Abstract: A tube bundle device such as a heat exchanger or condenser which has parallel tubes in a triangular configuration in which tubes are adjacent and spaced from six surrounding tubes. The tubes in the tube bundle have wire spacer/support elements comprising helically wound material which surrounds at least a portion of the length of each of the tubes; each tube with a spacer/support coil being in contact only with tubes which do not have a spacer/support coil and each tube without a spacer/support coil is in contact only with tubes which have a spacer/support coil.

Abstract: A method of reducing vibration in a tube bundle includes inserting at least one elongated longitudinally extending support strip within at least one tube lane, wherein each elongated longitudinally extending support strip having a pair of opposing faces and a plurality of successive transverse tube support rows located at successive longitudinal locations along the strip, wherein each tube support row having a plurality of raised, tube-engaging zones, wherein the plurality of raised, tube-engaging zones extend laterally outwards to engage with tubes in the tube bundle on opposite sides of a tube lane, and orienting the at least one elongated longitudinally extending support strip such that each tube adjacent the tube lane contacts at least one of the transverse tube support rows.

Abstract: A support device for supporting a plurality of elongated members. The support device having a longitudinally extensive strip having a plurality of sets of transverse corrugations located at successive longitudinal locations along the strip. Each set of transverse corrugations forming a plurality of elongated member engaging zones extending laterally outwards from both faces of the strip to engage the elongated members in the tube bundle on opposite sides of a tube lane. The support device is useful to support elongated members in a bundle and to mitigate the possibility of damage from flow-induced vibration in elongated members.

Abstract: A tube support device is used with tube bundle devices such as heat exchangers or, condensers with in-line tube arrangements (rectangular tube configuration) to mitigate the possibility of tube damage from flow-induced vibration in the tube bundle. The tube support comprises an elongated member or strip which is intended to be inserted in a tube lane between the tubes of the tube bundle. Raised-tube-engaging zones which include transverse, arcuate tube-receiving saddles are disposed along the length of the strip at successive longitudinal locations corresponding to the tube positions in the bundle. These tube-engaging zones extend laterally out, away from the medial plane of the strip, so that the saddles receive and closely hold the tubes on opposite sides of the tube lane.

Abstract: A tube support device or tube stake which is useful to support the tubes in the bundle and to mitigate the possibility of tube damage from flow-induced vibration in tube bundles in heat exchangers, condensers or other tube bundle equipment. The tube stake comprises an elongated metal strip inserted in a tube lane between the tubes of the tube bundle. Raised-tube-engaging zones such as dimples or longitudinal corrugations are disposed in transverse rows across the strip at successive longitudinal locations along its length; these tube-engaging zones extend laterally outwards from both faces of the strip to engage with tubes on opposite sides of the tube lane. The tube-engaging zones are preferably arranged so that they extend from the two faces of the strip in an alternate manner, with the tube-engaging zones in each row alternately extending from one face and then from the other along the row.
