PVC-O: a revolution in pipes
PVC-O pipe is considered a high
performance product, yet its application
has not been as extensive as might have
been expected. Technical limitations
and poor efficiency in manufacturing
processes were obstacles to the wide
application and use of PVC-O pipes.
However, these limitations have been
overcome, and the new air process
of molecular orientation developed
by Molecor provides an efficient
manufacturing process, widening the
range of product to high pressures
and large diameters, and opening new
markets.
Molecor PVC-O pipes are obtained
from conventional PVC pipes after the
molecular orientation process. This is
a physical process that stretches the
material and, under certain conditions
of pressure, temperature and speed,
reorganises the polymer molecules,
achieving a laminar structure.
This new alignment brings strength and
confers other mechanical properties,
including impact resistance (molecular
orientation prevents the propagation
of cracks and scratches and reduces
the risk of rapid crack behaviour);
hydrostatic resistance – up to twice
the nominal pressure; and excellent
behaviour to the effects of water
hammers. It is also claimed to provide
higher hydraulic capacity: between 15
and 40 per cent more than pipes made
from other materials and with similar
external diameters.
