News 34 Longest USA Stay Cable Bridge approaching ‘In harmony with nature’ 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’.

News 23 Information on new UV-Test PESTEC present updated detailed test information on a uv-test called SEPAP and which we noticed in some project specifications in the past. Focus is the prediction of long term polymer stabilization based on extreme short time acceleration. We did test our NOCX pipes in this test 2 times in the past and due to the partly different test results versus our standard Xenotest and WOM tests we searched for the reasons therefore. SEPAP test did not reach international acceptance up to now and has not been approved from experts for an international norm. Main reasons seem to be the use of non-natural light radiation with very high energy causing molecule absorptions, polymer and additive damages and excessive polymer oxidation. See detailed information: SEPAP Test Information.PDF PESTEC propose to stay with the reference standards Xenotest and WOM Tests according international accepted ISO and ASTM norms as reference tests for accelerating photo-aging test for long term uv-stability prediction of HDPE pipe products.

News 5 OIT Test for IP 3 PE and PP ducts acc PTI requirements passed We successfully passed OIT test executed at independent german laboratory acc ASTM D 3895 performed on our IP 3 PE and PP ducts acc. Latest PTI requirements to provide valuable characterization parameter for evaluation of the polymer long term stabilities 462 – 4.2.5.5 and 4.2.3 for corrugated ducts and system components like inlets, outlets, valves and plugs made of PE or PP for minimum 20 minutes 462 – 4.2.5.6 for smooth PE ducts for minimum 40 minutes We want to point out that the test ducts are taken from standard production using PESTEC HDPE and PP standard materials not containing any special metal deactivator additives. Metal deactivator additives can increase short time OIT results without providing any long term property increase or advantage.


News 4 17000 m IP 3 M PP Duct for new HSL - High Speed Rail Station in Antwerp, Belgium 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.


News 3 New contract for biggest stay pipe size ever used on a Cable Stay Bridge 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 !!!

News 1 Polyolefin raw material price explosions since 6 month Following the 80% crude oil price increase during last 12 month the crude oil based ethylene as the basic material of polyolefin raw materials increased at least by 59% and HDPE pressure pipe grade raw material compound by 47% during the last 6 month. This global price increase in addition is caused by limited ethylen cracker capacities versus demands, as well in the situation that the big producers as e.g. BP, Shell, Fina and BASF had inadequate profits in the past and now focus on profit instead of quantity. These price increases of course strongly influence our product prices depending on the ratio of raw material versus roduction and transport costs of each product. Injection moulded parts are much less influenced by this price increase than e.g. the standard solid pressure pipes with dominant raw material factor. PESTEC watch closely this price trend and still keep offering competitive product prices in the future.
