How to choose a sight glass for low-temperature pressure vessels
Thread Content
Our company is now preparing to manufacture low-temperature reactors capable of operating at -100° Celsius with a design pressure of 0.5 MPa. The customer wants these reactors to be equipped with sight glasses of DN100 size. However, the range of temperatures for which such sight glasses are suitable, as specified in standard NB/T47017, is determined based on the requirements for sight glass glass outlined in GB/T23259, which is 0–250°C. Is it feasible not to design the mirrors according to standards? Both the sight glass flange and the gland are made of stainless steel, and the strength calculations show they meet the requirements, so there should be no problems. The question is regarding the choice of material for the sight glass glass Ordinary tempered borosilicate glass may become unsafe at -10°; the solution suggested by the glass manufacturer is to use \"high-borosilicate glass\". Is it possible to use this material? Are there any relevant standard references?
How to handle adiabatic conditions? Just kidding?
It was the customer who requested additional viewfinders; frost formation wasn’t taken into consideration. Perhaps it can be checked after parking – it shouldn’t be necessary to check it while the device is in operation{:3_69:}
Both submersibles and spaceships have windows: lol
In this special industry, many things are particularly so. It’s only reliable to get familiar with a new and specialized industry before working in it
JB/T 6918-2017: Sintered metal and glass level gauges and sight glasses for refrigeration applications. This standard applies to level gauges and sight glasses used in refrigerators and other pressure vessels operating at temperatures ranging from -40°C to 180°C, with a design pressure not exceeding 8.0 MPa

-100°C still isn’t sufficient
