Basic requirements for safe operation of pressure vessels Correct and reasonable operation and use of pressure vessels are important measures to ensure safe operation of the vessels. The basic requirements are smooth operation and prevention of overpressure, overtemperature and overloading. The safe and smooth operation of pressure vessels mainly refers to loading and unloading slowly and keeping the load relatively stable during operation. It depends on the operator's proficiency in the container's safe operating procedures and process flow, as well as the implementation of the operator's post responsibility system. Particular attention should be paid to the operating pressure and operating temperature of the container, as well as the loading, control and regulation of the liquefied gas and container. Timely discovery and accurate judgment of abnormal conditions during operation can often avoid the occurrence of major accidents or their further deterioration. In order to prevent overpressure, overtemperature and overloading of the container during operation, the following matters should be paid attention to: 1. Strictly implement safe operating procedures, ensure process operating conditions, and improve work responsibility during operation. 2. Hang safety operation signs on some key valves and operating devices, or install safety interlock devices to prevent misoperation. 3. When filling liquefied gas, strict measurement should be taken, and overfilling is strictly prohibited to prevent accidental heating. 4. Install reliable safety relief devices and overpressure alarm devices. 5. During intermittent operation and startup and shutdown in the operation process, the pressure and temperature should be as stable as possible to avoid unnecessary startup and shutdown.
