UPP® SEMI-RIGID
PIPEWORK SYSTEM
Since its introduction as the world’s first electrofusion pipework
system for fuel applications over thirty years ago, UPP®
semi-rigid pipework has become known globally as the standard
for liquid tight pipework systems. UPP® pipework utilizes the
advanced electrofusion welding process to effectively bond
system components together into one, leak proof system.
HIGHLIGHTS
• The highly efficient electrofusion welding process that
connects pipe, fittings, boots, and containment to create a
seamless direct burial pipework system.
• The UPP® electrofusion welding process is safe and simple
to complete in any climate and virtually any weather
condition. An installer simply preps the components, fits
them together attaching welder leads to the fitting, and
then presses a single button on the welding unit to initiate
the process.
• The welder unit itself calculates the exact settings required
to complete the weld, regardless of the pipework diameter
or temperature, leaving no settings for the installer to input.
• Available in both coils and straight sticks, UPP® pipe can
accommodate the sweeping bends of a “loop” pipework
system while the straight sticks make installation between
dispenser sumps simple by providing a square pipe entry
into containment.
• The flexibility of UPP® double wall semi-rigid pipe allows for
easy installation through existing ducting.
• As a vital component to the UPP® pipework system,
patented UPP® electrofusion entry boots weld directly
to the wall of any polyethylene sump creating a watertight
seal between the pipework system and containment spaces.
• UPP® double wall semi-rigid pipe is flexible enough to coil
and bend like flexible pipe, while UPP® single wall pipe is
also rigid enough to be used in place of fiberglass pipe for
vapor or vent lines.
