3.2.3.3 Pipe Bending
(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
Fig.15, 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.
