I’d like to ask about two abbreviations
Thread Content
Terms like VTC and CTC are often seen on engineering drawings; I’d like to know what they mean, and I’d also like to learn their full English names to make it easier to remember! Thank you first! :）
Has anyone compiled a list of abbreviations like these? Please share it so we can all learn from it! Sometimes it’s really impossible to figure out what these abbreviations mean. I’ve seen MTO many times before I finally understood what it meant; wow~~~~~~
It would be best to upload the image for easier analysis.
VTC likely stands for Variable timing control. As for CTC, there are explanations available on this forum; it is recommended to upload the diagram or relevant text, or indicate where it is marked on the diagram: http://bbs.hcbbs.com/thread-100764-1-1.html
VTC should be an abbreviation for Vender to confirm. Is CTC then Customer to confirm?
VTC stands for Vender to confirm {confirmed by the manufacturer}. CTC stands for Client to confirm; foreign technology companies or engineering firms do not make a strict distinction in their technical documents between BUYER, ENDUSER, and DESIGN INSTITUTE, referring to them collectively as CLIENT.{Confirmed by the buyer (design institute)}
Here we go again; usually, “PAD” is written next to ordinary wall-mounted angle valves. Could you tell me what PAD means and its full name?
A pad type flange, also known as a flange in common usage, is referred to as a threaded flange as well, because its connection threads are located in threaded holes rather than through-holes. These types of flanges are typically used to connect instruments, valves, etc.
VTC stands for Vender to confirm {confirmed by the manufacturer}. CTC stands for Client to confirm; foreign technology companies or engineering firms do not always make a strict distinction in their technical documents between BUYER, ENDUSER, and DESIGN INSTITUTE, referring to them collectively as CLIENT. {Confirmed by the buyer (design institute)}. This is a professional answer; generally, patent documentation includes annotations to that effect.
