Checklist : Shell and Tube Heat Exchanger Layout

1

S&T Heat Exchangers perpendicular to Rack.

2

Floating head of heat exchanger 4* Meters away from Rack

3

Channel head of heat exchanger towards accessway

4

Tube bundle removal area of Tube bundle length plus 1* meter provided towards access way

5

Fixed saddle for Coolers with underground water pipe connections is towards accessway (Near Underground Cooling Water headers)

6

Fixed saddle of other exchangers as per Piping Flexiblility Requirements.

7

Piping not run over channel end or shell cover (Maintenance Req.)

8

Exchangers grouped wherever possible.

9

Maximum 4* S&T exhangers Stacked.

10

Maximum Centreline elevation of Stacked exchanger not more than 4200* mm from finished grade.

11

Reboiler located as close to tower as possible.

12

If plant access road used as tube bundle pulling area, alternate access available to isolated area.

13

Fire truck route not used as pulling area.

14

Minimum 450* mm clear provided between to adjacent S & T exchangers to remove bolting of channels and dished heads, if no operator access required between them.

15

Minimum clearance between two adjacent exchangers shall be 2 M* or 900* mm clear aisle if operator access required between them.

16

Reboiler elevatin as per PID.

17

Horizontal thermosyphon reboiler elevation is minimum.

18

Vertical reboiler supported from column is on Access road Side.

19

Reboiler piping checked for pressure drop.

20

Adequate space provided for bundle pulling of vertical reboiler.

21

Vertical reboiler accessible by crane.
