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-Sealmodular seals over a weld-bead?
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-Sealinstallation.
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.
