Publication number: 20070089856Abstract: A tube support device for a tube bundle having a plurality of elongated tubes with a U-shaped bend portion is disclosed. The tube support device includes an elongated longitudinally extending strip having a pair of opposing faces. A plurality of tube engaging members extend from the pair of opposing faces. The tube support device includes an engagement assembly formed on one end of the tube support device. The engagement assembly is adapted to engage the anchor assembly positioned within the tube bundle, whereby the tube support device can be rotated into the desired orientation between the tubes to prevent vibration damage.Type: ApplicationFiled: October 6, 2006Publication date: April 26, 2007Applicant: ExxonMobil Research and Engineering CompanyInventors: Amar Wanni, Thomas Rudy

Publication number: 20060237179Abstract: A tube bundle device useful in heat exchangers, condensers and other devices which has a number of tube support cages placed at extended locations along the length of the tubes. After the initial construction of the bundle in which the tubes are inserted into the support cages the tube bundle is stiffened by inserting sets of tube stakes between the tube support cages, preferably at the midpoint of the tube span between the cages. The tubes are supported by rods or bars in each tube lane at the tube support cage locations and the rods in each cage are rotated axially with respect to the rods in the next adjacent cage; in a similar manner, the stakes in each set are rotated axially with respect to the stakes in the next axially adjacent set.Type: ApplicationFiled: June 26, 2006Publication date: October 26, 2006Applicant: ExxonMobil Research and Engineering Company Law DepartmentInventors: Amar Wanni, Thomas Rudy, Louis Curcio

Publication number: 20060162913Abstract: 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.Type: ApplicationFiled: October 12, 2004Publication date: July 27, 2006Inventors: Amar Wanni, Thomas Rudy, Marciano Calanog

Publication number: 20060108106Abstract: 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.Type: ApplicationFiled: October 20, 2005Publication date: May 25, 2006Applicant: ExxonMobil Research and Engineering CompanyInventors: Thomas Rudy, Amar Wanni, Marciano Calanog

Publication number: 20060070727Abstract: A tube support device for a plurality of elongated members is disclosed. The support device includes an elongated longitudinally extending strip having a pair of opposing faces. The strip includes a plurality of engaging members extending from the pair of opposing faces. The support device is sized such that the support device is located between adjacent rows of elongated members. The plurality of engaging members arranged such that a portion of the plurality of engaging members extend from one face of the opposing faces and are arranged to contact the elongated members positioned adjacent one face and another portion of the plurality of engaging members extend from another face of the opposing faces and are arranged to contact the elongated members positioned adjacent the other face. The plurality of engaging members are located adjacent one end of the strip and extend along only a portion of the length of the strip. The remaining portion of the strip contains no engaging members.Type: ApplicationFiled: October 20, 2005Publication date: April 6, 2006Applicant: ExxonMobil Research and Engineering CompanyInventors: Amar Wanni, Thomas Rudy

Publication number: 20050279487Abstract: 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.Type: ApplicationFiled: May 13, 2005Publication date: December 22, 2005Inventors: Amar Wanni, Marciano Calanog, Thomas Rudy, Malcolm Keen

Publication number: 20050006075Abstract: 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.Type: ApplicationFiled: May 19, 2004Publication date: January 13, 2005Inventors: Amar Wanni, Roberto Tomotaki, Thomas Rudy, Marciano Calanog
