Which type of flange with connection surface should be used for low-pressure pipelines transporting gas? RF? Which standard specifies it? Seeking advice, thank you!
It depends on the pressure; for pressures below PN40, RF is suitable, while for higher pressures, RTJ is necessary
Okay, thank you! The gas pressure is 30 kPa; in the past, FF models were always chosen.
FF is definitely not an option; GB50316 requires that flat flanges cannot be used for media with extremely high hazards. For pressures like yours, we use RF flanges
Okay, thanks for the advice! :handshake
