Application Prospect of Stainless Steel Valves

Stainless steel valves are used for the industrial application because of their outstanding advantages such as long service life, not easy to rust, and environmental protection. They have become the valve products that must be purchased by relative industries. Therefore, customers should ask the merchants to provide the production and factory certificates of the stainless steel valve before purchasing, and can also require them to use spectrometers for testing. Spectrometers are widely used due to their high precision and a wide range of applications. Some 304 and 316L valves mainly rely on these devices for testing, which can reduce the purchase of unqualified valves.

Stainless steel valves are usually used under the condition that the working medium is corrosive. They can be used to control the flow of media, such as corrosive media, oil, liquid metal, radioactive media. Any valve material has relatively limited resistance to the corrosion of the working medium and is affected by many factors. If the processing technology and heat treatment properly used in the manufacturing process, the corrosion resistance of the valve material can be guaranteed.

If the stainless steel is applied to the concentrated nitric acid with the concentration higher than 98%, it has no corrosion resistance no matter what kind of heat treatment process is adopted. Therefore, when valve materials are selected according to the properties of the working medium, it is necessary to study the influence of media concentration and temperature, and heat treatment process of materials on corrosion resistance.

With the continuous development of petrochemical industry technology and the increasing scale of the industry, the requirements of the petrochemical industry for stainless steel valves are getting higher and higher. Besides improving the quality of valves, efforts should also be made to develop corrosion-resistant technologies. 316L stainless steel valves have excellent characteristics, namely corrosion resistance, high strength, portability and long service life.

With the development of society, industries is increasing, and the industries that can use stainless steel valves are also growing, which brings new opportunities for the stainless steel valve industry.
