The flanges of the Mechanical Department and the Chemical Department have significant differences in many aspects, which are mainly reflected in their use, Material, structure and Pressure grade.
1. Purpose:
Mechanical flange: mainly used for general pipeline connections, suitable for low-pressure, low-temperature, non corrosive fluid pipeline systems, such as water supply, steam, air conditioning, ventilation and other pipeline systems.
Ministry of Chemical Industry flange: It is specifically used for connecting chemical equipment and chemical pipelines, suitable for complex conditions such as high pressure, high temperature, and strong corrosion. It is widely used in the fields of petroleum, chemical, pharmaceutical, etc.
2. Material
Mechanical part flange: usually made of carbon steel Material, which is relatively soft, but can meet the strength and sealing requirements of general pipeline connection.
The flanges of the Ministry of Chemical Industry: high-strength Material, such as stainless steel, are used to meet the use requirements under complex working conditions. These Material have good corrosion resistance and high temperature and high pressure bearing capacity.
3. Structure
Mechanical department flange: The structure is simple, mainly composed of basic components such as flange plate, flange gasket, bolts, nuts, etc.
Chemical Department flange: The structure is relatively complex, including basic components such as flange plates, flange gaskets, bolts, nuts, etc., as well as additional components such as sealing rings and flanges to enhance its sealing and load-bearing capacity.
4. Pressure rating
Flange of mechanical department: the Pressure is generally between PN10 and PN16, which is applicable to low-pressure pipeline system.
Flange of the Ministry of Chemical Industry: the use of Pressure can reach PN64 or even higher, which can meet the requirements of high-pressure pipeline system.
The flanges of the Ministry of Machinery and the Ministry of Chemical Industry are significantly different in terms of use, Material, structure and Pressure grade. Therefore, when selecting flanges, it is necessary to comprehensively consider the specific pipeline system and usage conditions to ensure that the selected flanges can meet the requirements of system operation safety and stability.
