D. Pipe options
The standard 11-gauge pipe is the thickest on the market for enhanced durability. Southern Irrigation can help select the right pipe – poly-lined, galvanized steel, stainless steel, or aluminum – to manage corrosive water challenges. Corrosion of irrigation pipes can come from the oxygen contained in water, as well as from poor water quality from hydrogen sulphide, low PH, low alkalinity, wastewater as a source, or from adding crop chemicals to water.
The solution for growers who irrigated in corrosive water environments is Zimmatic polyethylene-lined pipe for center pivot irrigation systems, or “poly pipe”. Driven by customer-first innovation, this pipe has been developed with grower feedback to perform in even the most demanding environments. The poly flange is recessed which allows for positive steel flange contact. No gap between joint flanges results in improved strength and span consistency. This new manufacturing process increases friction between the poly liner and the steel pipeline, reducing lateral movement from temperature fluctuation.
Less stress, less corrosion = a longer leak-free lifespan.
