Reliability consistent mitigation criteria for corrosion defects on natural gas transmission pipelines

Co2 Corrosion on Natural Gas Compressors: Criteria and Guidelines

Liquid water and CO2 can easily lead to carbon steel corrosion, especially at high pressures. Corrosion can happen either during normal running or during pressurized standstill conditions. The present paper describes three real cases of gas lift compressors operating in offshore platforms that suffered internal damage due to the formation of carbonic acid and unfavorable process conditions. The...

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...

EMAT-Based Inspection of Natural Gas Pipelines for Stress Corrosion Cracks

Reliability Analysis of Aged Natural Gas Pipelines Based on Utility Theory

Article history: Received: 27.08.2014. Received in revised form: 08.12.2014. Accepted: 11.12.2014. Pipelines are of major importance for transport of natural gas, but a lot of the current in-service pipelines are in wear-out phase. Safe and reliable operations of these pipelines are related to economic development and social stability. It is of great importance and practical significance to stu...
