Huntingdon Fusion Techniques (HFT®) has designed and developed white Nylon Weld Purge Plugs, providing a barrier for weld purging at a low cost.
Made from engineering quality nylon up to 6 (152 mm) diameter, Weld Purge Plugs will not seize up, rust or corrode. A friction-reducing washer inserted between the top plate and wing nut provides easy expansion and release.
For welding complicated nickel alloy, titanium and stainless steel tubes and pipe joints, as well as stubs, elbows and tees, Weld Purge Plugs are a perfect product to seal all holes and orifices for quality internal weld purging, said Luke Keane, technical sales manager for HFT®. They can also be used for weld purging small or odd diameter pipes where conventional inline pipe purging systems may not be practical.
HFTs Weld Purge Plugs are also available in ready-made Weld Purging and Orbital Welding Kits, which contain the most common sizes of Purge Plugs used.
