Casing Spacers

APS offers a proven solution with Casing Spacers to outperform the labor intensive, unreliable use of wooden skids. Casing Spacers center water and sewer pipes in casings with easy installation, are virtually corrosion proof, and provide insulating protection from a possible electrical shorting between the carrier pipe and casing pipe. No special tools or grease needed, and they are easily bolted on by a single worker. APS Casing Spacers eliminate the need to fill the casing annulus with sand which is extremely labor intensive. Sand in the annulus also acts as an electrolyte thereby introducing unwanted current to the steel or ductile iron. Eliminating the annular fill allows for easy removal to repair or replace damaged pipes. With no need for this fill, APS Casing Spacers are your answer to lower installation costs with continued access for maintenance.
Casing Spacers Model
Casing insulators are used to support and electrically isolate a pipeline from a casing pipe through which it must pass and are used in river crossings, canal crossings and bridge crossings as well as highway and railroad crossings. We recommend installation of casing spacers every 6 to 8 feet.

Benefits:

♦Isolation of the carrier pipe from the casing pipe achieved with non-conductive runner or roller options
♦Protects against damages of the carrier and the casing pipe during the installation process
♦Gives the carrier pipe the desired height within the casing pipe
♦Easy and efficient installation with no grease or special tools required
♦No backfill required
♦Long-term corrosion protection

Model SI (Carbon Steel) & Model SSI (Stainless) Spacers

Heavy duty two-piece stainless steel or carbon steel bands by APS serve virtually every piping application and should be utilized inside casing that is 2 or 3 pipe sizes larger than the carrier pipe. APS steel band casing is available in two widths: 8″ width is recommended for carrier pipes 4″ to 24″; 12″ width for carrier pipes 26″ to 120″ and larger. The band is constructed of 14 gauge steel with a 90 mil EPDM liner. Stainless steel spacers are available in grade 304L. Carbon steel spacers are available with a thermoplastic powder coating for extra corrosion protection. Stainless steel and carbon steel spacers are available for pipe diameters 4″ – 144″.

Injection-Molded Polyethylene Spacers (Model CI)

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.

ApogeeAero® Roller Casing Spacers

APS offers patent-pending, ApogeeAero® Roller Casing Spacers with a revolutionary anti-corkscrewing feature specifically designed to fit into a smaller annular space while upholding higher load strengths than any other low-profile, high-load casing spacer roller offered on the market. Anti-corkscrewing rollers are available in 4 sizes, ranging from small to extra-large, with dynamic loads up to 6,000 lbs. and static loads up to 12,500 lbs. per roller. APS manufactures anti-corkscrewing roller casing spacers in various sizes to accommodate pipe diameters from 4 inches to 120 inches or larger and can satisfy specific customer requirements for practically every carrier pipe application, such as positioning multiple carriers or clusters with one casing, centering small carriers within large casing, positioning thermally insulated pipe without damaging the insulation, positioning gravity sewer to on-grade requirements, and much more.
These low-profile, high-strength anti-corkscrewing rollers are cost competitive to traditional runners while still cathodically isolating the carrier pipes from the casing pipe. Not only are they cost competitive, but they can carry heavy loads while reducing the coefficient of friction from .2 to .06 which is 70% less, thus increasing the average installation speeds from 3-5 ft. per minute to 15+ ft. per minute, reducing the size of equipment necessary to install carrier pipes & labor costs needed to push or pull carrier pipes. Carrier pipe pushes are installed 5 to 7 times or more faster than casing spacers with runners and require no greasing of the casing pipe I.D.’s as many contractors typically do.

End Seals

Advance Products & Systems End Seals outperform the costly and labor intensive brick and mortar method of sealing casing ends. While soil stress and pipe movement cause mortar to crack, the APS products move with the pipe insuring the integrity of the seal. And, unlike link-type sealing blocks that are limited to carrier/casing differential and can only be used on a concentric profile, the APS seals are totally flexible. APS offers four types of end seals which can accommodate any combination of pipe sizes.
End Seals Model
The models AC and AM are seamless and can easily be pulled on at the time of construction while the model AW wrap-around is designed to facilitate installation when the carrier line has already been welded together and the pull is complete. Simply wrap around the carrier and casing, remove the release liner from the two pressure sensitive butyl mastic strips and press the adhesive strips down to form a seal. Model AZ, zipper type end seal, wraps around the casing end and carrier pipe and zips shut to provide a tight seal while still allowing for pipe movement. All four are made of 1/8″ thick synthetic rubber assuring excellent chemical resistance and resiliency and are secured with T-304 stainless steel banding straps with a 100% non-magnetic worm gear mechanism to insure the integrity of the clamp. Only a screwdriver is required for installation.
In addition, Innerlynx form a mechanical seal between pipelines and casing. Innerlynx form a hydrostatic seal and electrically insulate the carrier pipe from the casing. Innerlynx can be installed by one person and require no special tools.
