Model HT (High Temp.) Non-Metalalic Casing Spacers

Description

A unique formulation of polymers is used in the manufacture of the Hi-Temp isolators/spacers giving them the ability to be used for applications that may reach 280-degrees F. (138°). In addition to heat resistance, they also offer excellent insulation, high abrasion resistance and low coefficient of friction for a wide variety of double containment carrier/casing pipe applications. Light in weight and easy to handle during installation, Model HT casing isolators also feature ribbed inner surface that prevents slippage and guards against carrier pipe coating damage. The outer surface may include any one of several molded runners to accommodate 2″ (50.8mm) x 4″ (101.6mm) or larger carrier/casing differentials.
One piece solid molded segments provide for maximum load bearing. Hardware includes cadmium plated steel studs, nuts and washers. A screwdriver is the only tool needed for installation.

Model HT Casing Isolators are designed primarily for smaller diameter steel or polyethylene carrier pipes (ANSI O.D. pipe without a bell or mechanical joint). We do not recommend that they be used on any carrier pipe over 12″ in diameter or for installations over 300 feet long without consulting with PSI. PE Isolators should not be used on concrete carrier pipe.

Recommended Maximum Spacing

Distance between all model HT Isolators/Spacers should not exceed 5-feet (1.5-meters) to 8-feet (2.4-meters) center-to-center. An isolator/Spacer should be placed within 2-feet (0.6-meters) on each side of a coupling or joint and within 1-foot (0.3-meters) of each end of the casing.
