Twisted Tube S&T Bundles

Twisted Tube S&T Bundles

Twisted Tube S&T Bundles

(OP)
Someone in our refinery is looking at replacing a bundle with a twisted tube bundle.  does anyone have any experience with results, problems?

RE: Twisted Tube S&T Bundles

what is the purpose/justification of replacing the tube bundle? increase duty, corrosion, other(s), . . .

generally, taking an existing tube bundle and replacing it with an identical twisted tube bundle will increase heat transfer capabilities (overall U) of the exchanger, thus allowing for a greater duty.

a wise engr will take into the consideration all the process conditions and perhaps have the exchanger rated (thermally, mechanically, & hydraulically) by the mfg or heat xsfer specialist.

good luck!
