Steel Pipes - Temperature Expansion
The maximum and minimum length of a pipe depends to the maximum and minimum temperature of the pipe - in cold (non operating) and running (operating) condition. The temperature expansion coefficient steel pipes per degree change of temperature is nearly constant:
- 6.5 10-6 (in/in oF)
- 14.0 10-6 (m/m oC)
Carbon Steel Pipes - Temperature Expansion - Fahrenheit
The temperature expansion of carbon steel pipes expressed in inches per 100 feet per degree Fahrenheit:
Carbon Steel Pipes - Temperature Expansion - Celcius
The temperature expansion of carbon steel pipes expressed in mm per m per degree Celsius:
Example - Expansion of Steam Pipe
The expansion of 10 m steam pipe from an installation temperature of 20 oC to design temperature 180 oC (pressure 10 bar) is 2.4 mm/m or
10 (m) 2.4 (mm/m) = 24 mm
