1) Q - Can Link-Seal® modular seals withstand
pressures greater than 20 psi?
A - Yes, where pressure exceeds 20 psi,
key factors to consider are: pipe surface, sleeve surface,
Link-Seal® modular seal compression, and proper installation
techniques. Contact CCP for more information.
2) Q - How much angular pipe movement will
Link-Seal® modular seals allow and still maintain a seal?
A - Link-Seal® modular seals may allow angular
pipe movement or misalignment depending on the ratio of annular
space of the penetration to the expanded range of the Link-Seal®
model sized for the penetration. Please call CCP for more
information.
3) Q - When is the recommended time to install Link-Seal®modular
seals?
A - Always install Link-Seal® modular
seals prior to any final connections. This helps prevent
off-center pipe alignment.
4) Q - Is it necessary to use WS or CS sleeves when
installing Link-Seal® modular seals?
A - WS model steel and CS model plastic
sleeves are specially designed for use with Link-Seal®modular
seals. When installed with Link-Seal® modular seals these
sleeves provide the best possible assurance of a quality wall
penetration system.
5) Q - What tools are required to install Link-Seal®
modular seals?
A - A socket or offset wrench with 5/16”,
1/2”, 3/8”, 9/16”, 3/4” & 1-3/16” sockets will handle all
installations. A low speed (450 RPM or less) power tool is
suggested for multiple installations to increase efficiency.
6) Q - Can I use power tools when installing
Link-Seal modular seals with 316 stainless steel bolts?
A - No, please refer to suggested installation
techniques.
7) Q - Sometimes when installing a Link-Seal®
modular seal belt, it hangs looseon the pipe even though all my
sizing calculations are correct. Why does it appear that I have too
many links?
A - Link-Seal® modular seals are
basically sized to fit the annular space, not the pipe. Use the
assemblies suggested by the charts or calculation. It may not
look right, but it will fit.
8) Q - Can Link-Seal® modular seals be used for
penetrations where the pipe is off-center to the opening?
A - Centering is very important. Contact
CCP for more information.
9) Q - How do I install Link-Seal®
A - Weld-beads and all other
irregularities on the pipe or opening should be addressed in
accordance with the manufacturer’s and/or project engineer’s
suggestions to provide a round, smooth and clean surface for
Link-Seal® installation.
10) Q - Is it necessary to use riser clamps, pipe
saddles and hanger supports with Link-Seal®modular seals?
A - Link-Seal® modular seals are
penetration type seals. It is not intended to be a structural
support. Standard pipe hanger practice should always be applied.
11) Q - My wall is 24” thick. Do I need Link-Seal®
modular seals on both sides of the wall?
A -- In many cases, one single Link-Seal®
modular seal assembly is appropriate. Double seals are typically
found in critical applications such as fire walls or nuclear
power stations. Double seals are also suggested for building
foundation wall penetrations where the wall thickness is greater
than 12”.
12) Q- Can Link-Seal modular seals be used with
manhole vault installed thimbles, not sleeves?
A - No, only if the area creates a
penetration cylinder, such that the axis of the cylinder is
parallel to the axis of the pipe going through it.
