湖南衡阳钢管(集团)有限公司(简称:华菱衡钢)生产的13Cr系列耐腐蚀不锈钢管,已通过实验评定。随着世界石油工业的发展,深层含二氧化碳(CO2)油气层的开采条件越来越趋苛刻,油井中CO2溶解于水后形成的碳酸对钢材腐蚀性极强,容易引起设备损坏和油井的报废,造成了巨大的经济损失。增强油套管抗CO2腐蚀性,13Cr耐腐蚀合金是一种经济、有效的选择。但由于13Cr材质合金含量高,生产难度大,
Hunan Hengyang Steel Pipe (Group) Co., Ltd. (referred to as: Valin Heng Steel) production of 13Cr series corrosion-resistant stainless steel pipe, has passed the assessment of the experiment. With the development of the world petroleum industry, the mining conditions of deep CO2 gas reservoirs have become more and more harsh. The carbon dioxide formed in the oil wells after being dissolved in water is highly corrosive to steel, which can easily cause equipment damage and oil well scrap , Resulting in huge economic losses. Enhanced oil casing CO2 corrosion resistance, 13Cr corrosion-resistant alloy is an economical and effective choice. However, due to high content of 13Cr alloy material, production difficult,
