Steam pipes heated from room temperature to operation temperatures - expands
Expansion of steam pipes when pressurized and heated from room temperature.
(inches per 100 ft Pipe)
Note! - to avoid unacceptable stress and damage in a steam pipe line - handle expansion properly.
Example - Expansion of Steam Pipe
- make 3D models with The Engineering ToolBox Sketchup Extension
A system is designed for pressure 120 psi with operating temperature 350 oF. As indicated in the table above (350 oF) the expansion is is approximately 2.4 in100ft pipe.
The expansion of a 90 ft long pipe can be calculated as
dl = ((2.4 in100ft) / (100 ft)) (90 ft)
= 2.2 in
