DN (Diameters upon request)
PRESSURE Project pressure according to customer specifications.
TEMPERATURE -200° ÷ 550°C. Possible variations depending on terminals.

For stainless steel: -200° ÷ 550°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.

Exhaust gas expansion joints


An exhaust gas expansion joint used to convey exhaust gases and absorb thermal expansion caused by high working temperatures. It consists of a single bellows inside which a flow conveyor is positioned to limit pressure losses due to the shape of the waves. It is typically used to convey exhaust gases in gas turbines, diesel engines and generators.



Exhaust gas systems. Gas turbines, ship engines, generators, diesel locomotives, special vehicle exhaust 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.
