Among the accessories in the self-acting pressure relief valve series are: PRESSURE PIPE, PRESSURE LINE, and PRESSURE TAP. I’m not sure how to translate these three terms; could anyone give some suggestions? Thank you
1# chrissyc: pressure guide tube, impulse tube, pressure tapping tube, pressure tap – for your reference.
IMPULSE means pulse, stimulus, or push. It seems a bit strange to use \"impulse tube\" as a translation for pressure guide tube
The accessories in the pressure relief valve only have Chinese names; what is needed is in C-E

I believe that the \"pressure guiding tube\" and the \"pressure sampling tube\" are the same thing, both of which can be translated as pressure tapping; if two different terms must be used, I suggest using \"pressure lead\" for the former (I have seen foreigners use this term). Another “pressure tap” – that’s right.
I really hadn’t paid much attention to it before; I just checked the project regulations and found two relevant sections – hoping they’ll be useful. Impulse line tubing should be as short as possible, with the number of joints kept to a minimum. All impulse lines must be installed at a slope of at least 10% downward for liquids or 10% upward for gases, leading toward the instruments. The length of the pressure transfer lines should be as short as possible, and the number of joints should also be minimized. All pressure tapping pipes should be installed with a slope of 10% downward (for liquids) or 10% upward (for gases) toward the instrument. The instrument air tubing shall be made of 316 stainless steel. It should be seamless and capable of being bent. The fittings used must be suitable for the type of tubing selected. Instrument air pipelines should utilize 316 stainless steel tubes. The pipeline should be seamless and easy to bend. The fitting should be suitable for the selected pipeline. All fittings, unions, etc. shall normally be with tapered threads (NPT) unless otherwise required. All joints, couplings, and the like should use tapered threads (NPT) unless there is a different requirement.
