随着当前炼化的一体化、集约化,其石油化工生产装置规模越来越大,施工工期越来越紧,管道压力等级越来越高,加氢管道壁厚越来越厚,需进行焊后热处理的管道材质越来越多,其热处理技术显得越来越重要,而其热处理效果对装置生产的安全性、连续性也就显得尤其重要。
With the current integration and intensification of refining and petrochemicals, the scale of its petrochemical production plant is getting larger and larger, the construction period is getting tighter, the pipeline pressure level is getting higher and higher, and the wall thickness of the hydrogenation pipe is getting thicker and thicker and needs to be carried out Heat treatment after welding pipe material more and more, its heat treatment technology is more and more important, and its heat treatment effect on the device production safety, continuity is also particularly important.
