2.6. Special Scenarios
2.6.1. Repairing joint offsets
Joint offsets of up to 3/8
” (1.0 cm) can be repaired with a single sleeve.
Repairing joint offsets with two sleeves
Never install a single sleeve centered directly over the joint.
1/3 of the sleeve should be positioned to one side of the joint, and 2/3 of the sleeve to the other side.
Joint offsets of 3/8
” to 1” (1 cm to 2.5 cm) must be milled out first. Only after can they be repaired
with a single sleeve.
Repairing joint offsets with two sleeves
If the joint cannot be milled, offsets between 3/8
” and 1” (1 cm and 2.5 cm) can be repaired using two
sleeves installed in a series.
The procedure for installing the sleeves is the same as the standard serial installation, except that
the sleeves are positioned slightly differently.
Where the two sleeves overlap, they form an angled joint that compensates for the offset and
ensures that the pair of circumferential seals are sufficiently compressed.
Installing the first QuickLock sleeve
Straight edged
With projecting rubber end
Placed approx.
12” or 16” (30 or 40 cm) into the offset joint, depending on the pipe diameter.
Installing the second QuickLock sleeve
Beveled end
Without projecting rubber end
Approx. 5/8
” (1.5 cm) metal overlap with the first sleeve.
Approx. 12 inches into the offset joint (6-
16” pipe diameters)
Approx. 16 inches into the offset joint (18-
32” pipe diameters)
