Fly ash, a byproduct of coal combustion in power plants, must be controlled from the point of generation to processing, storage and disposal sites. Fly ash lines play a crucial role in managing this material efficiently and safely. Fly ash is often transported in pneumatic conveyance systems that use air pressure to move the ash through the system. Fly ash is abrasive and moves at considerable speed, which generates significant wear and tear on pipes and components. Materials engineered for this purpose and regular maintenance are essential to maintain these crucial systems. Ultra Tech 600 Extended Life Elbows (XLE) are cast with high-manganese content that work-hardens as it absorbs material impact. Ultra 600 induction-hardened pipe is heat-treated to create an inner pipe wall of 600 BHN that excels in pneumatic systems.
