Best Abrasion Resistant Piping Solutions
Steel piping systems are commonly employed in coal-fired power plants for a number of uses, including the transport of coal ash slurry to surrounding settling ponds, the transfer of calcareous slurry to absorbing spray towers to extract sulfur dioxide (SO2) and hydrogen chloride (HCl) from flue gases, and the processing of calcium sulfate by-product from the flue gas desulfurization cycle. Moreover, as such abrasive, caustic slurries are transferred though a steel pipe, the result may be destructive on the inner surface. In these transport systems abrasive wear is created when hard particles are pressed against or slid along the pipe wall. The material loss occurs from the rough, sharp angular edges that create a cutting or shearing motion on the pipe surface, which in more serious situations may contribute to pipe leakage and even collapse, or severe repairs and downtime for pipe replacement The mild steel tubing for such abrasive applications is not robust enough to hold up to the
