Polymer Coated CSP Provides Superior Service Life to Most Pipe

Have a tough drainage application where pipe service life is a concern? Corrugated Steel Pipe (CSP) made of Polymer Coated Steel is the answer. Polymer Coated CSP has been proven to provide superior service life of up to 100 years and can be used in applications where soils and effluent have PH from 3 to 12 and any resistivity >100 This tough and durable polymer film, called TRENCHCOAT™ Protective Film and developed by The Dow Chemical Company, is bonded over galvanized steel sheet prior to the corrugation and pipe forming processes, providing a product that will survive both the elements and the installation in the most challenging environments.

Polymer Coated CSP is a proven product with hundreds of successful installations over 36 years. It has been subjected to chemical resistance tests under ASTM A543 and A742 and has proven its chemical and corrosion resistance capability. Polymer Coated CSP is also proven in landfill applications such as methane recovery, combining its corrosion resistance with the flexible character and positive connections of corrugated steel pipe to stand up under heavy settling loads.

When the project calls for a pipe product that is light, strong, supremely durable, and corrosion resistant, Polymer Corrugated Steel Pipe is the answer. The members of the National Corrugated Steel Pipe Association can help with your product selection and specification needs.

On March 18, 2010 the latest extension of SAFETEA-LU was signed into law and will run through December 31, 2010. The funding in this latest extension will give federal highway programs a total of $42 billion for FY 2010, restore $8.7 billion in contract authority that was rescinded in FY 2009, and transfer $19.5 billion into the Highway Trust Fund.

Overall, this should translate to a spending increase of approximately 20% over 2009 levels. While this increase seemingly shows a glimmer of hope for highway spending over the next several years, some still feel that long-term highway legislation and funding mechanisms are a still a long ways off. Former U.S. DOT Transportation Secretary James Burnley IV, told D.C. Velocity that it may be as late as 2013 before a new long-term legislation is in place. “I started saying a year ago that we were facing four years of short-term extensions of existing [federal funding] programs, and I’m sorry to say that this is a prediction that I believe will come true,” he told the magazine. If this holds true, the transportation construction industry could be seeing a few more lean years ahead.
