Movement Capability
1. The degree of Angular movement is based on the maximum
extension shown.
2. If greater movements are designed, expansion joints can
be supplied with two, three or four arches in size of 100A
and larger. Can be supplied with two, three or four arches.
Relatively longer "Face-To-Face" length dimensions
are incorporated into the design of multiple Arch Type expansion
joints.
3. To calculate approximate movement of multiple Arch Type
expansion joints, take the movement shown in the above table
and multiply by the number of arches.
Spring Rate
1. Spring rates required to move expansion joints are based
on zero pressure conditions and room temperature in the pipe
line.
