Corrosive Water Solutions
Pipeline solutions for corrosive water applications
In certain areas, water that was once known to be clean and non-corrosive is increasingly becoming more corrosive. Some producers are using less desirable sources – waste water, process water and corrosive water. Other producers are adding crop protection chemicals or soil amendment products. Under these conditions, corrosion of standard galvanized steel can occur at varying rates.All materials except PolySpan® are susceptible to corrosion failure. With time, depending upon the water quality, corrosion failure can occur in a few year or it may take several decades. The only reliable method for determining water quality as it relates to the pipeline is to have your Valley dealer obtain a water sample for analysis and provide you with an estimate of your pipeline line. Choosing the correct Valley product will provide the best long-term value.
Based on continued studies and tests of our products, listed below are the Valley choices.
