Twin Walled Pipe, also known as pipe in pipe or bunded pipe. Are becoming industry standard for underground petroleum, fuel oil and chemical pipework requirements. UPP from Franklin Fuelling is a HDPE (high density polyethylene) pipe. Both inner and outer pipes are made from HDPE to add extra protection to the environment. Our qualified installation engineers, certified by Franklin Fuelling, can install the UPP pipework system. Complete with leak detection capability and the highest levels of environmental protection. Double wall, pipe in pipe manufactured in HDPE has many advantages over the traditional stainless steel pipe with mechanical joints. These include:
Longer coil lengths (upto 100m) allows for less joints. It also allows for sweeping bends - again less joints
Less joints mean less points of failure in piping systems and a more reliable fuel system!
Electrofusion welding 'Gemini System' for fast installation & strong assemblies which allows direct burial with no need for inspection chambers.
HDPE is corrosion resistant
Integral EVOH liner gives great chemical compatibility for hydrocarbon and alcohol based fuels.
Smooth bore gives low resistances for efficient pumping.
Unique system brings unmatched resistance to ground movement.
'Over Pressure' leak detection for the highest levels of environmental protection and monitoring.
The primary pipe allows for the safe transport of fuel within the fuel delivery system. The principle function of this is to connect the heating oil tank to the dispensing pumps or appliances being supplied. The flexible pipe and fittings allow for curves and gradual bends to your storage tank. However where branches are required, Tee fittings and elbows are available. The continuous secondary outer allow an over pressure leak detection system to be used. This provides the ultimate in environmental protection and monitoring standards.
