Compensator Hoses

Metal hoses are used to compensate for a variety of movements encountered in the processing industry: vibration of equipment such as pumps; thermal expansions of piping, vessels and other equipment, equipment misalignment, and zero-load applications. These hoses should never be used to compensate for compressive axial expansion or movement of pipe. Compressive movement compensation is a job for specially designed expansion joints, which CSI also provides.


			Jacketed 8" x 10" compensator hose used in a vapor recovery system of polymer production. Hose compensates for lateral offset caused by thermal growth. Service temperature is 650 F (343 C).

	This jacketed modular unit for filtering viscous hydrocarbons utilizes compensator hoses to feed each of the eight filter housings. The flexible metal feed hoses compensate for the displacement of the filter housing lids when the filter cartridges need replacement.

			This jacketed flexible metal hose assembly is used to feed process into a batch reactor vessel mounted on load cells. Unlike rigid piping connections which create force vectors that affect the output of the load cells, flexible metal hose assemblies allow the vessel to be filled with chemicals to a prescribed volume (mass) without inducing stray moments into the measurement system.
