Atlanta Molecor

PVC- O Pipes and Fittings

Atlanta PVC-O are the most advanced pipes for the conveyance of high-pressure water currently available on the market, with a number of exceptional features for this kind of application, thanks to the process of Molecular Orientation.

PVC is essentially an amorphous polymer in which the molecules are located randomly. However, under certain conditions of pressure, temperature and speed, by stretching the material, it is possible to orient the polymer molecules in the same direction as which the material has been stretched.

Depending on the process parameters used and mostly stretch ratio, a higher or lower orientation degree will be obtained. The result is a plastic with a layered structure which layers can be seen at a glance.

Advantages:

► Unbeatable Impact Resistance – Atlanta Molecor pipes have a high resistance to shock. This means that are minimized breakages during installation or during on-site trials caused by dropping or by impacts from stones.

Furthermore, Molecular Orientation prevents the propagation of cracks and scratches and eliminates the risk of rapid crack behavior. The result is a spectacular increase in the product’s useful life.

► High short- and long-term hydrostatic resistance – Atlanta Molecor pipes offer a resistance to internal pressure of up to two times the nominal pressure (32 bars in PN16 bar pipes or 400 psi in PN200 psi), which means they can bear sporadic excessive pressure such as water hammers and other malfunctions in the network.

Moreover, the material creep behavior is very low, ensuring the durability of the pipe working at nominal pressure for over a hundred years.

► Excellent response to water hammers - TOM® pipes offer lower celerity than other piping systems (four times less than ductile iron pipes), which means less water hammers caused by sudden variations in water volume and pressure. This reduces and almost eliminates the possibility of breakage during opening and closing in the water network and when pumping gets under way, protecting every component of the network.
