Pressure vessels can be divided into metal and non-metallic
According to the production material, pressure vessels can be divided into metal pressure vessels and non-metallic pressure vessels. However, with the development of the industry, the most widely used pressure vessels are still metal.
Metal pressure vessels occupy most of the market
——The scale of China's pressure vessel market exceeded 80 billion yuan
According to the market share of metal pressure vessels in China's pressure vessel market and the operating income of the metal pressure vessel industry, the market size of China's metal pressure vessels and non-metallic pressure vessels can be derived, and the market size of China's pressure vessel industry will exceed 80 billion yuan in 2020.
——The competition in the metal pressure vessel market is fierce
In 2020, in China's pressure vessel industry, metal pressure vessel products will dominate the market, and most of the pressure vessel market will be contributed by metal pressure vessel products, and the field of metal pressure vessels currently has great competition.
The market for non-metallic pressure vessels may expand in the future
——With the breakthrough of technology, non-metallic pressure vessels may replace some metal pressure vessels
Because the marketization and industrialization of non-metallic pressure vessels are far from the difference between metal pressure vessels, there are fewer non-metallic pressure vessel enterprises, and their ** is relatively high, so it also leads to the demand in the market to a certain extent in the bottleneck period. However, with the development of China's pressure vessel industry and technological breakthroughs, the number of categories of new materials available for pressure vessels will increase, and the further marketization and industrialization of new materials may lead to the possibility of narrowing China's metal pressure vessel market.
——In the future, the competition in the non-metallic pressure vessel market will intensify
In fact, the application scenarios of non-metallic pressure vessels are wider than those of metals, but they are limited by technical requirements; With the breakthrough of the technical bottleneck of the use of new materials in pressure vessels, the market demand for non-metallic pressure vessels will gradually increase, and the competition will become more and more intense.

It's okay to do design, but the best is the pressure vessel inspection industry.

Very good.. It is needed to make chemicals, and it is also used to make cosmetics.

Hello, objectively speaking, the current domestic pressure vessel industry is not too prosperous. To put it bigger, petrochemical and pressure vessel manufacturing enterprises are not too prosperous. Therefore, the future of the pressure vessel industry is not too clear.
However, it is certain that this industry is not a high-income industry, but the professional knowledge and knowledge of container regulations, standards and theoretical knowledge are very high, so the threshold is still relatively high. A certain level of theoretical and technical proficiency is required. If you don't like this too much, it's not too recommended to do it.
The nozzle of the pressure vessel (i.e. the flange connection) clearly stipulates that the flange refers to HG T20592, and the pipe has GB T8163, GB6479, GB9948, GB5310 and stainless steel GB T14976 and GB13296 >>>More
Relief valve. safety valve
Valves used to prevent damage to equipment or pipelines such as boilers and pressure vessels due to overpressure. When the fluid pressure in the protected body reaches a specified value slightly higher than the normal working pressure (i.e., the valve opening pressure), the safety valve will automatically open and discharge part of the fluid, so that the pressure will drop. When the pressure drops to a certain value slightly below the normal operating pressure (i.e., the valve return pressure), the safety valve automatically closes, stopping the discharge of fluid and maintaining a seal. >>>More
Broadly speaking, pressure vessels generally refer to all closed vessels that bear a certain pressure, including fixed pressure vessels, mobile pressure vessels, gas cylinders, oxygen chambers, etc. So strictly speaking, gas cylinders belong to a type of pressure vessel. >>>More
The standards of various countries are not the same, and they are often not interoperable, and they are generally used for pressure vessels in which country, and they are controlled according to the standards of which country, and they cannot be simply judged whether they are good or not. For example, no matter how good the design of foreign pressure vessels is, they are designed according to foreign standards, and if they are used in China, they must meet Chinese standards. Then it makes no difference.
Fill in the "Design Power of Attorney", the drawings belong to the external documents, should fill in the "Design Document Review Record", and then prepare the "Main Pressure Element Process Flow Card", "General Pressure Component Process Card", "Pressure Test Process Card", "Leakage Test Process Card", "Heat Treatment Process Card", "Welding Process Specification" and other process documents, and then fill in the corresponding records in real time in the manufacturing process**, these are specified in detail in the "Quality Assurance Manual", and all kinds of ** are also in a controlled state, There is a certain format, if the evidence is obtained, "quality assurance manual", "procedure documents", "process code", "work instructions", "post responsibility system" and various forms and cards must be made first, and then implemented according to this provision. You can follow the requirements of Circular No. 22 and No. 194 and TSG Z0005-2007 and TSG Z0004-2007. Your question is too much to complete.
