2.6.3.7 Bending Pipes
(1) The pipes are shaped by your hands. Be careful not to collapse them.
(2) Do not bend the pipes in an angle more than 90°.
(3) When pipes are repeatedly bent or stretched, the material will harden, making it difficult to
bend or stretch them any more . Do not bend or stretch the pipes more than three times.
(4) When bending the pipe, do not bend it as is. The pipe will be collapsed. In this case, cut the
heat insulating pipe with a sharp cutter as shown in Figure 3-3-3, and bend it after exposing the pipe.
After bending the pipe as you want, be sure to put the heat insulating pipe back on the pipe, and
secure it with tape.
NOTE :

To prevent breaking of the pipe, avoid sharp bends. Bend the pipe with a radius of curvature of
150mm (5-7/8inch) or over.
②
If the pipe is bent repeatedly at the same place, it will break.
