Insulator Skids -Metallic Sewage

Description

Skids center utility pipes in casing pipe through which it must pass and are used in river crossings, canal crossings and bridge crossings as well as highway and railroad crossings. These are designed to ease of installation, are virtually corrosion proof and provide insulating protection from a possible electrical shorting between the carrier pipe and casing. No special tools are needed, no grease is used, and they are easily bolted on by a single worker. Metallic skids eliminate the need to fill the casing annulus with sand which is extremely labor intensive. Sand in the annulus also acts as an electrolyte thereby introducing unwanted current to the steel or ductile iron. Eliminating the annular fill allows for easy removal to repair or replace damaged sewage pipes.
