Large bore saddle
Plasson’s Large Bore Saddle is a
solution for connecting pipe diameters
of 250 to 800mm, with an outlet of
between 90 and 160mm.
Assembling and welding the saddle
from start to finish takes around one
hour. The Large Bore Saddle has a
function that enables the installer to test
the welding before cutting the pipe. The
test gives a high degree of certainty that
the installation has been done correctly,
while testing quality and pressure,
immediately following the installation.
This avoids the risk of expensive and
time-consuming mistakes resulting from
tapping incorrectly welded saddles.
The advanced solution includes a single
welding time for ambient temperatures
between -10°C and +45°C, with no
temperature compensation required, no
need for preheating process, instant
heat transfer between coil and PE to
speed up and improve gap closing, and
a full bore outlet SDR11 – 90, 110, 125
and 160mm.
As with all Plasson ElectroFusion
solutions, the Large Bore Saddles
use a SmartFuse system to ensure
a fast and easy welding process,
and full traceability of the fitting and
components to ensure quality control.
The Large Bore Saddles are designed
according to the specific needs of the
end-users, keeping in mind the field
conditions and limitations, ensuring a
simple installation that will be safe and
secure.

Double wall piping system
Asahi/America has reintroduced
the Poly-Flo® co-extruded double
containment piping system. Available in
black PE and euro grey PP-R, Poly-Flo
is suitable for installations with space
constraints and systems where thermal
expansion and contraction are present.
Poly-Flo is a complete system that
includes full pressure fittings, drainage
fittings and machined fittings.
The SDR-designed system is available
in 1 x 1½", 2 x 3" and 4 x 6", and
operates up to 150psi at 68°F.
Because of its unitary construction,
Poly-Flo pipe and fittings act like a single
wall system, which helps prevent failures
often seen in fabricated systems. This
is especially important in installations
with fluctuating temperatures, or
applications such as directional drilling
where opposing forces
act on the carrier and
containment pipes.
Black PE Poly-Flo is suited
to outside, above-ground
applications because
of its UV resistance,
and it performs well in
underground installations
because of its resistance
to crack propagation.
Due to its high pressure
rating, euro grey PP-R
Poly-Flo is suitable for applications
running at higher temperatures.
Water treatment facilities and chemical
applications can benefit from Poly-
Flo’s chemical resistance. The system’s
low cost and easy installation also
make it suitable for drainage systems,
pressurised transfer lines, and industrial
applications requiring up to a 4" carrier
pipe.
The Poly-Flo double containment piping
system is available with manual and low-
point leak detection sensors. Joining the
upgraded system only requires standard
welding equipment; no special clamps
or inserts are necessary. Asahi/America
offers butt fusion welding equipment
and weld training for all of its piping
systems.
