The connection structure of the gas pipeline is as follows: the gas pipe (2" inner wire) is connected to the inner wire flange (1 1/4") of the valve group through the diameter reducing wire (2" to 1 1/4").
The gas pipe connection structure is as follows: the gas pipe (2"inner wire) is connected to the neal flange (1 1/4") of the valve block by changing diameter to the wire (2"change 1 1/4").
The connection structure of the gas pipeline is as follows: the gas pipe (2 "inner thread) is connected with the inner wire flange (1 1 / 4") of the valve group through reducing the diameter of the thread (2 "to 1 1 / 4").<br>
