Description

Short-Stop™ casing end electrical insulator is made of compression-resistant neoprene rubber and installed in casing ends. In addition to dielectric properties, Short-Stop is resistant to oil, water, ozone and chemicals. The Short-Stop insulator will also withstand a wide range of temperature variations.

Use

The Short-Stop end insulator is installed in casing ends between carrier pipe and casing to prevent metal-to metal shorts. Because of its unique slab form, it has no metal components that might cause future shorting-out.

Application Procedures

The casing end annulus should be cleared of foreign matter. Then the pipe is elevated, if necessary, off the casing inner wall. The Short-Stop insulator is placed in a cradling fashion into the bottom of the casing perpendicular to the longitudinal axis of the pipe. The insulator should extend out from the casing end approximately one inch. The pipe is then lowered down onto the Short-Stop insulator. Then an additional insulator segment is placed over the top of the carrier pipe.

Packaging

Short-Stop insulators are available in 1/2-inch and 1-inch thicknesses and cut to the length required. Standard width is 6-inches.
