Measures to reduce stress concentration in the process of pressure vessel desi……

Pressure vessel is the key equipment in China’s petrochemical industry and industrial pharmaceutical industry. Because of its good storage function, it plays a positive role in promoting the production of pressure vessel. Therefore, safety, stability and other performance indicators are the key factors in the design and manufacturing process of pressure vessels, which have attracted extensive attention of designers and enterprises. Based on the characteristics of pressure vessels, the problem of stress concentration in the process of pressure vessel design and manufacturing is analyzed. Based on the existing process design technology, the process structure and design method are improved, and […]

Pressure source of pressure vessel

Pressure vessel pressure sources can be divided into two categories, one is the pressure generated or increased outside the vessel; the other is the pressure generated or increased inside the vessel. The pressure source that generates or increases pressure outside the vessel is generally a gas compressor or a steam boiler. Compressors increase gas pressure by mechanical means. Volume compressor by reducing the volume of gas, increase the gas density to increase the pressure of the gas, such as piston or screw compressor that belongs to this category, speed compressor by increasing the flow rate of gas, and its kinetic […]

Chemical pressure vessel corrosion effective control strategy research

With the continuous improvement of China’s industrialization level, pressure vessels are widely used in chemical production. Pressure, temperature, media and humidity and other factors can lead to pressure vessels in the use of the process of more serious corrosion problems. Because of the corrosion of a variety of situations, this paper from the strengthening of the pressure vessel corrosion phenomenon to start research, and targeted to different corrosion situations to put forward the corresponding protective measures.   Pressure vessel is a closed container, can carry a certain pressure, can be loaded with gas or liquid. In the use cycle of […]

What is a pressure vessel

What is a pressure vessel? Pressure vessel is a kind of airtight equipment which contains gas or liquid and bears a certain pressure. In order to implement scientific management and safety supervision more effectively, pressure vessels are divided into three categories according to working pressure, medium harmfulness and their role in production in China’s “safety supervision regulation for pressure vessels”. Different regulations are made on the design, manufacturing process, inspection items, contents and methods of each type of pressure vessel. The safety and quality licensing system for imported goods has been implemented for pressure vessels, and the goods without import […]

Four key points to improve the welding operation level of pressure vessel

For important structures such as boilers and pressure vessels, it is required that the joints be welded through safely. However, due to the limitation of structural size and shape, it is sometimes impossible to carry out double-sided welding. It is a difficult operation skill in manual arc welding. In vertical welding, due to the high temperature of the weld pool, under the action of gravity, the droplets formed by the melting of the electrode and the molten iron in the weld pool are easy to flow down to form weld bumps and undercut on both sides of the weld. When […]

General requirements of pharmaceutical industry for sanitary container design

In pharmaceutical water system, sanitary pressure vessels are widely used, such as softened water tank, purified water tank and water for injection tank, which are atmospheric pressure vessels or pressure vessels with sanitary requirements. The purpose of design and construction of sanitary container is to protect the product to the maximum extent. The contact surface of the product will not pollute the product during the process and it is easy to clean, reduce the dead angle of breeding chemical or microbial pollution, and provide convenience for cleaning, maintenance and inspection. The general requirements of pharmaceutical industry for the design of […]
