The sleeve core is made of stainless steel
SST-316 with internal ratchet locking mechanism. Outside gasket is
saturated with resin and mechanically pressed against the
host pipe when sleeve is expanded until it locks in place. The
resin is ambient temperature cured epoxy resin that seals the
sleeve in place and mechanically bonds to the host pipe, thus
sealing the joints and pin holes.

Benefits
of Link-Pipe Gas Sealer™ Sleeve System:
- Reduce capital costs
—Eliminate or postpone pipe replacements
—Strengthen pipe wall in areas weakened by corrosion
- Avoid traffic disruptions
& damage to customer property
- Increase safety
- Help meet allowable supply
disruption constraints set out in service contracts. (Up
to 46 joints have been repaired with the supply back in
service within 8 hours)
Technical
Data:
The Use of
Gas Sealer™ Sleeve:
- Cast Iron (low (0.25-0.5
psi) and medium (15 psi) pressures)
—Spot repair using expandable stainless steel sleeves
with sealant.
—Seals, joints, cracks, abandoned mains/services
—Applicable to pipes from 4" (100mm) to 54"
(1350mm)
- Steel (high pressure
up to 150 psi)
—Area repair with multiple sleeves of varying lengths
—Seals welds, flanged joints, and couplings
—Applicable to pipes from 4" (100mm) to 54"
(1350mm)
Gas Sealer™
Sleeves are available in diameters ranging from
4" (100mm) to 54" (1350mm) with standard lengths of 6"
(150mm), 8" (200mm),12" (300mm), 18" (450mm), 24" (600mm) and
36" (900mm)
Gas Sealer™
Sleeve in standard form is made
of Stainless
steel core covered with sealing material.
Sleeves
are equipped
with Ratchet Lock mechanism. The Ratchet Lock mechanism offers
dimensional compatibility to meet host pipe tolerances. Old cast iron mains may have unpredictable
variations in manufacturing tolerances, roundness and joint
offsets to which the sleeve must conform.
