RX® Rubber expansion bellows

All installations may be subjected to movements. These movements can vary from very slow (thermal expansion or shrinking movements) to very fast (vibrations). Thermal expansion can result in adverse material stresses in piping. Fitting bellows can prevent these undesired material stresses.

Vibrations can also cause stresses, as well as unpleasant noise in the work and living environment. Fitting bellows can counteract this.

The solution for all these problems is the RX® bellows. The faultless functioning of bellows requires fitting to take place particularly carefully according to the instructions, and the pressure and temperature limits concerned may not be exceeded.

Our knowledge and supply capabilities in this field offer you the opportunity to choose the bellow to optimally meet your requirements.
