- No change in direction required
- Lowest pressure drop if no changes in direction
Expansion joints in Multi Axis pipe systems move in at least two planes. The motions may be parallel and perpendicular to a pipe centerline, or in two perpendicular plane. Solutions include a single expansion joint for all motions or two expansion joints with a 90-degree elbow.
Single expansion joint solutions will induce pressure force and require main anchors
Two expansion joints with a 90-degree elbow solutions do not induce pressure force and require only intermediate (non-pressure thrust) anchors.
