Application of Stainless Steel Valve

Stainless steel valves have entered industrial applications due to their advantages of long service life and not easy to rust, and have become valve products that must be purchased in the pipeline field of various industries. Therefore, customers must require merchants to provide production and factory certificates of various stainless steel valves before purchasing stainless steel valves. Spectrometers can also be tested with spectrometers. Spectrometers are widely used due to their high precision and wide range of use, its application in the field of precious metals and stainless steel valve testing has also been rapid development in recent years, some 304, 316L valves are mainly dependent on the equipment testing, so that you can reduce the purchase of unqualified products.

Stainless steel valves are usually used in the working medium has a certain corrosive occasions, such as corrosive media, food, medicine, oil, liquid metal and radioactive media and other chemical products, in these areas any kind of valve materials, the ability to resist the corrosion of the working medium is relatively limited, and is affected by many factors. If the processing technology and heat treatment process used in the manufacturing process are appropriate, the corrosion resistance of this material is guaranteed. In the concentrated nitric acid medium with a concentration of> 98%, no matter what kind of heat treatment process is used, this steel does not have corrosion resistance. Therefore, according to the nature of the working medium to choose the ball valve, gate valve, globe valve and check valve and other valve materials, must also study the concentration of the medium, temperature and material heat treatment process and other factors on the corrosion resistance to choose a better steel such as 316L, 904 or titanium valve.

With the continuous development of petrochemical industry technology and scale, the requirements for petrochemical stainless steel valves are getting higher and higher. In addition to continuing to improve the quality of regular valves such as J41W stainless steel stop valve and Z41W stainless steel gate valve, etc., especially the demand for Q41F stainless steel ball valve for corrosive materials is increasing, such as ethylene cracking device, polyethylene device and polypropylene device in ethylene production, PTA device (refined terephthalic acid), polyester device and polyester spinning device in chemical fiber production, therefore, efforts should be made to develop corrosion-resistant technology. 316L stainless steel valves have excellent characteristics such as corrosion resistance, high strength, portability and long service life.

Society in the progress of the industry is increasing, for the use of stainless steel valve products industry is also increasing, the new industry new products and will slowly replace the cast iron valve, which brings new opportunities for the stainless steel valve industry market development prospects are good.
