Condensate Drain Pipe Size

3 4 is sufficient for up to 20 tons according to the imc unless the drain outlet size is larger than 3 4.

Condensate drain pipe size.

When sizing condensate return lines in steam distribution system remember that the maximum condensate flow is achieved during plant start up when pipes and equipment are heated up. When it comes to having a condensate pipe installed there are certain restrictions in terms of size and position that must be considered. Works around acceptable flash steam velocities of 15 20 m s according to the pipe size and the proportion of flash steam formed. Where the drain pipes from more than one.

The minimum size for the overflow pipe is 21 5mm and needs to be made from a non metallic material for allowing a reasonable flow of water waste. Lines consisting of two phase flow such as trap discharge lines which are selected according to the pressures either side of the trap. Condensate waste and drain line size shall be not less than 3 4 inch 19 mm internal diameter and shall not decrease in size from the drain pan connection to the place of condensate disposal. The chart figure 14 3 5.
