Pressure vessels are widely used in many fields such as chemical industry, petroleum, energy, etc., and it is crucial to ensure their long-term safe operation.

In terms of design, accurate calculations should be made based on accurate process parameters. According to the operating pressure, temperature, medium and other factors of the container, the structural form, wall thickness and other parameters of the container should be reasonably determined, and the relevant design standards should be strictly followed. During the manufacturing process, the raw materials are strictly inspected to ensure that the quality of the materials meets the requirements. Welding work should be performed by qualified welders in accordance with standard welding process regulations, and non-destructive testing should be performed on the welding joints, such as radiographic testing and ultrasonic testing, to ensure the welding quality and prevent defects such as cracks and incomplete penetration.

During installation, the installation instructions must be followed. Ensure that the foundation of the container is firm and stable, and that the connection with the connecting pipe is accurate to avoid additional stress caused by improper installation. During the commissioning stage, slowly increase the pressure and temperature, and conduct a comprehensive inspection, including sealing performance, whether the instrument display is normal, etc., to ensure the safety of the initial operation of the container.

During operation, regular inspections and maintenance should be carried out. Daily inspections should check whether the appearance of the container is deformed or leaking, and whether the pressure, temperature and other instruments are working properly. Conduct internal and external inspections regularly to evaluate the wall thickness, corrosion, and effectiveness of safety accessories of the container. At the same time, keep maintenance records to trace the operating status of the container.

Safety accessories such as safety valves and bursting discs are the last line of defense for pressure vessels. Check the safety valve regularly to ensure that its starting pressure is accurate and the return seat is good. The bursting disc should be replaced regularly to ensure that it can rupture and release pressure in time when overpressure occurs.

Only by strictly requiring in design and manufacturing, installation and commissioning, operation management, and safety accessories can the long-term safe operation of pressure vessels be ensured, thereby ensuring production safety and the safety of life and property of personnel.
