Subject: RE: Allow Sch 10 for 3.5" pipe

The 3.5" ,unfortunately is used in the most highly stressed regions on
the VV and we are using the Sch 40 for stiffness. The port 2 deflections
are high and it can not easily tolerate reduction in strength. Also, the
spacer sch 40 is used for handling. We need to do better than a simple
switch to thin material.

Importance: High

Paul,
Brad,
Mike called me and we discussed this a bit.  There is extremely short
supply
of Inconel pipe.  He has found quantities of sch 10 and 40 but not
sufficient
to cover the whole machine using only one type.  At first, he was going
to
propose doing one 120 degree segment one way and the others with the
alternate material.  I advised him that vessel symmetry was very
important so
he is suggesting choosing port 15 for the sch 40.  Please read the RFD
and
advise.  The pipe is on hold for a very limited time. Basically their is
one
supplier that has a limited supply of sch 40 and another that has a
limited
supply of the sch 10.

I will be absent from the lab next week. Please coordinate this amongst
yourselves.
Thanks,
Mike

Mike,

See if this can be answered quickly so I can buy this pipe, could be all
that's left in the world at this time.
