Characteristics of flange connection
1. Complex but stable structure: Flange connection is formed by connecting two pipes or equipment with flanges, and then tightening the flanges with bolts to form a whole. The structure is relatively complex, but the connection is more stable.
2. Excellent sealing performance: The sealing gasket between the flanges can effectively prevent the leakage of the medium and ensure the safety and stability of the connection. The material of the flange gasket will also be selected according to the pressure level, ranging from low-pressure asbestos pads, high-pressure asbestos pads and PTFE pads to metal pads.
3. Wide range of applications: Flange connection can be applied to pipeline connections of various pipe diameters, various pressures, and various temperatures, especially in harsh environments such as high pressure, high temperature, and corrosion. When choosing a flange, factors such as the pH of the medium should also be considered.
4. Easy disassembly: Although the installation process is relatively complicated, the flange connection is also convenient when disassembling, just loosen the bolts.
Characteristics of clamp connection
1. Simple structure: The clamp connection mainly uses two symmetrical clamps to clamp the pipe or equipment to achieve the connection. The clamp is usually fixed by bolts or other fasteners for easy adjustment and disassembly.
2. Convenient installation: Due to its simple structure, you only need to align the clamp with the pipe or equipment and then tighten the bolts to complete the installation, without the need for professional tools and professionals.
3. Low cost: The cost of accessories for clamp connection is relatively low, and the speed of installing and removing accessories is relatively fast, and the corresponding maintenance cost is also low.
4. Limited application scenarios: The clamp connection is mainly suitable for low-pressure, low-temperature and low-sealing performance requirements, such as drainage pipes. At the same time, there are higher requirements for the medium, such as good lubricity of the medium, smooth surface without scratches and depressions. Generally speaking, the clamp connection is suitable for pipes with a diameter less than DN50.
Differences between flange connection and butt-clip connection
1. Structural complexity: The structure of flange connection is relatively complex, while the structure of butt-clip connection is relatively simple.
2. Sealing performance: The sealing performance of flange connection is better than that of butt-clip connection, especially in high pressure and high temperature environment.
3. Installation convenience: Butt-clip connection is more convenient during installation, while flange connection requires more precise docking flange and ensures that the sealing gasket between flanges is correctly placed, so the installation process is relatively complicated.
4. Scope of application: Flange connection is suitable for pipeline connection in various harsh environments, while butt-clip connection is mainly suitable for low pressure, low temperature and low sealing performance requirements.
5. Cost and maintenance: The cost of butt-clip connection is relatively low, and the maintenance cost is also low; while flange connection requires precise construction technology and precision equipment during construction, so the investment in manpower, material resources and time is large, and its maintenance cost is correspondingly high.
Flange connection and butt-clip connection each have their own characteristics and applicable scenarios. When selecting a connection method, comprehensive consideration should be given to specific needs and actual working conditions to ensure the safety and reliability of the pipeline or equipment connection.
