Stainless Steel Band Casing Spacers, Model SSI, by APS
Description
Heavy duty two-piece stainless steel bands serve practically every piping application and should be utilized inside casing that is 2 or 3 sizes larger than the carrier pipe.APS stainless steel band casing spacers are available in two models: the SSI8 model, which is 8” in width and recommended for carrier pipe 4” to 24”; and the SSI12 model, which is 12” in width and is recommended for pipe 26” to 120” and larger. Stainless steel band spacers are recommended for every 6 to 8 feet of pipeline.
For larger diameter pipelines and bell and spigot applications, APS Spacers are available with runner/risers to provide an extra margin of safety. The bands are constructed of 14 gauge stainless steel with a 0.090” EPDM liner. Stainless steel spacers are available in grade 304.
