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
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 bags which do not 'turn over' in the pipe.
Spherical bags which are ideal to insert through a small hole + seal a large diameter pipe.
Rectangular stoppers for ducting.
Heat Protected Stoppers.
Concrete Pipe Test Stoppers.
All sorts of special shapes and sizes have been taken on as specials! |

Anti-pollution stopper
Pronal anti-pollution stoppers have been designed to remain permanently fitted in water and sewer pipes so as to quickly stop the pipeline when accidental contamination occurs.
To do this, simply trigger stopper inflation using a remote-operated system.
Once inflated, it will prevent any toxic fluid spill or spreading of firefighting water in the pipeline. |

Float-in Bags are fitted with a reinforced front cover and tension lugs. The CR material ensures increased resistance to chemicals. Working lines are secured to the tension lugs using carbine hooks and the pipe sealing bag can be floated into the pipeline without any difficulty.
Only four sizes are needed in order to seal pipe dimensions ranging from 70 mm to 1200 mm (2.8 inch to 47 inch). The float-in bag program is rounded off by a chemical variation in addition to the basic design.
In this case, all metal parts on the float-in bag are made of stainless steel and the integrated inflation hose (10 m/32 ft.) guarantees the corresponding safety distance to the area of danger. |

An Expansion joint of rubber is a made flexible union with natural or synthetic elastómetros, weaves of reinforcement designed to compensate extensions and contractions by temperature variations, damping and absorption of vibrations in facilities of transmission of fluids.
The problems of vibration, noises, shock, corrosion and tensions can be solved early incorporating the Expansion joints of rubber in the systems of conduction of fluids. |
