The Non-segmental is a Holtec patented tube support system used to promote axial flow in a tube bundle.

Non-Segmental Baffles

Holtec’s non-segmental baffle eliminates the problems associated with high volume shellside flows, since it provides total tube support while offering minimal obstruction to the passing fluid.

Furthermore, Non-Segmental baffles have been used by Holtec International in a variety of applications involving phase change (boiling or condensing), and thermosiphon flows.

In addition, the use of these baffles virtually eliminates flow-induced vibrations and premature tube failure.

Holtec’s non-segmental baffles are made from a flat metal strip that emulates the surface quality of typical heat exchanger tubing. Each strip is laser cut to ensure a precise lattice-like structure.

Typical materials of construction are 304 and 316 stainless steels; however other material can be used upon request. Tube hole clearances are within the TEMA and HEI limits.
