7.4 Stationary head 7 .4.1 Structural bracing shall not be used to retain pressure. 7.4.2 <strong>The</strong> pressure differential used to calculate the pass-partition plate thickness in accordance with TEMA (81h edition), RCB-9.132, shall be the allowable tube-side pressure drop of the entire exchanger unit. 7.5 Floating head 7 .5.1 Floating-head cover bolting shall comply with TEMA (8th edition), Section 5, Paragraph RCB-11. Bolt spacings and clearances shall be not less than the minimum recommended by TEMA. 7 .5.2 Floating-head cover bolting shall be readily accessible and shall have adequate spanner (wrench) clearance between the floating-head bolts and the shell flange at the cover end when the shell cover is removed. Charlie Chong/ Fion Zhang
7.5.3 Packed floating-head tailpipe and packed floating tubesheet designs (e.g. TEMA types P and W) shall not be used. P W P: Outside packed floating head W: External sealed floating tubesheet (Outside packed floating tubesheet?) 7 .5.4 Floating heads shall be designed for design pressure on either side, with atmospheric pressure or vacuum (if specified) on the other side, unless otherwise specified by the purchaser. Examples of acceptable floating-head designs are shown in Figure 1.
