PESTEC NOCX pipes will be used on new Audubon Bridge
crossing Mississippi river near Baton Rouge in Louisiana.

More than 20000 m stay cable pipes for the 482 m main
span bridge with the 2x 153 m pylons are needed.

Owners and designers approach is to design the bridge
similar to the approach of 19th century local residing, very
renowned artist John James Audubon, who dedicated his
life to paint all of the birds in America also valuing smallest
details and their relationship to the surrounding
environment.

Mr. Audubon inspired the engineers to the goal to ensure
the bridge is not built in a vacuum, so rather to get an
integral part of the surrounding landscape.
So the theme selected for this project is ‘In harmony with
nature’.

The stay pipe color is burnt umber, a common color found
in the birds native to this area and has the advantage to be
even visible to the travelling public against cloudy or hazy
sky, so at all weather conditions.

PESTEC is proud to supply their NOCX pipes for this bridge
‘In harmony with nature’.

PESTEC introduce advanced PUR HMD polyurethane quality
optimized for hydrolyse resistance microbe-resistance, low
temperature resistance by also absorbing dynamic stresses
in outdoor use.

First advantage is a new production technology for this
material needing More simple tools only and so saving high
injection tool costs as needed for other material. Either
small quantities of individual shapes, e.g. like for stay cable
boots, now can be offered for affordable prices.

Second advantage is the availability of a big variety of
colors.

Compared with CR – polychloroprene (common brand
name Neoprene) and CSM – chlorosulfonated polyethylene
(common brand name Hypalon) our PUR HMD material
provide excellent weather resistance in black color
and good weather resistance in other colors where CR and
CSM only reach medium to good results.

While wear resistance of PUR HMD is better, all other
mechanical properties like tensile strength, aging, ozone,
abrasion, temperature range and compression set are
very similar with CR and CSM.

PESTEC’s Visco elastic gel of epoxy polymer is an invention
for long term corrosion protection of high performance
materials in civil structures.

The material has been successfully used on several projects
e.g. for stay cable anchor protection.

Special formulated Gel Epoxy resin and hardener
components are mixed at ambient temperatures, easily
injected to smallest cavities because of it’s high viscosity
( like water) with low pressure during 12-24 hours and
cross linked during polymerization to a visco elastic
polymer with adhesive properties as well as damping
properties to the system.

Perfect corrosion protection has been approved by several
tests, e.g. 3 month exposure in salt spray test and salt-
water immersion test as well temperature test. In addition
PESTEC Gel Epoxy provide excellent alkaline resistance
during 6 month cement grout compatibility test and
excellent mechanical behaviour in cycle thermal test.

It was further approved to stop started corrosion at it’s level.
Other benefits are volumetric material shrinkage, no
material diffusion to other materials and no temperature
increase during polymerization.

Installation is easy and fast. It needs just to drill a hole
into the steel duct, to heat up the HDPE grout port same
as in our well experienced grout port welding system, to
fix heated grout port in the steel duct and to spread it by
using our special tool. The HDPE grout port is tight
and tough fixed in the hole and can not be removed.

Standard spiral corrugated vent pipe 21/28 mm can be
connected to the grout ports. Modified grout ports to fit
to smooth vent ducts or other customized solutions
can be offered.

To protect both sides of the 2500 m long and 10 m
high facade of the railway approach of historical
Antwerp Railway Station from year 1905 still in
operation today, the new HSL - High Speed Railway
Station is designed on underground levels under
the present rails.

Construction method are tunnel works using
prestressed beams and excavate the ground part
by part to reach -2 level underground.

More than 17000 m PESTEC IP 3 M PP Duct of
sizes ID 85 and ID 100 have been installed for
corrosion protection of internal post-tensioning of
the beams. To complete the corrosion protection
system, PESTEC PF duct couplers, grout ports
welded to the ducts, as well as vent pipes, valves
and end caps have been used for perfect grouting.

IP 3 Duct approval was achieved by meeting the
strict project requirements.

We proudly received the first contract worldwide using OD
400 mm HDPE pipe to cover the biggest stays ever used.

7000 m NOCX HDPE pipe OD 400 mm SDR 21 including
external spiral in grey color will be installed on a US bridge
in the state of Maine starting April next year.

For this new size a new tool for the external spiral needs
to be produced.
We will also supply several components in the same
grey color to complete the system.

Our very well matured pipes, already providing
extraordinary features in uv stability, heat and micro
crack resistance on more than 100 projects worldwide for
very competitive price, were chosen from the project
designers, project engineers as well the subcontractor
as the most efficient and economical solution to protect
the strands and cover them long term in favourable design.

Thank you to our customer for this contract as well as for
the extension of our product line !!!

Choice of more than 200 colors including metallic effect

e.g. in national colors, State colors or colors of province
or city.

As an option the double spirals are offered in one or two
different colors from the pipe color.

Colored external spirals are of same best NOCX HDPE
quality incl. uv stability, heat and micro crack resistance
and online welded to the pipes.
