61747 - Research and Application of Safety Valves Inspection Method Based on Failure and Risk Big Data 

Inspection interval of safety valve is generally at least once a year specified by the Safety Technical Supervision Regulations for Safety Valves (TSG ZF001-2006) in China, while the maintenance interval of production equipment in oil refining and chemical enterprises is usually 3-5 years. There is a prominent problem that inspection interval and maintenance interval is not consistent. This paper reveals the main failure modes，opening rate as well as maintenance replacement condition by analyzing the operation condition of 24720 safety valves of 145 typical units in oil refining and chemical industry. Moreover, the data of 44692 safety valves carried out in RBI engineering applications in the past eight years are statistically analyzed to grasp the risk distribution and risk level of safety valves. Based on the big data of safety valve failure and risk, this paper proposes the safety valve inspection method to solve the contradiction between inspection interval and maintenance interval, which further realizes the legal compliance and long-term safe operation of production units in oil refining and chemical enterprises. The advantages and limitations of this method are summarized by sharing the engineering application cases of "Safety valve inspection based on big data of failure and risk in a petrochemical company ".
