I. Introduction
Pressure vessel is an important equipment widely used in industrial production, energy utilization and scientific research. Because its internal medium usually has the characteristics of high temperature, high pressure, flammability and explosion, the safe operation of pressure vessels is of great significance to ensure the safety of personnel, the normal operation of equipment and environmental protection.
In order to ensure the safety and reliability of pressure vessels, regular inspection is essential. This paper will discuss the reasons for periodic inspection of pressure vessels from three aspects.
Second, preventive maintenance.
Periodic inspection is an important means of preventive maintenance of pressure vessels. Through regular inspection, potential safety hazards can be found and handled in time, and equipment failures or accidents can be prevented during operation. At the same time, preventive maintenance is also helpful to prolong the service life of pressure vessels, reduce maintenance costs and improve equipment operation efficiency.
Third, ensure safety performance.
The safety performance of pressure vessel is the key to its normal operation. Regular inspection can ensure the structural integrity, sealing performance and normal operation of accessories of pressure vessels. For example, by checking the container wall thickness, weld quality, corrosion, etc. , discover and repair potential defects in time, and prevent accidents such as leakage and explosion caused by equipment damage.
Function of pressure vessel
I. Important equipment in industrial production
Pressure vessel is one of the important equipment in industrial production, which is widely used in petroleum, chemical industry, pharmacy, food, metallurgy and other fields. In industrial production, many chemical reactions need to be carried out under certain pressure and temperature conditions, which are often beyond the normal pressure range, so it is necessary to use pressure vessels to carry these reaction conditions.
The use of pressure vessels not only improves production efficiency, but also makes industrial production safer and more reliable.
Second, important equipment to ensure life safety
Besides the application in industrial production, pressure vessels also play an important role in people's daily life. For example, liquefied petroleum gas tanks, oxygen cylinders and nitrogen cylinders are common pressure vessels in people's lives. The use of these containers provides people with convenient living conditions, such as liquefied petroleum gas can be used for cooking and heating, and oxygen can be used for medical treatment and first aid.
However, if these pressure vessels fail or leak, it will pose a threat to people's life safety. Therefore, the use and management of these containers must strictly abide by relevant laws and standards to ensure the safety of people's lives.
