I have been designing and building these devices for over 20 years and have built over 50 such devices, but do so in a lab not subject to BPVC. This was not posted 'hoping' to to find somebody. I already know the device will work as designed, but the lab that the device is being built for...

I am designing and building a magnet for a research facility. The vessel that encases the superconducting magnetic coils has had a preliminary design done. The vessel will use 316N or 316LN because of the increase in strength at cryogenic temperature. The vessel is to be designed in the "spirit"...

Although you could do a leak test as such, It may not be an acceptable test to do. Helium is a smaller molecule and will therefore fit through a leak that a nitrogen molecule will not. That is why they are specifying helium as the leak standard instead of nitrogen. In mass spectrometer leak...

Section 3.2.1 of Div. II basically says this unless in 3.2.1.5 data are submitted and approved by the BPVC committee. This type of equipment may fall more into the category of outside the scope of this division under 1.2.4.2 C)pressure containers that are integral parts where the primary design...

I work in the field of superconducting magnet design. I am now designing a liquid helium vessel that carries 100 psi fluid pressure max. at -269 deg C. in addition to applied loads from magnetic coils creating as much as 800 psi mechanical loads on varying areas of the vessel. It is a flat plate...
