- MSR Tubes
Specialization
In nuclear power stations,
Moisture Separator Reheaters (MSR)
dry and reheat steam exiting the
high pressure turbine before it
enters the medium and low
pressure stages. VALTIMET has
developed a proprietary method
of enhancing the outer tube
surface with integral fins, to
accelerate the heat transfer.
Our finned tubing promotes
economical material use and
reduces the MSR's size and cost.
Innovation
To meet the tolerance and
quality demands of nuclear
plants, VALTIMET has designed a
unique, totally integrated
production method for finning
stainless steel tubes, typically
in ferritic alloy 439L, under
the patented name of Valfin®.
Valfin tubes can also be
manufactured in austenitic
stainless steel or titanium.
These tubes are available with
19 or 27 fins per inch, in
lengths up to 46 meters, and are
bent according to customer
requirements. Their crest
diameter equals the diameter of
plain tubes so they can be
easily inserted through baffle
plates and plugged into tube
sheets.
Quality
You can count on our proven
reliability, in testing and in
use. VALTIMET's MSR production
lines are specially designed for
welding ferritic stainless
steels. MSR tubes undergo
ultrasonic testing, and are then
cold finned to yield optimum
quality. Finned tube samples are
taken at regular intervals and
examined on profile projectors
(called optical comparitors) to
assure dimensional conformance.
Afterwards, the entire tube is
heat treated, eddy current
inspected and bent to
specifications. Millions of
meters of Valfin tubes are in
service throughout the world
today.
