Technical Information: Tubes

Inside tube diameter

When the tube diameter is to small the flow velocity is increased which results in turbulence, increased temperatures and a pressure reduction. This then results in an increased energy demand for the entire system and increased conditions (temperature of the fluid, cavitation). This can result in premature wear and tear of the system.

A tube diameter that is to high increases the stress on the system and increases costs. We recommend to take the following flow velocities into account in hydraulic systems:

The following formula can be used in order to determine the inside diameter of the tube:
