Classification of Motion Random Motion Such motion is non-predictable and occurs from the manual handling of a hose assembly. Care must be taken to prevent overbending of the hose and to avoid external abrasion of the wire braid. An armor covering of interlocked hose provides protection against these abuses. Axial Motion This type of motion occurs when there is extension or compression of the hose along its longitudinal axis. This class of motion is restricted to unbraided corrugated hose only and is limited to small movements and short lengths of hose. Angular Motion This type of motion occurs when one end of a hose assembly is deflected in a simple bend with the ends not remaining parallel.
Offset Motion Offset motion occurs when one end of the hose assembly is deflected in a plane perpendicular to the Longitudinal axis with the ends remaining parallel.
Traveling Loops In a piping system where axial movement must be accommodated or where the magnitude of the motion is in excess of the limits of an offset movement, the traveling loop configuration offers an ideal solution. In traveling loops, the centerline of a hose assembly is bent in a circular arc. Traveling loops accommodate movement in one of two ways. A constant radius traveling loop accommodates motion by varying the length of the arms of the assembly while the radius remains constant. A variable radius traveling loop accommodates motion by varying the bend radius of the hose assembly. Both types of traveling loops can be installed to absorb either horizontal or vertical movement. The constant radius traveling loop provides for greater movement while the variable radius traveling loop requires less installation space. Constant radius Traveling Loop
