This need has led to the development of hyper-duplex stainless steels., 01 Mar 2015 00:00:00 GMTHow caustic stress leads to failures of incinerator caustic spray nozzlesFrequent failures of the waste spray nozzles in incinerators result in accelerated degradation of the refractory lining, requiring unscheduled shutdowns for repairs. A study was carried out to identify the factors that contributed to the nozzle failure and to prevent the reoccurrence of similar failures in the future., 01 Mar 2015 00:00:00 GMTHP Innovations, 01 Mar 2015 00:00:00 GMT
