Hello - we are installing a high-pressure helium recovery system here to recover
all helium from three Bruker 4K magnets. Although the preliminary plan was
to use 2" copper for the header (which will be ~75'), we are discovering that our
pathway will involve entering a drop ceiling and will require maneuvering around a
number of obstacles in the ceiling space. Consequently, using a flexible pipe
for the header is now looking quite attractive.
I know from this group that some of you have used CSST for your headers. Since
this tubing is not well known in our area, Id be curious to hear from those of
you who have used it. Ive reached out to a couple of suppliers locally and
it is obvious that the price/foot will be much more than copper for equivalent
diameters (50-125% depending on the brand). But other than price, being restricted
to buying full rolls of the CSST, and having to use fittings from the same product
line, are there any concerns from an installation and/or performance point of view?
My understanding is that the primary application for this tubing is transporting
natural gas and propane and so Im wondering about its performance when used for
helium service (in terms of creating leak-free joints).
Thanks,
Mike
