Lindsay Zimmatic poly pipe for corrosive water

According to Lindsay, polyethylene-lined pipe, or “poly pipe,” is the leading solution for growers who irrigate in corrosive water environments. The company says it engineered its new Zimmatic poly pipe to “consistently deliver the highest level of performance and structural integrity in the most extreme conditions”.

Poly pipe offerings in the market rely on poly flanges for structural integrity, but poly flanges create a gap between the steel flanges at the joint and can compress over time, resulting in leaks, says Lindsay.

Recessed poly flange

The new Zimmatic poly pipe features a recessed poly flange that allows for positive steel flange contact and eliminates the gap between flanges at joints, resulting in improved strength and span consistency. It is the same span joint design used for existing Zimmatic galvanized pipe, but with the added protection of the poly liner through the span pipe to provide an unmatched level of quality and rigidity.

To address the poly expansion and contraction challenges that cause the poly liner to move within the pipe, potentially leading to cracks and leaks, Lindsay introduced 2 additional new design innovations. First, the liner is forced through the steel flange openings during formation for positive flange retention.

Pressure reversion manufacturing process

Further, a proprietary new pressure reversion manufacturing process increases the friction between the poly liner and the steel pipeline to further reduce any lateral movement caused by temperature fluctuations inside the pipe. This process also reduces the lateral stress on the pipe outlets, which can cause leaking.

To produce this new solution, Lindsay is investing in a new facility at the company’s primary pivot manufacturing plant in Lindsay, Neb.

Custom-designed to meet individual grower’s needs

Regarding the price of the poly pipe, Jenna Zeorian, Senior Marketing Specialist at Lindsay, says: “Because every field is different and every grower’s needs are unique, Zimmatic dealers help customers configure the best irrigation solution for their operation. As a result, every system we deliver is custom-designed to meet the individual grower’s needs. Lindsay has made a significant investment in this product line, while still offering tremendous value to growers. We’re able to keep the pricing on par with other solutions on the market. This means we can now better address a market need while maintaining competitive pricing.”
