DN Diameters upon request
PRESSURE Project pressure according to customer specifications.
TEMPERATURE -200° ÷ 800°C Possible variations based on terminals

For stainless steel: -20° ÷ 550°C
For expansion joints with flanges in carbon steel: -20° ÷ 350°C
For a temperature range 50° ÷ 550°C performances (movements, working pressure, n° of cycles) must be reduced by applying the relevant coefficients (See document N205 Derating factors”).
For a temperature range higher than 550°C, please contact our Technical Department.



A universal expansion joint is one containing two bellows joined by a common central body. This type of compensator can absorb any combination of the three basic movements (axial, lateral and angular). The universalexpansion joint is indispensable when it is necessary to absorb large lateral movements that cannot be absorbed by a compensator formed by a single bellows. The latter is welded to two flanges.


Correction of static offsets and compensation for thermal expansion and movements. Superheated water, steam, diathermic oil, gas and inflammable fluid lines, gas and steam turbines, exhaust gas lines.


PED-certified in accordance with the mandatory regulation 2014/68/EU.

A type approval (TYPE APPROVAL) for marine applications can be applied if requested by the customer.
