摘要
随着对油气田的深入开发,发现管线面临的腐蚀环境越来越恶劣,特别在一些高含H 2S/CO 2油气田,管线腐蚀问题十分严重。普通碳钢难以满足要求,耐蚀合金价格又昂贵,而双金属复合管能有效地解决上述问题,其防腐蚀效果显著,双金属复合管具有广泛的应用前景。
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.
