... is varied. IR drop constricted flow CP design INTRODUCTION If standard procedures (in recommended practices -for example DNV-RP-B401 ¹ ) are followed, it is generally possible to achieve a competently designed sacrificial CP system for an individual “protection object”, and for multiple...

... conclusion is that a CP design with only 2 to 4 anodes, appears to be inadequate. Once the Zn anodes are consumed, the waster sleeve and the steel areas can corrode quite rapidly as was encountered. The premature failure of waster sleeves is probably not a serious issue at the current time. However...

...DEH was for the first time installed on supermartensitic stainless steel (SMSS) pipelines around year 2000. At that time no special requirements for CP design with DEH existed. Based on testing, project specific requirement defining number of anodes and anode distance within the CTZ were given...
