DISPERSION
Steam loss of interconnecting vapor hose, tubing and pipe
Notes:
This data is based on an ambient air temperature of 27 °C, fiberglass insulation, copper tubing, and Schedule 40 pipe.
Maximum steam carrying capacity and length of
interconnecting vapor hose, tubing and pipe*
Notes:
* Based on total maximum pressure drop in hose, tubing or piping of 1250 Pa
** Maximum recommended length for vapor hose is 3 m. Longer distances may cause kinking or low spots.
*** To minimize loss of capacity and efficiency, insulate tubing and piping.
Developed length equals measured length plus 50% of measured length, to account for pipe fittings.
