Condensate Drain Pipe Size Chart

Condensate drain piping to slope a minimum of 1 8 per every 12 horizontal attics or furred spaces.

Condensate drain pipe size chart.

Condensate waste and drain line size shall be not less than 3 4 in. When it comes to having a condensate pipe installed there are certain restrictions in terms of size and position that must be considered. Drain s 2015 imc 307 2 2 requires that an air conditioning condensate drain inside diameter should not be smaller than in ch and should not be smaller than the drain pan outlet diameter. Three quarters of an inch is sufficient for up to 20 tons according to the imc unless the drain outlet size is larger than in ch use t able 307 2 2 for condensate pipe sizing.

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. The chart figure 14 3 5. See more related questions demand is characterised as predictable high flow rates. Minimum condensate drain pipe sizing chart.

Internal diameter and shall not decrease in size from the drain pan connection to the place of condensate disposal. A rule of thumb the condensate load used to design condensate pipe lines should be twice the maximum production load. Drain lines containing no flash steam. Slope to be at least 1 8 per foot or 1 percent that is for every 12 horizontally there must be at least an 1 8 drop vertically.

Imc 307 2 2 tells us that an a c condensate drain inside diameter should not be smaller than 3 4 and should not be smaller than the drain pan outlet diameter.

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

Where the drainpipes from more than one unit are manifolded together for condensate drainage the pipe or tubing shall be sized in accordance with table 307 2 2.
