Condensate Drain Pipe Size

Drain lines containing no flash steam.

Condensate drain pipe size.

The condensate pipe sizing chart figure 14 3 5 can be used to size any type of condensate line including. The chart figure 14 3 5. 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. A rule of thumb the condensate load used to design condensate pipe lines should be twice the maximum production load.

Where the drain pipes from more than one. When it comes to having a condensate pipe installed there are certain restrictions in terms of size and position that must be considered. 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. 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.

Lines consisting of two phase flow such as trap discharge lines which are selected according to the pressures either side of the trap.
