Analysis on the application fields of stainless steel valves
Release Time:2020-08-28  Browse: times
    Stainless steel valves have entered industrial applications due to their outstanding advantages such as long service life, resistance to rust, and environmental protection. They have become the must-purchased valve products in the pipeline field of various industries. Therefore, customers must ask the merchants to provide various products before purchasing stainless steel valves. The production and delivery certificates of stainless steel valves can also be tested with a spectrometer. The spectrometer is widely used due to its high accuracy and wide range of use. Its application in the detection of precious metals and stainless steel valves has also been rapidly developed 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 occasions where the working medium is corrosive, such as corrosive medium, food, medicine, oil, liquid metal and radioactive medium and other chemical products. In these fields, any valve material is resistant to corrosion by the working medium. Capabilities are relatively limited and are affected by many factors. If the processing technology and heat treatment technology used in the manufacturing process are proper, the corrosion resistance of this material can be guaranteed. As for the concentrated nitric acid medium with a concentration of >98%, no matter what heat treatment process is used, this steel does not have corrosion resistance. Therefore, when selecting valve materials such as ball valves, gate valves, stop valves and check valves according to the nature of the working medium, it is necessary to study the influence of the concentration, temperature and heat treatment process of the material on the corrosion resistance of various factors to choose a better Good steel materials such as 316L, 904 or titanium valves.

    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 conventional valves such as J41W stainless steel globe valves, Z41W stainless steel gate valves, etc., especially for corrosive materials Q41F stainless steel The demand for ball valves is increasing, such as ethylene cracking unit, polyethylene unit and polypropylene unit in ethylene production, PTA unit (purified terephthalic acid), polyester unit and polyester spinning unit in chemical fiber production, etc. Efforts should be made to develop corrosion-resistant technology. 316L stainless steel valves have excellent characteristics such as corrosion resistance, high strength, light weight, and long service life.

    The society is progressing. The number of industries is increasing, and the number of industries that can use stainless steel valve products is also increasing. New industries and new products will gradually replace cast iron valves. This brings new opportunities for the stainless steel valve industry and has a good market development prospect.
