AWWA C222 Standard: Polyurethane Coatings & Linings for Steel Water Pipes & Fittings
To guide manufacturers, operators, contractors, and customers in purchasing and using protective coatings and linings in the water industry, the American Water Works Association (AWWA) has established a set of standards outlining the minimum requirements for certain products. Complying with AWWA standards is not required by law; however, choosing products that meet the minimum requirements outlined in the standards is the best way to ensure they will stand up to the rigorous and often harsh conditions of the industry.
Are you looking for proactive coating and lining solutions for steel water pipes or fittings? An AWWA C222-compliant polyurethane product may be the best option.
What Is the AWWA C222 Standard?
The AWWA C222 Standard for Polyurethane Coatings and Linings for Steel Water Pipe and Fittings describes the minimum requirements for protective polyurethane coatings or linings applied to steel pipes and fittings.
The purpose of AWWA C222 is to help water industry professionals and consumers identify what makes an effective polyurethane coating or lining, making it easier than ever to identify the best products to use. It addresses both shop- and field-applied polyurethane coating and lining products.
The Basics of AWWA C222: What Is Covered?
The standard outlines a variety of aspects that relate to polyurethane coatings, including the material itself, how the surface of the steel water pipe or fitting should be prepared, what tests the material should pass, and how it should be handled, transported, and packaged. It details the standards for measuring impact resistance, flexibility, water absorption, and more and sets minimum requirements in each category.
How to Comply with AWWA C222?
Polyurethane coatings are used as a barrier between the steel water pipe or fitting and the surrounding environment, acting as a durable, resilient, chemical resistant, anti-corrosive shield that lasts for years and extends the service life of the steel, under normal working conditions. These products have several applications, from protecting pipes and joints to connections and fittings, both underwater and underground, and they aggressively adhere to the steel substrate to provide long-term protection.
Using AWWA C222-compliant polyurethane coating and lining products is voluntary, and the standard does not supersede any legal or governmental regulations. However, it acts as a purchasing guide for polyurethane coatings and linings to ensure the product meets expected performance standards.
We recommend sticking with polyurethane coating and lining products that meet the requirements of this standard. However, remember to defer to NSF/ANSI/CAN 61: Drinking Water System Components certification for products used to transport or contain potable water.
