| Abstract: | With the development of oil and gas fields,the corrosion of pipelines is getting worse and worse,especially in some oil and gas fields with high content of H 2S/CO 2.Ordinary carbon steel is difficult to meet the requirements,while the corrosion-resistant alloy is expensive.CRA clad or lined steel pipe can effectively solve the above problems,and its anti-corrosion effect is remarkable.So CRA clad or lined steel pipe has a wide range of application fields and prospects. |
