Endorsement notice The text of ISO 15589-2:2012 has been approved by CEN as EN ISO 15589-2:2014 without any modification. IntroductionThe technical revision of this part of ISO 15589 has been carr
33、ied out in order to accommodate the needs of industry and to move this International Standard to a higher level of service within the petroleum, petrochemical and natural gas industry.Pipeline cathodic protection is achieved by the supply of sufficient direct current to the external pipe surface, so
34、 that the steel-to-electrolyte potential is lowered on all the surface to values at which external corrosion is reduced to an insignificant rate.Cathodic protection is normally used in combination with a suitable protective coating system to protect the external surfaces of steel pipelines from corr
35、osion.Users of this part of ISO 15589 should be aware that further or differing requirements may be needed for individual applications. This part of ISO 15589 is not intended to prevent alternative equipment or engineering solutions from being used for individual applications. This may be particular
36、ly applicable where there is innovative or developing technology. Where an alternative is offered, it is intended that any variations from this part of ISO 15589 be identified and documented.This part of ISO 15589 can also be used for offshore pipelines outside the petroleum, petrochemical and natur
