Gimbal Type Expansion Joints
Arsenflex Gimbal Type Seismic Expansion Joints are expansion joints with cranks used for absorbing axial, lateral and angular motions resulted from seismic motions (earthquakes) that occur in points with a risk of breaking.
Arsenflex Expansion Joints
When requested absorbing capability is higher than standard values, according to application they are used, they can be designed specifically for motion values calculated by project engineer.
Gimbal Type Seismic Expansion Joints are for protecting pipeline installation points and prevents them from damages resulted from seismic motions or subsidence.
