Stainless steel fittings,
flanges, tubes and valves
Advanced Fluid Technologies supplies
stainless steel hydraulic, pneumatic
and industrial-based engineering and
pipeline products to the OEM, end-user
and distribution markets.
Products include pipe and tube, DIN
2353 compression couplings, flanges
(BS4504, BS1560, BS10 Table, SAE
and CETOP), 150lb screwed fittings,
twin ferrule compression couplings,
hydraulic adaptors (BSP, BSPT, NPT,
JIC, SAE and ORFS), ball valves (low
and high pressure), and accessories
(gaskets, O-rings, seals and washers).
Special focus is given to a complete
range of SAE and CETOP flanges to
ISO 6162 and ISO 6164, in both mild
and stainless steel: SAE 3000 from 3/8"
to 5"; SAE 6000 from 3/8" to 3"; and
CETOP from 3/8" to 8".
To further complement its flange port-
folio, the company offers a range of
three- and four-bolt gear pump flanges.

Pipe sealing plugs and stoppers
The Pipestoppers® division of
Huntingdon Fusion Techniques has
released a set of literature describing
its range of pipe sealing plugs and
stoppers.
These accessories can be used for low
pressure water or air testing of pipe
systems in the water, gas, oil and other
fluid industry pipe work, as well as
for debris stopping during machining
operations or overnight stopping for
temporary closure of piping systems.
All plugs conform to British Standard
BS8005 for low pressure testing and
sealing of pipes.
The mechanical plugs are simple to
work with and install with a wing nut
that rotates on a friction-free washer
to compress the two plates together,
expanding the natural rubber tyre to
seal tightly inside the pipe or other
chosen orifice.
For high temperature and aggressive
applications the natural rubber rings can
be replaced with silicon, nitrile or Viton
rings as appropriate.
The Aluminium range plugs are strong
and durable, non-rusting and are
negatively buoyant so that they can be
used subsea.
They are available for 1.5" to 36" pipe
sizes, whereas the lower-cost steel
plugs are available for 1.5" to 96"
diameter pipes. However, the aluminium
plugs are suitable for more arduous
duties such as immersion in chemicals
and use at higher temperatures.
All plugs and stoppers can be used
to seal manholes or pipework entries
so that during transportation of large
vessels, like fractionation columns or
heat exchangers and other vessels
or tanks, all entries and exits can be
blocked off to keep inert gas trapped in
or to keep contaminating air and fluids
from entering.
The Nylon range plugs, with sizes
from 0.5" to 6", are used for clinical
applications as well as in the food, dairy,
nuclear, shipbuilding, aerospace, water
and gas industries to form a leak-tight
seal inside tubes, pipes or orifices for
leak testing, closure or weld purging.
Inflatable plugs and stoppers for
all diameters are also in the HFT
Pipestoppers range. The inflatable
versions are available in different
shapes to cater for a range of industrial
and commercial applications. Inflatable
stoppers can be inserted through small
holes and expanded to maximum sizes
inside.
Other plugs, stoppers and inflatable
systems are available for use with – or
containment of – drinking water and
aviation fuel, for example, and can be
used with other fluids or gases as
appropriate.
