<DIV><FONT size=3>The cost of pressure testing has as much to do with
multi-point measuring and analysis of distortion as it does with
just
seeing if the vessel can survive a given depth intact. There is a
depth
[above crush depth] at which the vessel undergoes enough stress
that one
cycle or repeated cycles can compromise the vessel even though it
might not
appear to have suffered. Vance and others can speak a lot more to
that
than I can.</FONT></DIV>

<DIV dir=ltr>Hi Hank,
<DIV><BR></DIV>
<DIV>I asked at Carderock over a decade ago and was told the
cost would
depend on setup time, which varies depending on how much
instrumentation
you want during the test, but that a typical figure was around
$27K.
Waaaay beyond my budget. Dale Heinzing tested Snoopy somewhere
on the
West side of Canada at a lumber yard. Snoopy went in the tank
alongside
the lumber and must have been pretty well disinfected, but the
scary bit
was that they released the pressure almost instantaneously,
with
a bang.
That test was to only 400' so not really sufficient for a
Nekton,
but it might still be of interest since I think it's relatively
close to
you and probably was inexpensive.</DIV>

in the

It

<DIV>
<DIV style="BACKGROUND: white"><SPAN><SPAN>ASTM A 516
or
ASME SA
516 grade is one of the most popular steel grades in
market .
</SPAN></SPAN><SPAN><BR><BR><SPAN>It is primarily
intended for
use in welded pressure vessels where notch toughness is
important. It comes in four grades 55, 60, 65 & 70.
At
Oakley Steel we mainly sell 516 gr 60 and 516 gr 70.
These
grades cover a range of tensile strengths from 55 - 90
MPa and
this versatility explains much of the specifications
popularity.
</SPAN><BR><BR><SPAN>For plates thinner than 40mm we
normally
supply them as rolled. Plates supplied above 40mm thick
are
normalised. </SPAN><BR><BR><SPAN>For A 516 grade 70,
which is
one of our most popular steels, the ASME standard
composition is
as follows (dependent on grade):
</SPAN><BR><BR><SPAN>Carbon
0.27 - 0.31% </SPAN><BR><SPAN>Manganese 0.79 - 1.3%
</SPAN><BR><SPAN>Phosphorous 0.035% max
</SPAN><BR><SPAN>Sulphur
0.035% max </SPAN><BR><SPAN>Silicon 0.13 - 0.45%
