Single expansion joint solutions will induce pressure force and require main anchors

Benefits

Considerations

Highest system install cost from anchor size and number of alignment guides
Highest forces and risks, pressure thrust applies
Specialty expansion joints may be more costly
Main anchors required
Maximum number of alignment guides if anchors located away from expansion joint
Not typically used for hanging or rooftop systems
For lower system forces and install costs, consider a system with two expansion joints with a 90-degree elbow system
Main anchors, supports, and alignment guides are required for correct operation and safety

Tunnel, ground-based, riser, or buried energy distribution systems across large distances where anchors are practically located at ground level or to substantial structures
Commercial, Industrial, Power, Petrochemical, and Laboratory systems of all sizes and pressures

Two expansion joints with 90-degree elbow solutions do not induce pressure force and allow intermediate (non-pressure thrust) anchors

90-degree change in pipe direction required to allow lateral motion in each run
90-degree elbow to be supported but not restricted from motion
Two or more expansion joints are required to allow lateral motion in each run
Consider a single expansion joint solution if space does not allow a 90-degree direction change
Intermediate anchors, supports, and alignment guides are required for correct operation and safety

Any system location including hanging, pipe racks, pipe risers, rooftops, tunnel, ground-based, riser, or buried energy distribution systems
Force limited systems requiring small forces
Force limited equipment connections
Commercial, Industrial, Power Generation, Petrochemical, Marine, Defense, and Laboratory of all sizes and pressures
