Key Benefits of Teflon™ Industrial Coatings
• Corrosion resistance
• Chemical resistance
• Low coefficient of friction
• T-bolts for ductile iron water pipe - anti-galling with corrosion resistance
• Grates - releases build up of sediment material that occurs during the waste process
• Pumps - minor chemical resistance and low COF
The US commercial water and sewer industry includes approximately 5,000 companies who generate an estimated $9 billion in annual revenue. Their primary focus is companies that provide equipment and services to communities, chemical facilities, and food manufacturers with water treatment issues. The commercial segment of the water treatment industry is relatively small compared to the $55 billion spent annually on water and sewage services by regional and local governments. With continued population growth and more stringent drinking water standards, the EPA estimates the industry will be spending some $280 billion to upgrade facilities during the next 20 years.
The market is concentrated, with the 50 largest companies (e.g., American Water Works, California Water, Aqua America, etc.) accounting for nearly 65 percent of overall revenue. The industry is expected to continue to consolidate, as larger companies find it easier to gain capital funding for expensive maintenance projects.
Critical Coating Issues
The primary issue is corrosion resistance with enough slip to prevent galling. Where there is a high level of water corrosion, resistance becomes an issue. With thousand of pipe connection points - and replacement of those pipes inevitable over the next 20 years - Teflon™ coatings are being used on many T-bolt connector fasteners. Movement of thousands and thousands of gallons of water also causes stress to large pumps. Pump replacement and repair can also drive increases in Teflon™ coatings for this industry.
Coating demand for parts is primarily driven by new construction and maintenance of pumps and corroding infrastructure projects. Maintenance and capital costs are often higher than operating costs and pipe maintenance is especially expensive as pipes are usually located under roadways. New facility construction peaked in 2005 and 2006 with significant decreases in 2010, but the EPA projects that by 2016 more than half of the country’s sewer pipes will be in poor, very poor, or broken condition.
