T.D.Williamson - Z or U Seal and Concentric
U-SEAL™ and Z-SEAL™ Casing Seals
The U-SEAL™ Casing Seal
allows maximum flexibility for carrier pipe movement and
concentric installations. The Z-SEAL™ Casing Seal is a
thick, heavy-duty casing seal for installations where an
extra rugged seal is desired.
Insulators & Casing Cradles
Cradles are used to center the pipe in the end of the
casing, making it easy to install TDW Z-SEAL™ Casing Seal.
The cradles also carry the weight of backfill dirt and
insulate the pipe from the casing. They are recommended
for use with TDW Concentric Support Insulators.
Nonconcentric 3-Way Cradles restrain pipe in all
directions. They are used with U SEAL™ Casing Seals.
M-2 Plastic THINSULATOR®
The M-2 Plastic
THINSULATOR® pipe insulator is a high-density,
polyethylene product, injection molded to provide low cost
insulators of highest quality. This high-density
polyethylene gives the M-2 such strength that it is made
more compact than other insulators.
