Calgary Tunnelling carries a large inventory of pipe insulators for storm/sewer and utility carrier lines. Pipe insulators provide structural support and electrically insulate a carrier pipe from the casing line from which it must pass. Pipe insulators protect carrier lines from the casing and lend support to the carrier line as well as protect the line during installation.
Our heavy duty molded polyethylene pipe insulators have a high abrasion resistance and a low coefficient of friction, and are available for carrier pipe diameters ranging from 3/4 to 48 inches. We also cary custom sizable multi-line spacers, for special jobs that have more than one carrier line running through the casing pipe.
