a)
The welded seam of the second tube must face downward
b)
Ensure that the swage on the first tube is fully inserted into the second tube
c) Adjust the hanger so that it is located on the second tube, approximately 2" (5 cm) from
the end of the tube –
in this location the hanger supports both tubes.
d)
Slide the Torctite coupler into position across the center of the joint
e) Prior to tightening the coupler:
CHECK THAT THE SECOND TUBE IS LEVEL, ALIGNED HORI-
ZONTALLY AND VERTICALLY WITH THE FIRST TUBE –
MAKE ALIGNMENT ADJUSTMENT TO THE
TUBE CONNECTION AS REQUIRED
f) IMPORTANT: TOURQUE THE COUPLER BOLTS TO 40 ft
