1. Types of submarine pipelines
According to the material composition, the submarine pipelines are generally divided into carbon steel pipes and corrosion-resistant alloy composite pipes. For the exploitation of highly corrosive oil and gas fields, traditional single anti-corrosion technologies and materials such as adding corrosion inhibitors, using plastic inner coatings, and corrosion-resistant alloys are difficult to balance in terms of reliability of corrosion resistance and economic indicators; it is difficult to meet the needs of the development of oil and gas fields. To reduce the production cost and prolong the service life of the pipeline, the use of a bimetal composite pipe is one of the relatively safe and economical ways to solve the corrosion in high H2S or CO2 oil and gas fields.
