National Corrugated Steel Pipe Association recognizes TRENCHCOAT™ Polymer Film from Dow
Article Type: New materials and equipment From: Anti-Corrosion Methods and Materials, Volume 60, Issue 5
NCSPA study shows polymer film provides pipelines with “the best performing” corrosion protection.
TRENCHCOAT™ Protective Film, from The Dow Chemical Company has been cited in a study by the National Corrugated Steel Pipe Association (NCSPA) as the best performing polymer coating product for protecting corrugated steel pipe (CSP). The polymer, which can be applied to corrugated steel pipes and structural steel plates, is designed as a two-layer adhesive film. It offers corrosion and abrasion protection, and is laminated on the inside and outside of galvanized steel for storm drain and culvert system applications.
TRENCHCOAT Protective Film provides long-term durability, structural integrity and hydraulic capacity. It was initially developed in 1974 to combine the lightweight and high strength characteristics of galvanized CSP with the chemical resistance and toughness of polymer technology. TRENCHCOAT resists delamination and bonds physically and chemically to galvanized steel. The polymer film offering has also been validated in other studies conducted by the NCSPA, fabricators and state departments of transportation.
“With the proven performance of TRENCHCOAT Protective Films over the last 40 years, as cited in the NCSPA study, we are excited for the opportunity to push this technology to the next level,” Mike Mounts, Performance Plastics Development Leader at Dow said. “The polymer film offers our customers a high-performance quality material that can withstand extreme environmental conditions, helping to extend the pipe’s lifetime and support the Company’s sustainability initiatives.”
Over the past several decades, North America has experienced progressively severe environmental conditions – harsh weather changes, the increased use of salt on roadways, industrial pollution and acid rain. These issues not only affect surface water conditions, but also piping systems, which may result in critical corrosion damage. The average 50 year lifespan of culvert systems may then be compromised when exposed to extreme environmental conditions for an extended period of time. Based on laboratory tests conducted by NCSPA and Dow, it was found that the barrier coating exhibited uniform durability within a variety of environmental ranges, when compared to aluminized and galvanized materials. The protective film serves as an economical option that can help decrease maintenance costs and extend the timeframe before pipe replacement.
