Shell and tube heat exchanger symbol
Also called Heat exchanger, Exchanger
A shell and tube heat exchanger passes one fluid through a bundle of tubes and the other around them inside a shell, transferring heat through the tube walls.
What the shell and tube heat exchanger symbol means
A shell and tube heat exchanger passes one fluid through a bundle of tubes and the other around them inside a shell, transferring heat through the tube walls.
How it is drawn
A long horizontal shell with rounded ends and a U-shaped or straight line through it for the tubes, or, in the simpler ISO form, a circle with a zig-zag line passing through it.
Variants
- Circle with a zig-zag through it (general exchanger)
The shell and tube heat exchanger symbol in each standard
Drawn as on most US-style legend sheets.
Heat exchanger with straight tubes (fixed-tube plates). ISO draws the shell with the tube sheets and tubes inside. Floating head (2512) and U-tube (2513) types differ inside. The general heat exchanger, X8079, is a circle with a zig-zag line through it.
