Pipeline Choices
Changing water conditions require specific pipeline choices
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. Our application experts work with Valley Dealers to identify the best solution for your needs. Choosing the correct Valley product will provide the best long-term value.
