A heavy-duty pneumatic pipe sealing plug for isolating and pressure testing very large-diameter pipes from 600 to 1,200 mm — inflated with standard compressed air at a reduced inflation pressure of 1.5 bar.
Key Features
-
-
- 600–1,200 mm usable range — suits very large-diameter pipe applications across major civil and infrastructure projects
- 1.5 bar (22 psi) inflation pressure — lower than smaller models; do not exceed inflation pressure
- 1.0 bar maximum back pressure — at 600 mm pipe diameter; back pressure rating reduces with increasing pipe size
- Supplied with ARO air couplers — compatible with standard compressed air supplies
- 38 kg unit weight — mechanical assistance or multi-person handling required for safe insertion and retrieval
-
Typical Applications
-
-
- Pressure testing of newly installed pipe sections
- Isolating flow for maintenance and repair work in large-diameter mains
- Diverting lines to bypass damaged or active sections
- Suited to stormwater, wastewater, and water supply infrastructure
- Suitable for all pipe materials — concrete, PVC, clay, steel, and HDPE
