Description

AZ non-metallic casing spacers are designed for use with water and sewer pipes 3.85” to 13.75” in diameter. They are an economical alternative to banded woods skids and stainless steel bands for inserting pipes into casings. AZ spacers also eliminate the need for sand or grout filling of the annular space in the casing. All are adaptable to a wide variety of carrier pipe O.D.’s found on PVC Pressure/Sewer Pipe, DI-Ductile Iron, C-900, P.E., and IPS-Steel Pipes




Typical Application




Typical Installation
Based on 20-feet (6.0-meters) carrier pipe segments in a casing of not more than 300-feet (91.5-meters) . Consult PSI for longer casings and for concrete pipe.

Recommended Maximum Spacing
All Model AZ Isolator/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.



Benefits/Features

  • Variable O.D.’s of casing spacer to fit multiple sized space
  • Manufactured from UV resistant polypropylene
  • Runner heights may be interchanged or field cut to adjust for grade
  • Corrosion protection - only metal components are steel bolts/nuts
  • One piece molded construction for maximum load bearing
  • Allen Head Bolts for improved spacer tightening

Typical Specification

Designed for 3.85” through 13.75” O.D. carrier pipes. Casing spacers shall be AZ segmented type molded in high density UV resistant polypropylene. Each spacer segment shall be a, “non-welded” molded piece designed for accommodating variable pipe O.D.’s by attachment of the required number of segments. Minimum spacer width shall be 5.2” (132mm). Runner height shall be sized correctly to provide adequate pipe support without the bell or joint contacting the casing during installation. Approved ISO 9001:2000 Manufacturer: Pipeline Seal & Insulator, Inc., Houston, Texas, U.S.A.

End Seal Specification
After insertion of the carrier pipe in the casing, the ends of the casing shall be closed by installing a PSI Model "C", Model "S" or Model "FW" casing end seal as manufactured by Pipeline Seal and Insulator, Inc., Houston, TX.

Link-Seal® End Seal Specification
(Carrier Pipe Must Be Centered Within Casing)
After insertion of the carrier pipe in the casing, the ends of the casing shall be closed by installing the Link-Seal® end seals and a 1/8" thick synthetic rubber end seal equal to the PSI Model "C" end seal. Both as manufactured by Pipeline Seal and Insulator, Inc., Houston, TX.
