Brief Analysis Of The Application Fields Of Stainless Steel Valves
Stainless Globe Valve has entered industrial applications due to its long service life, not easy to rust, green and environmentally friendly advantages, and has become a valve product that must be purchased in the pipeline field of various industries. Therefore, customers must ask merchants to provide various stainless steel valves with production and factory certificates before purchasing stainless steel valves. They can also be tested with spectrometers. Spectrometers are widely used due to their high precision and wide range of use. Their application in the field of precious metal and stainless steel valve detection has also developed rapidly in recent years. Some 304 and 316L valves mainly rely on this equipment for detection, which can reduce the purchase of unqualified products.
Stainless steel valves are usually used in occasions where the working medium has a certain degree of corrosiveness, such as corrosive media, food, medicine, oil, liquid metal and radioactive media and other chemical products. In these fields, any valve material has a relatively limited ability to resist corrosion from the working medium and is affected by many factors. If the processing technology and heat treatment technology used in the manufacturing process are appropriate, the corrosion resistance of this material can be guaranteed. As for 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, when selecting valve materials such as ball valves, gate valves, stop valves and check valves according to the properties of the working medium, it is necessary to simultaneously study the influence of factors such as the concentration, temperature and heat treatment process of the medium on the corrosion resistance in order to select better steel materials such as 316L, 904 or titanium valves.
With the continuous development of petrochemical industry technology and scale, the requirements for stainless steel valves for petrochemical use are getting higher and higher. In addition to continuing to improve the quality of conventional valves such as J41W stainless steel stop valves, Z41W stainless steel gate valves, etc., especially the demand for Q41F stainless steel ball valves for corrosive materials is increasing, such as ethylene cracking units, polyethylene units and polypropylene units in ethylene production, PTA units (purified terephthalic acid), polyester units and polyester spinning units in chemical fiber production, etc. Therefore, efforts should be made to develop corrosion-resistant technology. 316L stainless steel valves have excellent characteristics such as corrosion resistance, high strength, lightness and long service life.
As society progresses, 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 also slowly replace cast iron valves, which brings new opportunities for the stainless steel valve industry and has good market development prospects.
