Dear, hello, I am glad to answer for you: The implementation standard of 304 stainless steel Li Noise clean quick-assembly ball valve is as follows: the new national standard 304 stainless steel pipe GB T14976-2012304 stainless steel pipe is a grade of stainless steel in accordance with the American ASTM standard.

304 stainless steel pipe is equivalent to 0Cr18Ni9 stainless steel pipe in China, with 17% chromium and 8% nickel. China's new standard 304 stainless steel is 06cr19ni10, containing 17% chromium and 8% nickel, also known as American standard 304 or stainless steel pipe The national standard is, the specification and thickness:

Summary. Dear, hello, talking about the valve body, pneumatic ball valve is a kind of pneumatic actuator widely used in modern automatic control system. The control signal drives the ball valve to switch through the pneumatic actuator to complete the on/off control or adjustment control of the medium in the pipeline.

304 stainless steel pneumatic ball valve is said to be 304 valve body or valve core is 304 kiss, you are good, talking about the valve body, pneumatic ball valve is a kind of pneumatic actuator widely used in modern automatic control system. The control signal drives the ball valve switch action through the stool key state pneumatic actuator to complete the switch control or adjustment control of the medium in the pipeline.

Pneumatic ball valve selection should consider the factors of ball valve, cylinder and accessories, and when each choice of return socks is lost and dismantled, it will have an impact on the use of pneumatic ball valves, sometimes small. In some cases, it is not possible to meet the process requirements. Therefore, it is necessary to know the process parameters and requirements when selecting the model.

The safety valve is an important fluid control safety equipment in the industrial production process, so the selection of the safety valve material is the basis for the selection of the safety valve.

Features of stainless steel 304 safety valve:

304 is a versatile stainless steel that is widely used in equipment and parts that require good overall properties (corrosion resistance and formability). In order to maintain the corrosion resistance inherent in stainless steel, the steel must contain more than 18% chromium and more than 8% nickel. 304 stainless steel is a grade of stainless steel produced in accordance with the American ASTM standard.

Chromium-molybdenum steel and 304 steel are hard

Chromium-molybdenum steel is an alloy of chromium (Cr), molybdenum (Mo), iron (Fe) and carbon (C). Good quenchability, can be deep quenching, instead of the surface quenching of anti-saw-shaped locks on the market, due to its special high-quality performance, it is often used in the manufacture of some high-temperature, high-pressure resistant valves and pressure vessels, such as chromium-molybdenum steel safety valves, chromium-molybdenum steel gate valves, screwdriver bits, bicycles, etc. 304 is a versatile stainless steel that is widely used in equipment and parts that require good overall properties (corrosion resistance and formability).

In order to maintain the corrosion resistance inherent in stainless steel, the steel must contain more than 18% chromium and more than 8% nickel. 304 stainless steel is a grade of stainless steel produced in accordance with the American ASTM standard. Chromium-molybdenum steel can be quenched to improve the hardness, but 304 cannot be quenched, so the hardness of chromium-molybdenum steel is higher than that of 304.

Safety valve material

Safety valve is an important fluid control safety equipment in the industrial production process, so the selection of safety valve material is the basis for the selection of safety valve, if there is no correct material selection, there is no way to talk about the safety of safety valve, the following will be commonly used safety valve material selection to make an overview.

1. For low-pressure and normal temperature ordinary media with less than pressure, such as water, air, oil source products, etc., gray cast iron, brass, cast steel and other materials can be selected;

2. For the pressure of high-pressure and normal temperature ordinary media, such as water, air, oil, gas, etc., cast steel can be selected;

3. For high-pressure and normal temperature corrosive media, such as acetic acid, hydrochloric acid, sulfuric acid, etc., stainless steel materials can be selected;

Fourth, for the pressure of high pressure, high temperature and temperature ordinary media, such as water, air, oil, steam, etc., you can choose high temperature steel material.

1.Ingredient Differences:

The 304 stainless steel body contains 18% chromium and 8% nickel, which is an ordinary stainless steel material with good corrosion resistance and weldability; The 316 stainless steel body contains 16% chromium, 10% nickel and 2% molybdenum, which has better corrosion resistance and high temperature resistance.

2.Performance Differences:

In most cases, the 304 stainless steel valve body can meet the general use requirements, but in some harsh working environments such as strong acid, strong alkali, high temperature, high pressure, etc., corrosion or deformation may occur; The 316 stainless steel valve body can better resist these harsh working conditions, so it has been widely used in some chemical, marine, medical and other fields.

Therefore, when choosing the flanged stainless steel valve body, it is necessary to choose the appropriate material according to the actual working environment and requirements to ensure the normal operation and service life of the valve.

Stainless steel ball valves are generally used in the following standards. (Excludes standards such as flanges, threads, and welds used for connections; and the standards to which the material is subject; and special industries such as food, pharmaceutical, oilfield, fire protection requirements for valves).
