双金属复合管试压封头焊接技术
Pressure End Socket Welding Technology for Bimetal Composite Pipe

在我国油气田地面建设工程中，原料油气中所含的CL？、H₂S、CO₂等腐蚀介质对普通碳钢或低合金钢造成很大的破坏，并发生过多次的爆管泄漏事故。为此，综合了不锈钢管的耐腐蚀能力和碳素钢管的承压能力并且具有良好的经济使用性的双金属复合管在油气田开发中逐步得到了广泛的应用。
In the fields of China oil and gas, corrosion media such as CL？, H₂S and CO₂ contained in the raw oil and gas have caused great damage to ordinary carbon steel or low-alloy steel, and there have been caused many pipe blasting and leakage accidents. Therefore, the bimetal composite pipe, which combines the corrosion resistance of stainless steel pipe with the pressure bearing capacity of carbon steel pipe and has good economic utility, has been widely used in the development of oil and gas fields.
