Pipe systems are everywhere. They help move water or gas from one area to another, which is very important to cities and towns everywhere. However, it can be challenging to navigate the various structures that pipes come in contact with when installing new pipe systems. Luckily, there are link seals to save the day when problems arise!
Link seals are very useful when it comes to sealing a pipe penetration. These mechanical systems help to seal annular space around pipes that pass through concrete walls, floors, ceilings, and other barriers. Annular space is the space between pipe and core hole that can cause major issues for system installation. Link seals are the best method for sealing annular space and are very easy to install. They are designed for special applications such as temperature extremes, chemical combinations, and slightly non-centered installations. Oil, gas, water, and air are no match for link seals!
Link seals are able to fit any pipe, but it’s important that the correct size be established for best results. But don’t worry; you can use our detailed Link Seal Chart to help! If your pipe type and size match with standard pipe charts then you will have no problem finding the perfect fit with this guide to link seal sizing.
Link Seal Chart Tips
We have many charts regarding link seal sizing and because of that there are some important things to remember when going over them. Keep these tips in mind when trying to size your pipes.
Link Seal Modular Seal Sizing
For Link Seal Modular Seal Sizing, you can find your pipe type and locate correct pipe size by using the Nominal Diameter and Actual Outside Diameter. Once you verify that your pipe O.D. matches the actual outside diameter shown on the chart, determine the type of wall opening to be used. Choose from Century-Line non-metallic (CS Model Sleeve), WS Steel Sleeve or Cast/Core Drilled Hole. Note that the sections outlined in gray represent Century-Line (CS Model Sleeve), WS Steel Sleeve, and Cast/Core Driller and from there you will be able to identify your sleeve model, the link seal modular size, and the number of links required for seal assembly.
Century-Line Non-Metallic Sleeve or WS Steel Sleeve Sizing
When ordering Link Seal modular seals, be sure to pay attention to the sleeve part numbers in columns CS Model Number (Century-Line) or WS Model Number. Always indicate sleeve length in inches. Century-Line sleeves are shipped standard in 16” lengths and can be field cut to as short as 8” in length.
Cell-Cast Hole Forming Disk Sizing
The CC Model Number represents Cell-Cast Disks. Be sure to combine 3” or 4” Cell-Cast Disks to create wall thickness. The threaded rod must be requested when ordered and you will need to specify TRA at the end of the ordering code.
Link Seal Sizing Method
Also in our Link Sizing Chart, you will be able to find that Pipeline Seal & Insulator, Inc. has re-evaluated the Link-Seal modular seal standard sizing for the sizing charts we have included. The updated method allows for the most rubber possible to fit into the hole. More rubber in the annular space produces a better performing seal which benefits the engineer, owner, and contractor. Because this may require a larger size link, we have included updated charts that will allow you to compare previous chart selections to the current ones.
