Pipeline,as a reliable and economical infrastructure,plays a very important role in many industries like petrol,chemical and nuclear industries.Corrosion is the major indication of pipeline failure.Both internal and external corrosions are very effective in damaging pipelines.Thus,pipeline corrosion becomes a severe danger of the running pipeline system nowadays,which can lead to transported matter escapes,conduits ruptures and reduced lifetimes and all that.The disastrous consequences brought by these accidents are severe,such as economic loss and casualty as well as environment pollution.Therefore,controlling of pipeline corrosion is very vital.To control pipeline corrosion successfully and prolong pipeline life effectively,this article separately introduces corrosion phenomena and corrosion mechanism in detail.After this,the prediction methods were presented to reduce the loss caused by corrosion.Besides,the inspection techniques can analyze the reasons of the corrosion and also be applied to estimate and evaluate the corrosion control measures outcome,which make great contribution to future corrosion control.This paper proposes effective countermeasures concerning the corrosion control based on the corrosion mechanism,introduces corrosion control techniques both internally and externally.
