    Originally, preinsulated pipe systems were
    developed specifically for district heating, but in
    recent years the advantage of the basic ideas of
    preinsulated pipes have proven so clear cut that
    preinsulated pipes are equally important in providing
    district cooling. The demand for cost-effective
    systems and reductions in environmental burdens
    have boosted demand for more comprehensive
    cooling systems.
    Using preinsulated pipe systems to transport cooling
    power presents a series of challenges.

The four basic components of any preinsulated
pipe are the carrier pipe, the insulation, the casing
pipe and the joining socket. For all of these com-
ponents, Eurapipe K-FLO product utilises materials
readily recognised as world’s best for each respec-
tive component function.
         ABS’s retention of its robust physical
     properties at cold temperatures (operating range
     is -30° to 60°C) makes it the ideal thermoplastic
     piping system for chilled water applications for
     both below and above ground and no matter
     whether it is for insulated or non-insulated

     ABS carrier pipes have an appraised life
     expectancy in excess of 50 years with no
     significant increase in flow resistance.            welding provide a jointing system that’s reliable,
                                                         repeatable and robust in an extremely wide range
                                                         of jointing conditions.

        CFC free polyurethane (PUR) cellular foam
     between the carrier pipe and the casing jacket
     provides the vital element in ensuring optimum
     energy conservation of a preinsulated pipe
        ABS’s superior structural strength,
     resistance to high loads and complete corrosion
     resistance provide an excellent and durable
     casing material for buried and above ground
        ABS’s superior mouldability and
     machinability to exact tolerances and its
     exceptional suitability to solvent cement
