Information

The passivation process of flange can be divided into wet method and dry method. Specifically, it can be divided into many types. The passivation of the flange depends on the passivation process and the material itself. The specific influencing factors include the metallographic structure of stainless steel and the processing state of stainless steel. Among the constituent elements, chromium and nickel are elements with strong passivation properties, followed by the passivation properties of iron. Therefore, the higher the content of chromium and nickel, the stronger the passivation properties of stainless steel. Let's follow the editor of WN Flange to see how to do passivation!
The smooth and clean profile of the flange after machining has better passivation, and the profile of the workpiece obtained from forging and sandblasting is rough.
The raw material of the flange not only has a satisfactory creep-breaking curve, but also the price of its pipe is moderate, and the reliable form of mutual fusion and hot-melt connection. The diameter of the pipe fittings should be larger than the inner diameter of the non-specific pipes. The construction is relatively The product is convenient and fast, and the connection form belongs to the current stage. In the system, the fluid resistance of the system is relatively small due to the mechanical connection without local diameter reduction.
The long-lasting pressure resistance of the flange is only from the design stress, and the pressure resistance of the flange is very good. However, due to various factors, the actual wall thickness of the floor heating pipe is usually only 2mm. Under this wall thickness, all kinds of pipes can meet the requirements of floor heating, and the pressure-resistant advantages of flanges can easily not emerge.
In summary, this WN Flange editor tells: how to deal with the knowledge of flange passivation, I hope you can learn more.
