Stainless Steel Free Systems and Custom-Alloy Solutions

We offer plastic piping systems which are specifically designed for WWTP applications requiring highest corrosion resistance. These systems – apart from their fastening hardware – are completely free of stainless steel, therefore ensuring long and maintenance-free operation under the most demanding conditions. Our AirRex® header system provides a viable technical solution for WWTPs processing highly corrosive wastewater at high temperatures. AirRex® piping systems are designed to permit linear thermal expansion and provide reliable service at temperatures up to 120°C (248°F).
