Coated Steel

PSI polyvinyl chloride coated (PVC) steel casing isolators are often selected due to their strength and excellent corrosion resistance.

An extremely tough and durable heat fused plastic coating is offered on steel casing isolators 4" and larger, with 8" and 12" band widths. The cold formed steel casing isolator band, complete with runner studs installed, is vapor degreased, primed, heated and fusion coated with plastic, providing a minimum .010" (.254 mm) thick coating over the entire band and runner studs. A post cured cycle strengthens the bond and provides an even more uniform coating. Polyvinyl chloride is available as a standard. Other heat fused plastic coatings are also available for custom orders and applications.

The runners are attached with 3/8" diameter studs, which are fusion welded to the band before it is PVC coated. They are recessed far below the wearing surface of the runner. After the runner is anchored to the band, the stud counter-bore is filled to assure a water tight seal for the stud and the lock fastener.

Model Options

Model C8G-2: Coated Steel casing isolator with an 8" (203 mm) wide steel band and 2" (50.8 mm) wide glass reinforced runners.

Model C12G-2: Coated Steel casing isolator with a 12" (305 mm) wide steel band and 2" (50.8 mm) wide glass reinforced runners.

Stainless Steel

Tough, heavy duty 14 gauge (0.74" / 1.88 mm) 304 stainless steel isolators/spacers are available for use in highly corrosive environments. They offer maximum corrosion resistance while providing support for large diameter pipe, unusually heavy pipe or for long casing pulls. The flanges of the spacer are deep embossed and the corners are chamfered.

The runners are attached with 3/8" (9.5 mm) diameter studs, which are fusion welded to the band. The studs are recessed far below the wearing surface of the runner and, after the runner is anchored to the band, the stud counter-bore is filled to insure a water tight seal for the stud and the lock fastener.

Model Options

Model S8G-2: Stainless Steel casing isolator with an 8" (203 mm) wide steel band and 2" (50.8 mm) wide glass reinforced runners.

Model S12G-2: Stainless Steel casing isolator with a 12" (305 mm) wide steel band and 2" (50.8 mm) wide glass reinforced runners.

Typical spacing for all PSI metallic casing isolators / spacers

A8 / C8 / S8 = 7 (2.1 m) to 10 (3.0 m)

A12 / C12 / S12 = 8 (2.4 m) to 12 (3.7 m)

An isolator/spacer should be placed within 2 (0.6 m) on each side of a coupling or joint and within 1 (0.3 m) of each end of the casing.

Ranger Il®, All Non-metallic

An all non-metallic spacer system designed to ease carrier pipe insertion, reduce inventory costs, make installation quick and easy to last for the life of the piping system.

Features:

All non-metallic. No nuts, bolts, washers or any other metal parts to corrode or degrade over time.

Segmented pieces - small inventory may be used to accommodate a large variety of pipe styles, types and diameters. No extra trips from job site to warehouse for additional parts.

Easy assembly. Simply slide the segments together and ratchet tight with the patented Slide-Lock connecting system.

Wide variety of runner heights to allow numerous options for pipe positioning within the casing.

Manufactured from UV resistant polypropylene.

No special tools required for installation.

Accommodates plastic, ductile iron and steel carrier pipe (not suitable for concrete pipe).

Model Options:
For carrier pipe diameters from 0.83" (21 mm) to 37.60" (955 mm) in diameter. See our Ranger II web page for runner heights, configuration options, ordering information and installation instructions.

Band/Runner Segment Specifications

Material, UV resistant polypropylene.

Compressive Strength, 3,000 lbs/sq.in (211 kg/sq.m)

Temperature, -40ºF to +180ºF (-40ºC to +82ºC)

Impact Strength, 1.5 ft.lb/sq.in (10.34 kPa)

Dielectric Strength, 800 Volts/mil min.

Color, Black

Liner, None

Typical Installation
Based on 20 (6.1 m) carrier pipe segments in a casing of not more than 300 (91.5 m). Consult CCP for longer casings and for concrete pipe.

Typical Specification

Casing spacers shall be all non-metallic (polypropylene), molded in segments for field assembly without any special tools. Spacer segments shall be secured around carrier pipe by insertion of a cinching spline. The casing spacer polymer shall contain ultraviolet inhibitors and shall have a minimum compressive strength of 3,000 psi, an 800 Volts/mil dielectric strength and impact strength of 1.5 ft-Ibs/inch. Each casing spacer shall have full length, integrally molded skids extending beyond the bell or mechanical joint of the carrier pipe.

Each casing spacer shall be manufactured at a facility that has a Registered ISO 9001:2000 Quality Management System. Copy of current ISO 9001:2000 Registration shall be provided with material submittal.

Approved vendor: Corrosion Control Products Company.

Recommended Maximum Spacing

All Ranger II® Isolators/Spacers should not exceed 8 (2.4 m) center to center.
An isolator/spacer should be placed within 2 (0.6 m) on each side of a coupling or joint and within 1 (0.3 m) of each end of the casing. For more details on spacing, contact CCP.
