Worked example of discharge pipe sizing
Figure on the left shows a G1/2 temperature relief valve with a discharge pipe (D2) having 4
No. elbows and length of 7m from the tundish to the point of discharge.
From Table:
Maximum resistance allowed for a straight length of 22mm copper discharge pipe (D2) from
a G1/2 temperature relief valve is 9.0m.
Subtract the resistance for 4 No. 22mm elbows at 0.8m each = 3.2m
Therefore the permitted length equates to: 5.8m
5.8m is less than the actual length of 7m therefore calculates the next largest size.
Maximum resistance allowed for a straight length of 28mm pipe (D2) from a G1/2 temperature
relief valves equates to 18m.
Subtract the resistance of 4 No. 28mm elbows at 1.0m each = 4.0m
Therefore the maximum permitted length equates to: 14m
As the actual length is 7m, a 28mm (D2) copper pipe will be satisfactory.
Essential recommendations for safety
The temperature/pressure relief valve should only be replaced by a competent
person.
No control or safety valves should be tampered with or used for any other
purpose.
The discharge pipe should not be blocked or used for any other purpose.
The tundish should not be located adjacent to any electrical components
