Analysis of the Causes of Corrosion and Cracking of the Injection Oil line and the Application of Repair Tooling
With the long-term operation of chemical plants,there are leakage problems such as wall thickness thinning,corrosion perforation,and stress cracking in equipment and pipelines.Based on years of experience in plugging leaks under pressure,our unit makes special tooling for the sealing and welding process of flammable and explosive pipelines,and carries out nitrogen-filled protection welding in the whole process,and successfully eliminates the hidden leakage danger by using this technology under the condition of normal operation of a compressed 10-K-201 compressor.This paper focuses on the analysis of the causes of cracks,and expounds the development and application of nitrogen charging protection tooling in the case of combustible gas leakage,which can effectively ensure the safety of personnel and the occurrence of secondary accidents,and avoid the emergency shutdown of the device.
