Nylon Weld Purge Plugs provide a great barrier for weld purging at a low cost.
For welding nickel and titanium alloys and stainless-steel tubes and pipe joints as well as stubs, elbows, and tees, Weld Purge Plugs seal all holes and orifices for quality internal weld purging. They can also be used for weld purging small or odd diameter pipes where conventional inline pipe purging systems may not be practical.
The plugs are made from engineering quality nylon up to 6-in. (152 mm) in diameter and will not seize up, rust or corrode. A friction-reducing washer inserted between the top plate and wing nut provides easy expansion and release.
They are also available in ready-made Weld Purging and Orbital Welding Kits containing the most common sizes of Purge Plugs used
- The hollow shaft plugs (1.5 to 6 in.) have an "0" ring seal around the stem to ensure leak tightness
- Can be used up to 167°F (75°C) continuously and 221°F (105°C) intermittently
- With special high-temperature seals, they can be used continuously up to 248°F (120°C)
