Table 5 Schedule Of Equivalent Pipe Lengths - Hertz HDD Series Instruction Manual

TRANSPORTATION, HANDLING, INSTALLATION
➢ The valves, reducers, elbows, T-bar etc. used in the air installation result in pressure loss in the
products. Hence, your design of installation must take into account the pressure loss of each
connection element. In this context, you can see at the following table of equivalent pipe lengths how
many meters of pipe are approximately needed for each element.
TYPE
Stop Valve
Angled Elbow
Elbow
Large Elbow
T-bar
Reducer
Example : Using the same installation, for which the pipe length was found to be 328 ft in the first
formula, when you use 8 pieces of elbows of the same internal diameter of 1
pieces of stop valves, to keep the pressure loss at the same level, you can use
following formula:
(8x0.98) + (6x6.56) + (2x0,98) =49.82ft, and 328 – 49.82 = 278.18 foot maximum pipeline, using the above
components.
