A TUBE SHEET SEGMENT, A HEAT EXCHANGER, AND A METHOD OF MANUFACTURING A TUBE BUNDLE FOR A HEAT EXCHANGER

摘要

For supporting the tubes (1) in a tube heat exchanger there is provided a modular tube sheet segment adapted to fit around one tube and provided with support surfaces for engagement with similar support surfaces of adjacent segments. The outer dimensions and shape of the segment are adapted to precisely provide the desired axis spacing and the desired tube arrangement upon mutual engagement among uniformly shaped segments. Together the segments provide a sheet (12) which meets all the functional requirements of a tube support sheet. The invention further provides a heat exchanger comprising a tube bundle which is put together by arranging tubes with attached segments individually or in layers, and it provides a method of manufacturing a tube bundle which may form part of a heat exchanger.
