Low Cost Weld Purging
with Weld Purge Plugs™
Weld Purging smaller tubes and 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.
Huntingdon Fusion Techniques HFT® have
designed and developed clinically clean, white
Nylon Weld Purge Plugs™, providing a great
barrier for weld purging at a very low cost.
Luke Keane, Technical Sales Manager for HFT® said:
“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. They can also be used for
weld purging small or odd diameter pipes where
conventional inline pipe purging systems may not be
practical.”
The Tandem Systems isolate a small volume either
side of the weld to reduce inert gas costs and to bring
the weld purging time down to a fraction of what it
might take using other kinds of dams and unsuitable
materials.

Weld Purge Plugs™ are made from engineering
quality nylon up to 6” (152 mm) 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.
The low cost, lightweight Weld Purge Plugs™ are also
available in ready-made Weld Purging and Orbital
Welding Kits containing the most common sizes of
Purge Plugs™ used. Each kit has a strong robust ABS
plastic case, with custom foam inlays for storage and
quick location of the plugs where needed.
Huntingdon Fusion Techniques HFT® also design
and manufacture a Range of Tandem Weld Purging
Systems in sizes 1” to 88”, producing oxide free welds
time after time.
