No special tools are needed, no grease is used, and they are easily bolted on by a single worker. Silvertip Casing Spacers 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 pipes. With no need for this fill, Silvertip Casing Spacers are your answer to lower installation costs with continued access for maintenance.
Casing insulators are used to support and electrically insulate a pipeline from a 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. We recommend installation of polyethylene casing insulators every 6 to 8 feet.
With proven dependability and ease of installation, Silvertip Casing Spacers easily outperform the labor intensive, inefficient and unreliable wood skids. Just check the comparison below:
