1. The main testing of the pressure vessel

　　For pressure vessel equipment, the main testing includes external, internal, and overall testing. The first is external detection. The main testing items are: external surface shape, oxidation of metal materials, micro-cracks, air leakage, local temperature is too high, related accessories firmness and bolt connection stability and so on. The main testing method is daily inspection. If safety problems are found during the inspection, they should be shut down in time. The second is internal testing. In addition to all external testing items, the main items of internal testing should also be tested for corrosion and wear on the inner surface of the equipment. The main detection method is daily inspection. If safety problems are found during the inspection, they should be shut down in time. The second is internal testing. In addition to all external testing items, the main items of internal testing should also be tested for corrosion and wear on the inner surface of the equipment. For external inspection items, the main inspection method is naked eye or magnifying glass inspection. The internal structure inspection is mainly based on non-destructive inspection, such as radiographic inspection or ultrasonic inspection. Finally, the overall test, in addition to the above two items, should also check the pressure resistance of the pressure vessel. Among them, the main methods of pressure resistance are water pressure test and non-destructive testing of welds.

　　2. The influence of the application of non-ferrous materials on the inspection of the head

　　For non-ferrous metal materials, its impact on the inspection of the head is mainly due to incomplete standards. Although China has already formulated corresponding nonferrous metal material head inspection standards at this stage, with the maturity of related technologies at this stage, more and more nonferrous metal materials are applied to the actual head manufacturing. As a result, because many new materials lack corresponding standards, it is difficult to standardize their related testing work. This makes it difficult to ensure the safety and reliability of the pressure vessel.

　　3. Application requirements of nonferrous metal materials

　　1) Choose the appropriate design and manufacturing method. For the effective application of non-ferrous metal materials of the head equipment, choosing the appropriate design and manufacturing method is one of the most important measures. First of all, in the actual design and manufacturing process, the relevant staff should select the appropriate non-ferrous metal material according to the specific application of the head, and investigate its performance. Secondly, choose the appropriate design and manufacturing method, designers should try to choose the analytical design method to design and manufacture. At the same time, in the design and manufacturing process, the structural stress of the non-ferrous metal head is not sustained, the non-ferrous metal corrosion resistance is relatively poor and other related issues are fully considered, and on this basis, the most suitable process is selected for production.

　　2) Do testing carefully. At present, the relevant standards of non-ferrous metal materials are not perfect, so we should focus on the following tasks: First of all, the status of the head should be checked regularly, and the safety and reliability of the pressure vessel should be checked when it stops working. Secondly, the pressure resistance performance of non-ferrous metal pressure vessels should be regularly tested, and various indicators should be recorded in detail; finally, the status of non-ferrous metal pressure vessels under special circumstances should be tested, and corresponding security measures should be formulated at the same time. Only in this way can it be continuously improved Its safety and reliability.

　　In summary, in the context of the rapid development of modern industry, the requirements for pressure vessels in industrial production are also increasing. Only by taking corresponding measures and continuously researching the application of non-ferrous metals in pressure vessel processing equipment can we really play the positive role of non-ferrous metals in lifting pressure, high pressure resistance, high temperature resistance and corrosion resistance. Finally, the safe and efficient operation of industrial production is guaranteed.
