Weld Purge Plugs for tube and pipe purging
16 April 2021
For welding nickel alloy, titanium and stainless steel tubes and pipes, Huntingdon Fusion Techniques HFT® have designed and developed clinically clean, white nylon Weld Purge Plugs™, providing a great barrier for weld purging.
Luke Keane, Technical Sales Manager for HFT® said: “When other purge systems cannot be used, Weld Purge Plugs™ can be used to make a suitable barrier for purging pipes, tubes or fittings.”
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.
Typical applications for Weld Purge Plugs™ include small 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. HFT®’s Nylon Plugs can be used for many other applications, including garden ponds, pools 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.
