High Temperature Round Corner Rectangular Metallic Expansion Joints
Round Corner Rectangular Metallic Expansion Joints can be made with a 12"
inside radius round corner to eliminate stress risers that exist in the corners of mitered or camera corner rectangular expansion joints.
It is the best design for gas turbine applications because bellows will heat up at a uniform rate to minimize thermal shock.
The bellows will be close to the flue gas temperature at all times, providing that the bellows are
insulated externally. This will minimize condensate and sulfur based acids forming in the convolutions.
