4. Bend pipe to the desired angle. Remove kinks or
ripples by pressing them flat then applying pressure to
the side of the flattened area. Work pipe until smooth
bend is complete. Use bend guide
(
BG-520
)
for more
precise control of angular and offset bends.
5. Hold the pipe in the bent position until the bend is set
and the pipe has cooled enough to handle without
gloves. Wipe pipe with a wet rag to set the bend and
cool the pipe.
Note: Remove kinks or ripples prior to cooling pipe.
After the pipe is cool the bent area cannot be heated
again and reformed.
Bending 2" through 4"
1. Wrap blanket around pipe. On large diameter pipe,
position blanket overlap on bottom of the pipe.
2. Support PVC on each end to lift off of the ground. Be
sure the blanket is not touching the supports. Any
object touching the blanket will produce a hot spot and
scorch the pipe.
3. Plug blanket cord in a receptacle. Check table “B” for
correct electrical source by blanket size. Allow 10 to 15
minutes for pipe to warm up. Check pipe flexibility by
pressing area within the blanket. When pipe feels very
soft, it is hot enough to form the bend.
Note: When bending pipe outdoors, cap or plug
both ends to prevent wind from entering and cooling
pipe while blanket is trying to heat. Use PVC pipe
plugs while heating and bending PVC sizes over 1
1
⁄2".
4. When pipe reaches maximum flexibility, remove and
unplug the blanket. Place pipe on wood sheet, not on
concrete floor. Begin forming the bend working from
the start of the bend and gradually completing the
entire angle. Large diameter PVC may be difficult to
handle and may require two people to make the
desired bend.
