Stainless steel valves because of its long life, not rust, green and other advantages of excellence has entered the industrial applications, has become the field of pipeline industry will purchase the valve products, but the domestic valve manufacturers to meet international standards is not universal, so Customers in the procurement of stainless steel valves must be required before the business provides a variety of stainless steel valves production and factory certification, can also be used spectrometer for testing, spectrometers for high precision, wide range of applications to be widely used in precious metals and stainless steel valve detection The field of application has also been rapid development in recent years, some 304,316 L valves are mainly dependent on the detection equipment, which can reduce the purchase of substandard products.
Stainless steel valves are usually used in certain corrosive media, such as corrosive medium, food, medicine, oil, liquid metal and radioactive chemical products, in any of these areas valve materials, corrosion resistant working medium Capacity is relatively limited, and by many factors. If the manufacturing process used in the manufacturing process and heat treatment process properly, thus ensuring the corrosion resistance of this material. As for the concentration of> 98% concentrated nitric acid medium, no matter what kind of heat treatment process, the steel does not have corrosion resistance. Therefore, in accordance with the nature of the working medium to choose the ball valve, gate valve, check valve and check valve and other valve materials, the media must also study the concentration, temperature and heat treatment process and other factors on the corrosion resistance to choose more Good steel materials such as 316L, 904 or titanium valves.
With the continuous development of petrochemical technology and scale, the demand for petrochemical stainless steel valves is increasing, in addition to continue to improve the quality of conventional valves such as J41W stainless steel globe valve, Z41W stainless steel gate valve, especially for corrosive materials Q41F stainless steel Increasing demand for ball valves, such as ethylene crackers, polyethylene plants and polypropylene plants in the production of ethylene, PTA plants (terephthalic acid) in the chemical fiber production, polyester plants and polyester spinning units, Should strive to develop corrosion-resistant technology, 316L stainless steel valves with corrosion-resistant, high strength, light, long life and other excellent features.
The industry in the progressive increase in the industry for the use of stainless steel products, the industry is also increasing, new products and new industries will gradually replace the cast iron valves, stainless steel valve industry for new opportunities for the market prospects for development.
