US 2014/0150915 A1 · OSCILLATING TUBE HAVING A SEGMENTED COATING FOR DAMPING THE TUBE

Abstract

The oscillating tube (10) includes a first end (12), an opposed second end (16), and a fluid conduit (18) defined by the tube extending between the opposed ends (12, 16). A segmented damping coating (20) covers in intimate contact a covered or coated portion (22) of the tube (10) so that the coated portion (22) of the tube includes at least about ten percent of an axial length of the tube and an uncoated portion (34, 36) that is not covered by the segmented damping coating (22) includes greater than about ten percent of an axial length of the tube (10). The segmented damping coating (20) may include polymers, polytetrafluoroethylene, single composition polymers, ceramic fibers, polymer fibers, reinforced polymer fibers including a polytetrafluoroethylene, ceramics, including monolithic and matrix ceramics, thermoplastics, carbon/graphic materials, silicon materials, metal rings or clamps, and combinations thereof.
