“In machining applications,
they can be inserted below a
horizontal flange on a vertical
pipe, to prevent machining fluid,
swarf and tools from falling into
expensive machinery such as
pumps and turbines etc.”
“When welding large tanks and
vessels, stoppers inflated with
air can dramatically reduce the
volume inside, so that the argon
purging process takes little
time and uses the minimum
of expensive gas. The stoppers
can pay for themselves in one
weld or application and can
be used multiple times. Other
applications include leak testing
of pipework systems, whether
commercial, domestic or
industrial, in pipes made of any
materials.”
All Inflatable Stoppers are
manufactured with a strong
internal latex balloon covered
in a waterproof polyurethane
coated nylon bag for low friction
and to prevent the production
of static electricity or accidental
sparking.
Inflatable Stoppers are
particularly useful when one
or more can be inserted into a
small opening close to a work
location, rather than at the end
of the pipe, tank or vessel. No
high-pressure equipment is
needed for inflation.
The standard range of
Inflatable Stoppers is available
for immediate delivery in
Cylindrical or Spherical formats
with sizes ranging from 1 to 96”
(25 to 2,440 mm).
Inflatable Stoppers are available
with heat resistant covers to
protect them against high
temperatures. HFT® also has
a range of Rubber Inflatable
Stoppers that are suitable for
petrochemical applications and
are resistant to all hydrocarbon
fluids and gases.
