New technology for PVC-O pipes
THE need for water infrastructure is
ever growing, but the economic situation
is forcing the lowering of the cost of
products and installation, transmitting
the pressure on installers and pipe
manufacturers.
At the same time, global warming has
pushed many governments to define
policies looking for more ecological,
environmentally friendly solutions on
every activity.
It is difficult to find solutions that
combine better performance, cost
reduction and lower CO2 emissions.
PVC-O pipes are perhaps the solution
that fits this difficult equation.
Molecular orientation is a physical
process that modifies plastic’s molecular
structure, where amorphous PVC-U
structure is reorganised into a layered
structured that confers mechanical
properties to plastic pipes that include
impact resistance, fatigue resistance
and flexibility.
PVC-O pipes are an environmentally
friendly solution for water transportation
according to the ‘Estimation of energy
consumption and CO2 emissions due
to production, usage, and final usage
of PVC, HDPE, PP and cast iron’ of
the Department of Engineering Projects,
Universitat Politecnica de Catalunya
(Barcelona, December 2005).
This report shows the CO2 emissions
and energy consumption during the
whole LCA (pipe’s life cycle), which
includes raw material production, pipe
manufacturing and usage life of pipes
for water transportation, comparing
PVC-O, PVC-U, PE and cast iron
pipes. The report concludes that
PVC-O pipes are the best choice for
water transportation.
Molecor Tech has developed an air
based technology in which no water is
involved, which makes a safer, cleaner,
more efficient process. It is a flexible
system able to work continuously with
an extrusion line, or to produce in
batches. The enhancement of the
mechanical properties results in less
consumption of raw material for the
same performance.
Less material means less oil
consumption, but also more hydraulic
capacity within the pipe, and more
efficiency for pipe installers.
Products manufactured by Molecor
range from DN 90 to 360mm and up to
25 bar, opening the way to new markets
for plastic pipes.
Molecor’s PVC-O technology allows
simple transformations of standard
PVC-U lines into PVC-O lines, bringing
savings for pipe manufacturers, and
benefits for potential pipe customers
and end users.
