Installation Process
Installing Link-Seal modular seals requires some tools, preparation, and a step-by-step process․ Proper preparation is crucial for a successful and lasting seal, ensuring it is secure and effective․
Required Tools and Preparation
To properly install Link-Seal modular seals, gather necessary tools such as a cleaning material, measuring tool, torque wrench, and a marking aid․ Ensure the pipe is centered within the opening․ Proper preparation involves cleaning the pipe and the inner surface of the penetration․ Also, double-check the annular space between the pipe and the penetration to choose the correct size․ Having the right tools and careful preparation will ensure a smooth and effective installation of the seal and its long-lasting performance․ This step is critical for achieving a secure seal․
Step-by-Step Installation Guide
Begin by centering the pipe within the penetration․ Next, install the Link-Seal belt, ensuring the pressure plates are evenly spaced around the circumference․ Then, using the sizing charts, install the exact number of links required for the given annular space․ Tighten the bolts with a torque wrench to the specified value․ This process ensures a secure and watertight seal․ Following these steps will result in a professional and effective installation․ Always use the correct amount of links as indicated in the chart for optimal sealing performance․
Sizing and Selection
Selecting the correct Link-Seal involves determining the annular space between the casing and carrier pipes․ The ideal seal is smaller when relaxed and larger when tensioned, using sizing charts․
Determining the Correct Link-Seal Size
The correct Link-Seal size is crucial for effective sealing․ This determination hinges on the thickness of the annular space between the casing pipe or wall sleeve and the carrier pipe․ The perfect Link-Seal, in its relaxed state, will be smaller than this annular space․ Conversely, when tensioned during installation, it should expand to be larger than the space․ Proper sizing ensures a tight and reliable seal against water, soil, and backfill material․ Accurate measurements are essential for a correct fit and optimal performance, and sizing charts will guide this process․
Using Sizing Charts for Optimal Fit
Sizing charts are indispensable tools for selecting the correct Link-Seal․ These charts provide precise dimensional data, including the actual outer diameter and the corresponding pipe size․ When using the charts, it’s important to note the inner diameter of the hole where the seal will be installed․ The charts allow you to determine the exact number of links needed for a secure fit․ Remember that after calculation based on chord length, the results must be rounded down to the next whole number of links․ Using these charts ensures that the Link-Seal fits properly, maximizing its sealing capability․
