities and makes it possible to reduce the unsupported tube span length while keeping below a given allowable pressure drop. Tests were performed as a part of a systematic study of water flow-induced vibration in industrial-size heat exchangers.

WebJun 3, 2008 · Design guidelines were developed to prevent tube failures due to excessive flow-induced vibration in shell-and-tube heat exchangers. An overview of vibration analysis procedures and recommended design guidelines is presented in this paper. This paper pertains to liquid, gas and two-phase heat exchangers such as nuclear steam … WebPrevent flow-induced vibration in heat exchangers. New technology can be used in existing tube bundles to enable higher flowrates without risk of tube damage. Optimization of an existing process plant sometimes referred to as revamp or debottlenecking, can result in increased flowrates and higher velocities through the existing facilities ... grand hotel miramare portofino italy
