Will Even Pass Through Small Pipes!

HFT Pipestoppers Inflatable Stoppers


The versatile Pipestoppers® Inflatable Stoppers can be inserted and retracted through small holes and then inflated to full size for stopping operations. They are used to service a wide variety of industrial applications and are available in the following ranges:

Standard Inflatable Stoppers:

Cylindrical Inflatable Stoppers

Spherical Inflatable Stoppers

The Standard Range of Inflatable Pipe Stoppers are available for immediate delivery with sizes ranging from 1 to 96" (25 to 2440 mm).

Cylindrical Inflatable Stoppers will not invert (turn over) inside a pipe when under pressure, because they are longer than their diameter.

Spherical Stoppers are used where the position of the stopper is not important and they can be put at any angle and still make a seal.

12W Pipestoppers Heat Resistant Covers Inflatable StoppersChemical / Heat Resistant Inflatable Stoppers:

PetroChem Inflatable Stoppers

Heat Resistant Inflatable Stoppers

The PetroChem Inflatable Stoppers are identical in appearance and performance to the Standard Inflatable Stoppers, except that the inside inflatable latex part is enclosed in a thin, flexible rubber that is resistant to the petrochemical fluids and vapours.

Heat Resistant Inflatable Covers are available with a performance rating to give protection up to a temperature of 300°C (572°F).

HFT®'s Pipestoppers® most common applications are:  

Debris stopping during machining operations

Leak testing of pipework systems in commercial, domestic and industrial applications

Low pressure hydrostatic tests

On-site thermoforming of bends in ducting and conduit materials

Fibre-optic construction projects

Debris and animal barriers for overnight protection of pipelines

Weld purging to isolate volumes in tanks, to minimise gas purging volumes

Plumbing operations

Frequently Asked Questions

Pipestoppers Inflatable Stoppers Pipe Plugs

1.0 How do I know when to choose between a Mechanical and an Inflatable Stopper?

HFT Pipestoppers® Inflatable Stoppers can be inserted and retracted through holes smaller than the one to be sealed. They are much less expensive than mechanical stoppers, but are not so suitable for applications requiring the ruggedness and strength of a mechanical stopper. 

2.0 How do I prevent the stoppers from being pushed out of the pipe during a pressure test?

It is common to brace the ends of pipes to prevent stoppers sliding out. The Pipestoppers® Division of Huntingdon Fusion Techniques HFT® can provide further data.

3.0 Will your stoppers be suitable for use in petrochemical pipework where there are hydrocarbon liquids and gases present?

The HFT Pipestoppers® Division manufactures special Inflatable Stoppers for the petrochemical industry where long term resistance to chemicals and / or petrochemical oils and vapours is necessary.
