Internal tube support for flow elements providing for tube expansion within the flow element shell

摘要

A tube mounting assembly for total traverse or static traverse sensing tubes is provided for use with Pitot tube devices where the tubes are allowed to expand and contract independent of the flow element shell. A female threaded pipe cap is tack welded or otherwise affixed to the inside internal surface of the flow element shell. A ½ inch NPTX tube fitting of the bore-thru fitting type is affixed to the pipe cap, and a traverse tube, sealed by high temperature packing or thread sealant between the tube and a tube nut, are then affixed to the opposite end of the bore-thru tube fitting.
