For pressure testing and stopping all pipes, pipelines and pipe work fabrications from 2-72 inch (50 - 1800mm)

General

In addition to the ranges of Nylon and Aluminium plugs and Inflatable Stoppers, the Pipestoppers Division of Huntingdon Fusion Techniques Limited, also manufactures a range of Steel plugs from 2" to 72" in diameter.

These plugs are typically suitable for more arduous duties such as long immersion in water and use at higher temperatures or for contact with acidic or alkaline environments for which the Nylon and Aluminium plugs might be unsuitable.

The plugs are merely inserted into the pipe and the wing nut tightened to force the top and bottom plates together, thereby expanding the rubber ring to seal tightly in the pipe. The patented Friction Free washer enables easy tightening of the wing nuts.

The Steel Plugs are manufactured with 1/2", 1" & 2" outlets according to their diameters.

1/2" outlet for plugs up to 6" , 1" outlet for diameters 8" to 18" and 2" outlet for 20" and greater diameters.

The standard seals are made from natural rubber although special rubber seals are available for applications where greater chemical resistance and/or higher temperature applications.

(alternative rubber rings options are: Silicone, Nitrile & Viton)

All plugs conform to British Standards BS 8005 for low pressure testing and sealing of pipes.

DOUBLE LENGTH VERSION

A double seal can be even more effective for more arduous duties such as long immersion in water and use at higher temperatures or for contact with acidic or alkaline environments for which the Nylon and Aluminium plugs might be unsuitable.

The test pressure capability of the single stoppers is limited and the double versions increase that capability, while offering a greater stability in the pipe. As single plugs approach their pressure limits, they can tend to tip over like a butterfly valve. The double plugs will prevent the tipping and guarantee the seal.

They can be manufactured with 1/2", 1" and 2" outlets - call for more information.

The standard seals are made from natural rubber although special rubber seals are available for improved chemical resistance and higher temperature applications.
