How to optimise your compressed air piping system?


In order to optimise the performance of your compressed air piping system and to work in the best conditions, it is essential to follow the following 6 basic rules:

1- SET UP the main network in a "closed loop" configuration in order to limit pressure losses.
Indeed, the closed-loop configuration allows pressure losses to be reduced by half compared to an antenna configuration.

2- CHOOSE the diameter of the tubes judiciously according to the desired use. For this, refer to the table « choice of the pipe diameter ».

Choosing the right tube diameter for your application will save energy, which in the medium to long term can be very beneficial.

3-  CONNECT the compressor to the piping system via a flexible hose, to avoid vibrations.
Vibrations can have a negative effect on your air system, especially in the attachment of the tubes. For better safety, it is strongly recommended to connect the compressor with a suitable hose.

4- PROVIDE for the absorption of expansion or contraction of the system by using flexible hoses. As a result of temperature variations the air system can expand or contract. Therefore, it is imperative that the network is free at the ends to absorb these movements. We recommend the use of hoses in the corners. The following formula can be used to calculate the linear displacement of the tubes:

ΔL = ΔT x L x a

ΔL [mm] :linear expansion or contraction 

ΔT [°C] : temperature variation between the use temperature and the network installation temperature 

L [m] : total length of the network 

a = 0,024 [mm/(m°C)] : coefficient of thermal expansion of aluminium

5-  INCLINE the main network slightly (1% slope) to allow water to flow towards the drain point. SENGA's range of piping system includes water separating T-fittings to prevent water from entering the downpipes of your compressed air system.

6-  ARRANGE the fixing clips approximately every 2 m. Your installation must be securely fixed. The very light weight of SENGA pipes and fittings provides an additional guarantee of safety when fixing your piping system.
