29. Position black/red dual layer tubes; shrink in place.
Note:
Black/red dual layer tubes take longer to shrink than
previous tubes.
Center tubes over joint.
(1) Begin shrinking in center of tubes, working torch around
all sides of the tubes.
Pay particular attention to the back and
underside of the tubes.
(2) Before continuing, gently twist the unshrunk end of the
tubes to feel for resistance to movement in center indicating the
center is shrunk.
(3) Shrink from the center toward one end and stop about 5”
(125mm)
from the end of the tubes.
(4) Return to the center and shrink toward the other end, again
stopping about 5”
(125mm)
from the end of the tubes.
(5) Go back to first end and shrink the remaining 5”
(125mm)
of
tubes.
(6) Go back to second end and shrink the remaining 5”
(125mm)
of tubes.
(7) After completing these steps, heat the entire tubes for
approximately 1 minute.
Note:
(8) The raised ridges should disappear. Absence of
ridges can be observed by visual inspection and by feeling
surface with a gloved hand.
Post heat 1 minute
Inspect tube. Absence of raised ridges can be observed by
visual inspection and by feeling the surface with a gloved hand.
5"
(125mm)
Raised ridges will
recede during shrinking
Twist gently to check for
resistance to movement in center.
