Sava 529414 64"-80" Multi-Size Pillow Style Large Diameter Inflatable Pipe Plug Product Guide

Pipe Plug Selection Notes

This pillow-style inflatable pipe plug fits nominal pipe diameters from 64 to 80 inches, offering a versatile multi-size range. Selecting this plug requires verifying pipe condition and internal surface irregularities, as the NR-SBR rubber reinforced with Kevlar tire cording depends on correct seating against the pipe wall. Confirm backpressure against the size-specific chart or manual for the selected pipe diameter, and keep that check separate from the specified inflation pressure. The inflation pressure needed for setting the plug is distinct from backpressure limits and should be planned separately for secure placement.

Pipe Access And Setup Planning

For large-diameter pillow plugs, inspect the rubber surface carefully before each use for cuts, abrasions, or cracking, as damage can lead to failure under pressure. Use protective sleeves as needed when pipe-wall conditions are rough or abrasive during insertion or retrieval. Inflation pressure should be inflated to the specified level and regularly monitored while in place; these plugs are not intended to remain inflated and unattended for extended periods. Plan for correct blocking or restraint to counteract pipe pressure per user manuals, and confirm that any chemical exposure or elevated temperatures encountered are compatible with the NR-SBR rubber formulation before operation.
