Feature of Angular Gimbal Expansion Joint
· Angular gimbal expansion joints can absorb any angular deflections by angular variation caused by thermal expansion or compression on the axis direction in ducts or containers.
· Anguar gimal expansion joints mainly used in complex ducts system to meet the angular deflection requirement, such as “L”, “Z” and “U” pipe system.
· Double angular gimbal expansion joints are designed applying in “Z” duct system to meet the angular deflection effected by thermal expansion. Prestretching of the expansion joints can provide much more compensate ability.
