延迟焦化装置加热炉铬钼合金钢管道焊接技术分析OA

Delayed coking unit can remove petroleum coke and conforms to the working concept of energy saving and environmental protection,so delayed coking unit is widely used in petrochemical industry.Because the heating furnace of delayed coking unit is in the environment of high temperature and high pressure,coupled with the influence of material characteristics,cracks and other problems often occur in chromium-molybdenum alloy steel pipe,which affect the stability of equipment operation.Therefore,it is necessary to strengthen the research on the welding technology of chromium-molybdenum alloy steel pipe in the reheating furnace of delayed coking unit,and put forward corresponding improvement measures in view of the existing problems,which can be used as a reference for practical work.
