What you can read below
consist of a series of email communication, ending with pressure testing done for the welds / joints of the LN2 line around 1008.
I’ve include all the drawings that people have included in the conversations.

All,
Pressure testing of the welds and solder joints were completed this morning with no issue. Vaporizer line was depressurized at the end of the test.
Thank you,

Here is a quick layout of how it's isolated.
Line is isolated on the gas pad and in gas house. You can test whenever ready. The main n2 gas line that we use has a 350psi relief valve on it located on the south side of
the tank. So that line can go higher if needed. The new line parts that were installed near the tank has a 300psi relief.
Ill send around a few pict when i get back ro the office
Im off site today. I would like to confirm the outside valve at the mixing house us closed. It should be, but i havent looked at it in a while i can check tomorrow first thing
and let you know.
Rob,
I will make the pressure test to 150 PSI for that one solder joint and do a 10 minute hold per ASME. We will also do
a helium mass spectrometer test since we will have all the equipment out there anyway for the weld portion.
If the system can not hold pressure and my solder joint is good as determined by helium mass spectrometer, I will have
to defer to your team to make any repairs down stream of our alteration. The balance of that system is not part of our scope nor is it adequately documented for us to troubleshoot. This was the agreement when we first tapped into the system to provide the
80K hold to the magnet since Physics owns all that equipment.
I want to make this pressure and scope limitation clear before I apply any pressure to your system in case there are
components downstream that are not rated for 150PSI. If you are not comfortable with this please let me now so you can take more time to examine the system and the down stream components to ensure isolation or pressure ratings. I need to be clear on this
so we are not responsible for damage at the 150 PSI level or any down stream safety concerns once pressure is applied.
By this email and your previous replies, you are certifying that it is safe to pressurize the system to 150 PIS and
there are no down stream concerns.
We plan to start the test tomorrow morning. If you need more time to check items let me know. We can talk if that
is preferred.
Thank you,

We usually test to 50% operating pressure (100psi for us) when testing a new joint. 150psi would be a better test point.
In theory, that joint can see 200psi from the tank if someone shuts off the valve at the evaporator. We will not
operate there.
We will be isolating the tank and the reliefs for the test. I don’t think we should go to 450PSI for the vaporizer
lines.
Is 100 PSI adequate for you?
We are only test the first solder joint from our connection point, not the balance of this existing and presumed certified
system.
Thank you,

The tank's max is 216psi. There should be pressure reliefs on it, but I would have to go to the pad to see what they
are. We usually operate it at 90spi in the gas house so the Dry gas is probably 100psi or slightly higher at the evaporator.
Thanks. I'm getting out there too. If the label is right we have 450 psi max. I'm not sure the the line connected to it are rated for or if there are any pressure relief
valves on that's system.
Do you know the normal operating pressure of the vaporizer line?
If not, I'll just go with 100psi leak check to call the solder joint passing for ASME code.
Thank you,

Paul and Rob,
Yes, I walked over there. This is the tall vaporizer east of the LN2
dewar. I didn't know there were two of them.
