Ball joints are a conservative motion solution manufactured with thick components to provide increased safety. They provide pipe motion absorption via angular or torsional rotation without inducing pressure thrust force to the system.

Two or three ball joints are installed tandem in a leg of pipe, or a loop, perpendicular to the motion. Two ball joints are satisfactory for most applications—a third joint may be required for large movements or multi axis motions.

Ball joint loops often consume less than 25% of the area of a traditional pipe loop. Small to extreme motions are supported. Ball joint spacing lengths can be adjusted to reduce forces. Packed designs are used for higher pressures and temperatures.

Hyspan is the single source for expansion compensation, seismic connections, and vibration isolation.
