Flare Processing
1. Cut the pipe using the pipe cutter.
❏
Pipe Bending
1. Perform bending of the pipe using the bender which has a specified bending
radius.
2. Be sure to take full care to perform bending of the pipe successfully at one
time. Bending and unbending the pipe more than twice makes the bending
work increasingly difficult.
3. You may use the spring inserted into the gas pipe instead of the bender to
bend the pipe.
4. When you bend the pipe using the spring, hold the pipe with both hands to
prevent any distortion, and secure a minimum bending radius of more than
100mm(4").
❏
Tightening of Connection Parts
◆ Align the center of the connection piping, and tighten the flare nut
by turning it with hand. Then tighten it again using the spanner in
the direction as shown in the figure.
2. Insert the flare nut into the pipe, and then perform the flare processing.
