CASING END SEALS
Advance Products & Systems End Seals outperform the costly and
labour intensive brick and mortar method of sealing casing ends.
While soil stress and pipe movement cause mortar to crack, the APS
products move with the pipe, insuring the integrity of the seal.
Unlike link-type sealing blocks that are limited to carrier/casing
differential and can only be used on a concentric profile, the APS
seals are totally flexible. APS offers four types of end seals which
can accommodate any combination of pipe sizes.
The model AC and AM are seamless and can easily be pulled on at the
time of construction while the model AW wrap-around is designed
to facilitate installation when the carrier line has already been
welded together and the pull is complete. Simply wrap around the
carrier and casing, remove the release liner from the two pressure
sensitive butyl mastic strips and press the adhesive strips down
to form a seal. Model AZ, zipper type end seal, wraps around the
casing end and carrier pipe and zips shut to provide a tight seal
while still allowing for pipe movement. All four are made of 1/8"
thick synthetic rubber assuring excellent chemical resistance and
resiliency and are secured with T-304 stainless steel banding straps
with a 100% non-magnetic worm gear mechanism to insure the integrity
of the clamp. Only a screwdriver is required for installation.
In addition, Innerlynx forms a mechanical seal between pipelines and
casing. Innerlynx forms a hydrostatic seal and electrically insulate the
carrier pipe from the casing. Innerlynx can be installed by one person
and requires no special tools.
