Elements that were created for each other

Where hot and cold water needs to needs to be safely and reliably transported,'IPETECH PPRC pipes made form Polypropylene Random Copolymer provide the optimal solution,

Easy installation, cost-effective in use
Whatever the complexity of a Domestic water installation. PIPETEC.H' PPRC pipes have the ability to be shaped to confirm to even the most complex layouts_ Their easy weldability and impact resistance also makes them faster and simpler to install.

A lifetime of service that means what it's says
For water and heating designers and installers, PIPETECH' PPRC p made from Polypropylene Random Copolymer mean solutions can be created which provide long and reliable service-without compromise to the environment in which they are used.

Excellent Stability
In use, the formulation of PIPETECH" PPR pipes made: iron) Polypropylene Random Copolymer is such that it offers a high molecular weight, plus excellent mechanical properties. Additional benefits include high levels of heat stability as well as excellent resistance to extraction. These qualites contribute to ensuring that Crown PPR pipes conform the stringent demands of diffo uj DIN specifications of domestic water requirements, They also mean that an exceptionally long and service life is assured.

A performance that lasts...and lasts
Polypropylene Random Copolymer is a random copolymer, It's properties are such that PIPETECH PPRC pipes extruded from Polypropylene Random Copolymer, can withstand temperatures up to 70 C, without losing shape. They can also handle short duration temperatures of up to 100 C Combined with good chernicaf resistance and impact strength, PIPETECH' PPR pipes can simply be installed... and forgotten about for at least years! Particularly important for domestic water installations, is theltact that Polypropyene Random Copolymer is also physicologically harmless and is taste and odour neutral

Meeting demanding specifications
Crown Pipe PPR pipes and fittings made from Polypropylene Random Copcfymer conform WIN 8077178 and DIN 16962 respectively. System standards for particular applications are applied on an international basis. This means that perfomance requirements for hot and cold water PP pipes for example arc covered by prEN 12 202 (the same as ISOrDIS 15 874). in terms of two different application (see Table 1)- each of which also determines pipe diameters­ Together. these factors mean that with the right choice and dimension of pipes, a service life of at least 50 years can be achieved without difficuty whatever the installation.

The Physiology of success

Water is not only elements that Polypropylene Random Copolymer has to react positively with. Physiological properties, UV radiation, plus compatibility with metal components, all play important roles in ensuring safe and reliable water management.
