Sava 529491 75"-88" Multi-Size Pillow Style Large Diameter Inflatable Pipe Plug Product Guide

Pipe Plug Selection Notes

This pillow style plug covers a wide nominal pipe diameter range from 75" to 88", allowing use across multiple large-diameter pipes with a single plug. When selecting this plug, verify the specific pipe diameter to confirm correct fit and sealing performance within that multi-size range. The NR-SBR rubber composition reinforced with Kevlar tire cording offers strength and flexibility, but for applications involving chemical exposure, consider whether a chloroprene chemical-resistant version may be needed. Confirm backpressure against the size-specific chart or manual for the selected pipe diameter, and keep that check separate from the specified inflation pressure.

Inflation And Blocking Planning

Before use, inspect the plug carefully for any damage such as cuts or abrasions in the rubber, which can increase the chance of failure under pressure. Use protective sleeves when pipe conditions or abrasions could harm the plug during insertion or removal. Inflate the plug to the required pressure and monitor inflation pressure regularly during use, maintaining it as specified since long unattended inflation is not advised. Plan for adequate blocking or mechanical restraint based on the job’s expected backpressure and directional forces; follow any user manual guidance for bracing.
