Regarding gas flow measurement and shut-off
Thread Content
Experts, I have some questions I’d like to ask; I hope you can offer your guidance! How is gas flow meter selection generally carried out, and what considerations apply when the pipe diameter is large? How should one choose a quick-release valve for gas? Anyone with experience, please share your insights. Thanks in advance
Also, which brands are good in this area? It would be great to have their contact information
We use Anuba for gas supply; we also have emergency shut-off valves, which are actually two disc valves, with a vent in between
Is it because the diaphragm valve doesn’t have very good airtightness that two seals are used?
For measuring coke oven and blast furnace gas, orifice plates or Tobia tubes are generally used; for shutting off the gas, quick-acting shut-off valves will suffice, and they are available in both electric and pneumatic versions
That’s indeed the case; leak detection often fails because the pipe diameter is too large, at DN1000, and other types of valves are also not suitable
