Heat Exchanger Tubes
Heat Exchanger Tubes
(OP)
Does anyone have a good source for finned heat exchanger tubes?
I have an application that requires straight tubes, 5/8" OD x 80" long with circumferential fins. The material is type 304 stainless steel and it must meet ASME Section VIII.
I am located in Washington State, USA (the other Washington!) so something close by would help, but I'd appreciate any good source.
Thanks
Tom W.

Thanks for the response. Energy Transfer is one I hadn't yet talked to. I think I did find a place that can do the job. The trick was that the customer needed fins that were 3/8" high and they would not accept copper or aluminum, and I had a hard time finding someone that could do these fins in stainless or mild steel. Cannon Boiler Works in PA can apparently do it, but I'll give Energy Transfer a call.
Thanks,

You may want to start a new tread on this topic.
In any case, it is not uncommon (at least within the refining industry) to have roll expanded stainless steel tubes in a heat exchanger. You should have no problem finding a heat exchanger fabricator with experience rolling stainless tubes. Try one of the TEMA contributing members, such as, Ohmstede, Cust-o-Fab or Energy Exchanger, if you'd like to get their opinion.
The decision to roll vs. weld also depends on the service fluid and operating conditions.

The latter is really slick (GM now makes some auto frames by hydrostatic shaping) and you can learn more about the Hydroswage process at www.haskel.com.
Each expanded joint can be tested for leak tightness right after the expansion. However, a main advantage of this process in the first place is the high predictability of the expansion effect once the pressure is set up.
