At this stage, the use of stainless steel valves in our industrial pipelines and civil pipelines has gradually increased. Stainless steel has the characteristics of anti-corrosion, rust prevention, and high strength, and it has also received extensive attention from the industry! Therefore, when general customers require stainless steel, they also need to test the material to see whether the internal content of the stainless steel is qualified. It is the process to satisfy the customer. There are more varieties of stainless steel solar solenoid valve manufacturers, and the price difference is also very large, so sometimes The choice of materials for purchasing valves forms a key factor.
In applications where the working medium is corrosive, stainless steel valves are often used, such as corrosive medium, food, petroleum, chemical products, liquid metal and radioactive medium, etc. Any kind of valve material in the field, the ability to resist the corrosion of the working medium is relatively good Limited and affected by many factors. If the processing technology and heat treatment method used in the manufacturing process are appropriate, the direct-acting solenoid valve manufacturer can guarantee the corrosion resistance of the material. For 98% concentrated nitric acid medium with a concentration> 1, no matter how the heat treatment process is, steel does not have corrosion resistance.
Therefore, when selecting valve materials based on the characteristics of the pilot diaphragm solenoid valve working medium, such as ball valves, gate valves, stop valves, check valves, etc., it is necessary to study the influence of medium concentration, temperature and heat on the corrosion resistance of materials. High-quality steel, such as 316L, 904 or titanium valves.
With the continuous development of technology and scale in the petrochemical industry, the demand for stainless steel valves for petrochemical industry is also increasing. In addition to continuing to improve the quality of conventional valves such as J41W stainless steel globe valves and Z41W stainless steel gate valves, Q41F corrosion materials have a strong effect on Q41F stainless steel. The demand for ball valves is also increasing, such as ethylene cracking plants, polyethylene plants and polypropylene plants, PTA plants (purified terephthalic acid), polyester plants and polyester spinning plants in chemical fiber production. 316L stainless steel valve has the characteristics of corrosion resistance, high strength, light weight, long service life, etc., in order to develop anti-corrosion technology.
After the stainless steel valve is often needed, the quality is definitely no problem! But it often loses the price/performance ratio. Because of the process, because of the cost, the price is limited. While focusing on quality, we also hope to reduce costs and make stainless steel valves the mainstream.
