Abstract
A tubesheet support arrangement 11 supports a tubesheet 10 within a vessel 12, the tubesheet 10 maintaining a plurality of tubes 22 at fixed radial spacings from one another with the tubes 22 extending from the tubesheet 10 on a tube projecting side of the radial plane RP. The tubesheet support arrangement 11 comprises a fully circumferentially extending intermediary support element 24. The intermediary support element 24 is subjected to compression due its support of the weight of the tubesheet 10 and the tubes 22 on the lower portion of the vessel 12.
