Inflatable pipe plug for welding purge applications PipeStoppers
50 mm - 150 mm (2" - 6")

Pipestoppers™ Inflatable stoppers
INFLATABLE STOPPERS
These versatile inflatable air bags and stoppers are used to accommodate a wide variety of industrial applications, most commonly used for:

Plumbing operations
Ideal for creating an air-tight seal in drainage applications
Low pressure hydrostatic tests
On-site thermoforming of bends in ducting and conduit materials
Fibre-optic construction projects
Concrete Pipe Joint Testing
Debris and Animal Stopping
Weld purging to isolate large volumes in tanks, so minimum volumes are left for argon/nitrogen purging

Features:
Inflatable air bags up to 2,000 mm (80") diameter
Manufactured using a high quality latex inner tube and polyurethane impregnated nylon fabric outer cover
Installed with a length of flexible inflation hose with sealing tap/valve.
Styles:
Cylindrical inflatable stoppers do not 'turn over' in the pipe. They are commonly used for stopping off pipes, particularly where access is difficult. They are frequently used for testing new pipes and drains.
Spherical inflatable stoppers give less contact area than the cylindrical version, but are very useful when access is limited. Since the position of the inflatable stopper in the pipe is not critical, it can be put at any angle. This is particularly useful when inserting into a small opening at the top of a pipe, rather than at the end of the pipe.
Rectangular inflatable stoppers have various applications specifically in air conditioning systems, air ducting and venting.
All sorts of special shapes and sizes have been taken on as specials!
