For expansion joints with weld ends 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.
HINGED EXPANSION JOINTS WITH WELD ENDS
Excellent reliability, no ageing, absence of permeability, resistant to corrosion, high working temperature.
In conformity with EJMA (Expansion Joint Manufacturer Association) Standards, movements indicated in the technical tables are calculated for 3000 complete cycles at nominal pressure.
Correction of static offsets and compensation for thermal expansion and movements.
Superheated water lines, steam, diathermic oil, steam turbines.
