What is a metal gasket? The role of the gasket | Flange Metallic Gasket
There are various types of gaskets. Gaskets are made of metal, semi-metal and non-metal plate materials through cutting, stamping or cutting processes. They are used for sealing connections between pipes, parts and machines of machinery and equipment Sealed connections between components.
According to the material, it can be divided into three categories: non-metallic, semi-metallic and metal gaskets.
What is the function of the gasket, and why is it best to install it in front and back?
If the gasket has a relatively smooth surface and a relatively rough surface (relatively speaking), how much effect can actually be brought by putting the relatively rough surface close to the surface to be fastened?
When installing flat washers with nuts, you will more or less encounter the problem of front and back installation: the smooth side and the rough side (opposite), which side should be closer to the part is better, and what is the big difference?
It is better if the smooth side is close to the surface of the part. (There are many types of gaskets, the following gaskets are all flat gaskets)
The role of the gasket
There are various types of gaskets. Gaskets are made of metal, semi-metal and non-metal plate materials through cutting, stamping or cutting processes. They are used for sealing connections between pipes, parts and machines of machinery and equipment Sealed connections between components.
Among the screws with nuts, the main function of the gasket is to increase the contact area, reduce the pressure, prevent loosening, and protect parts and screws.
The main function of the gasket is to increase the contact area between the bolt or nut and the surface of the part to prevent the surface of the part from being worn out; the second is to make a spring washer to prevent loosening. In addition, it should be noted that the strength and thickness of the gasket have certain requirements.
The position of the spring washer is in the middle of the bolt head and the flat washer, and it is not in contact with the parts. Its function is: using the elastic characteristics of its own material, the opening supports the bolt head and the flat washer respectively (commonly speaking, the opening part Up and down to withstand), use is not easy to loosen and fall off.
The position of the flat washer is under the spring washer. After installation, it is in contact with the spring washer and the connected part. Its function is: 1. Increase the contact area with the connected part; 2. Disperse the pressure on each square area; 3. , Prevent scratches by connected workpieces.
