The reliability of bleach plant equipment has been considerably improved over the last decade thanks to better process control and introduction of advanced alloys for corrosive service conditions. The paper briefly describes modern material selection practice for bleach plant applications. Nevertheless, failures of stainless alloy parts still occur, robbing the industry of valuable production time. Specifying higher alloy composition for a given part is often not sufficient in order to improve its performance, if appropriate changes and safeguards are not included into the purchase orders or repair contracts. The users of equipment must be aware of the necessary changes and the need to transfer the important information from the new equipment supplier to the local contractor or the repair shop.
