Can flared and jacketed hydraulic couplings be used as gas line couplings?
Yes, but it's not economical.Hydraulic pipe joint pressure is very high, commonly used in 16MPa, 25MPa, 35MPa several levels.
And it is not convenient to use, the general use of gas joints are fast plug.
The pressure of the pneumatic pipeline is usually 0.8MPa.Yes, the life is longer than the pneumatic one
