Typical Road Crossing
A Link-Seal® assembly installed at each end of pipeline casings at highway and railroad crossings provides positive, hydrostatic protection against the entry of water, soil and other backfill material and eliminates corrosion and ice damage in the annular space between carrier pipe and casing.
Unlike exposed pipeline boots, Link-Seal is positioned inside the casing, which protects it from being damaged by sharp aggregate, tools or backfilling equipment. Link-Seal's metal parts are completely encased either in solid rubber sealing elements or dielectric glass reinforced nylon pressure plates, preventing any metal contact which could cause a cathodic reaction.
Stating with some 10" diameter assemblies, we recommend Link-Seal with "centering blocks" in 25% of the links. These centering blocks, made of reinforced plastic, fit into molded openings in the Link-Seal. They are positioned in the lower 90° of each assembly.
Since the centering blocks are slightly thicker than the free-state (unexpanded) thickness of the rubber links, they position the pipe higher during initial stages of installation and prevent any pinching of the lower links or scraping of the pipe coating by the pressure plates.
