Corrosion testing of experimental steels for oilfield pipelines

Mechanical Anisotropy in Steels for Pipelines

There has been a huge expansion in the laying of pipelines for the transmission of fossil fuels over large distances and in dire environments. One particular problem associated with the steels used to fabricate the pipes is that of the anisotropy of mechanical properties, especially the toughness. This review represents an attempt to critically assess the steels and the orientation dependence o...

Cathodic Corrosion Protection of earthburried Pipelines

Inhibition of Pipelines Corrosion Using Natural Extracts

The present work is aimed at examining carbon steel oil pipelines corrosion using three natural extracts (Eruca Sativa, Rosell and Mango peels) that are used as inhibitors of different concentrations ranging from 0.05-0.1wt. %. Two sulphur compounds are used as corrosion mediums. Weight loss method was used for measuring the corrosion rate of the carbon steel specimens immersed in technical whi...

Hydrogen Induced Stress Corrosion of Prestressing Steels - Introducing a New Testing Method

The causes for the susceptibility of prestressing steels to hydrogen induced stress corrosion and the failure mechanisms occurring could be researched in depth. In contrast to this an exact testing method on the evidence of the prestressing steel sensitivity valid for all steel types does not exist. This has caused not only prejudices against prestressed buildings but has also led to additional...

Graphene nanocomposite coatings for protecting low-alloy steels from corrosion

facturing methods. Graphene nanocomposite coatings for protecting lowalloy steels from corrosion A ceramic engineer or scientist unfortunately must admit that there is an unwelcome member of the family among us—iron oxide, or rust. This unpleasant family member is disruptive at best. More often it is destructive, nearly impossible to control, and a consumer of resources that are devoted to it i...
