(TEMA) RCB-4.3

RCB-4.3 TRANSVERSE BAFFLE AND SUPPORT CLEARANCE

 

The transverse baffle and support plate clearance shall be such that the difference between the

shell design inside diameter and the outside diameter of the baffle shall not exceed that indicated in Table RCB-4.3. However, where such clearance has no significant effect on shell side heat

transfer coefficient or mean temperature difference, these maximum clearances may be increased

to twice the tabulated values. (See Paragraph RCB-4.43.)
