How do I translate this sentence? Regarding the pressure envelope

As a safety measure, the oxygen level inside the system’s pressure enclosure should be reduced below its flammability limit before introducing the process hydrocarbons. Last edited by niuky on 2009-2-11 13:31.]

Pressure envelope – its meaning is easy to understand; it can be translated as terms like \"pressure chamber,\" etc. The appropriate term should be chosen depending on the context
As a safety measure, the oxygen content in the pressure vessel system should be reduced below the combustion limit before the process materials enter the system.
It should be reduced back --->>> WRONG As a safety measure, before hydrocarbons are introduced, the oxygen level should be lowered below the flammability limit within the system’s pressure range. (The ignition point is related to pressure)
For reference: As a safety measure, the oxygen level inside the system’s pressure enclosure should be reduced below the flammability limit before introducing the process hydrocarbons. As a safety measure, the oxygen content inside must be lowered below its ignition point before hydrocarbons are introduced into the system’s pressure-sealed area.

The term \"system envelope pressure shell reduce\" means to lower it, not to restore it; everyone should consider carefully what the appropriate term is for \"envelope\" as asked by the original poster: lol
The oxygen content within the system pressure enclosure should be reduced to......
“The \"pressure vessel\" seems to eliminate the cavity of the pressurized equipment. That “flammability limit” seems to refer to the flammability threshold (a concentration, similar to the explosion limit). The sentence means: Lower the oxygen content first before introducing hydrocarbons, otherwise there is a risk of fire. ）
Usually, people might think that pressure vessels do not include things like pumps and pipelines. That envelope is the enclosed space in which the materials might reside; it’s hard to find the right word for it.
Understanding of ‘System Pressure Envelope’: Personally, I believe that ‘Envelope’ does not refer to a container or cavity, but rather to the ‘system pressure range’. In other words, there is a dangerous range for oxygen levels with certain thresholds, while levels above the upper limit or below the lower limit are considered safe. A similar usage is ‘Phase Envelope’, which refers to the ‘phase boundary’.
\"Envelope\" has multiple meanings; using it to refer to an operation packet doesn’t make sense.
If it refers to the pressure chamber of a moving equipment unit within a system, it should be translated as pressure chamber; of course, it can also be translated as pressure vessel. If it is stationary equipment, then it should be translated as pressure vessel
Yes, it involves not only equipment but also pipelines. It’s best to come up with a universal term.
Thus, it can be translated as: As a safety measure, the oxygen content in the system should be reduced below the combustion limit before the process hydrocarbons enter the pressure phase system.
Why doesn’t it make sense? Simply put, it’s the partial pressure of oxygen within the system.
Find a source; there might be many of these in French. The envelope mentioned on the drawings provided by us in France refers to SHELL
Strong solidarity with Olivetree (I don’t know if he needs it?) ) The term “envelope” here probably refers to a \"boundary curve,\" as it reminds me of the maneuverability boundary curve of an airplane; I think it’s possible to draw an analogy. Plot the pressure-oxygen content curve in the x-y coordinate system; the area below the curve represents a safe zone.
Inside the........envelope – here, “envelope” refers to a physical structure such as a pressure shell, pressure enclosure, or pressure chamber. I’ve also seen the expression “welded to pressure envelope,” which confirms that it is a physical object rather than an abstract concept.
Everyone has a valid point; the question is, how exactly should \"envelope\" be translated here? I agree with OLIVETREE’s view
As a safety measure, the oxygen inside the system pressure envelope should be reduced below the flammability limit prior to the introduction of process hydrocarbons. As a safety measure, the oxygen in the pressure (protective layer) system should be lowered to below the lower limit for combustion of the hydrocarbons mentioned earlier.
