Weld Purging small pipes of different diameters can be challenging, especially when budgets are tight. Often, welders are left to create their own homemade purging dams out of unsuitable materials such as foam, paper or cardboard.
Weld Purging Experts Huntingdon Fusion Techniques HFT® manufacture a range of low cost, lightweight Weld Purge Plugs for a variety of applications for pipe sizes 0.5 to 6” (12 to 152 mm) diameter.
Luke Keane, Technical Sales Manager for HFT® said: “Our Weld Purge Plugs make a great barrier for purging pipes. When you have to fill complicated pipework systems with inert gas, our Weld Purge Plugs are a perfect product to seal all holes and orifices for quality internal purging.”
“Typical purging applications for our Weld Purge Plugs include small or odd diameter pipes, short, complicated or variable size assembles where a purging system or inflatable dam would be too long or other purging equipment may not be available or practical.”
Manufactured from engineering quality nylon with rubber seals made of natural black rubber, special Plugs can be made to order with sealing rings made of silicone, viton or nitrile rubbers, making them suitable for use with petrochemical fluids, high temperatures or any other conditions that might arise during use.
The plugs are supplied with a hollow shaft with an outside ½” BSP thread for screwing on a standard hose connection or solid shaft versions up to 1.5” diameter for pressure testing.
HFT's Nylon Plugs can be used for many other applications, including garden ponds, pool and spas and on yachts. Other applications include the stopping of pipes to prevent foreign bodies or liquids from entering or gases and liquids from escaping, blocking pipes in order to carry out routine maintenance, repair work and leak testing. As “overnight stoppers” they provide a strong barrier in pipeline activities, to prevent foreign bodies entering the line during downtime.
