INJECTION-MOLDED POLYETHYLENE SPACERS
Advance casing insulators are manufactured from injection molded high density virgin polyethylene. Benefits of polyethylene include high impact strength as well as abrasion resistance.
Once installed, the low friction of polyethylene facilitates easy installation into the casing. Molded into the inner surface are grooves which prevent slippage of any carrier pipe coating.
The Advance casing insulators have excellent dielectric resistance and low moisture absorption which yields minimal electric current loss and no impairment of cathodic protection. Sizes are available from 1″ through 60″ with a standard runner height of 1″. Casing insulators from 1″ through 12″ comprise two halves; two pi and four pi sections make up 14″ and above. Advance casing insulators are lightweight, economical and easy to install. Only a screwdriver is required for installation.
