Recently, i've got a task, it is mentioned that the model should be gas tight design in work order, i am confused about what's the mean of gas tight design and don't know how to start. could you please do me a favor to help me out? any examples? thanks in advance.
Gas tight means that gases (or air) must not be able to get in/out. Basically, a fully sealed design. Perhaps it has be sealed to a certain pressure? Do you have a spec of what pressure you must conform to or is "gas tight" all you've got to go on? What kind of part is it? If it's a seal, valve or pressure vessel, then I guess it being "gas tight" makes sense or it won't be much use!
