Abstract

A method of manufacturing a tube sheet by forming a plurality of separate thin tube sheet segments; forming multiple holes in each sheet in a predetermined pattern, each hole for accommodating a tube sheet filter tube; aligning all of the plurality of tube sheet segments so that the hole pattern of each sheet aligns with the hole pattern in all other sheets of the plurality of tube sheet segments; and securing all of the tube sheet segments together to form a unitary tube sheet. A tube sheet construction that includes a plurality of separate thin tube sheet segments, multiple holes being provided in each sheet in a predetermined pattern, each hole for accommodating a tube sheet filter tube, all of the tube sheet segments being aligning so that the hole pattern of each sheet aligns, and fasteners for securing all of the tube sheet segments together. A media layer is provided between adjacent sheet segments.
