The
ever expanding network of buried pipelines has led to
the development of
a specific system for the protection from the
corrosivity of the soil and the stray currents.
We
apply tapes both in our shops and in the field, to any
size of pipe and kind of special pieces.
The
system is usually based
on two layers plus an adhesive primer applied over a
blasted surface.
The
inner tape is designed for the corrosion protection and
made of a support layer of low/high density polyethilene
on top of which a butil
and synthetic rubber adhesive has been laminated.
The
outer tape is designed for the mechanical protection and
made of a support layer of high density polyethilene on
top of which a pressure sensitive adhesive has been
laminated.
The
above tapes are wrapped
with 1” or
50% overlapping in order to obtain a uniform
holiday free protection.
The
system is apt not only for straight pipes but also for
special pieces and for the joints protection to be
applied over the ditch.
It
is used for the preservation of buried gas, crude-oil
and water pipelines from the lowest ambient temperature
to the highest.
