 Gas Stopper Bags
Gas Stopper Bags are used to stop the flow of gas in steel, cast iron
and PVC gas pipes operating at pressures of up to 40Kpa. Heavy duty bags
are also available for higher pressure specific applications.
We have an extensive range of SARC gas stopper bags
that are suitable for most gas stopper applications.
| The Goodman Type gas stopper bag is
available in sizes 50mm and above and comes complete with a 450mm
long neck tube complete with a Shrader valve for inflation purposes.
The long neck makes it easy to insert the bag into a gas main
through a small hole drilled into the top of the main. This type of
stopper is used predominantly for stopping off mains operated at
pressures below 75Kpa and for larger diameter mains in excess of
300mm diameter. |

| The Wask type gas stopper is
designed to be used under no-gas conditions and needs to be used in
conjunction with the Wask Stopping or similar equipment and is
available in sizes 50mm to 350mm. This bag is used to stop off gas
mains operating at pressures up to 40Kpa depending on the main size. |

Swan Imports also have a range of Sarc Weld Purge bags
in a variety of sizes. The double bagging arrangement allows
for the introduction of an inert gas between the bags to create a gas
free space.
