Classification and introduction of water pump flange
The pump flange is a key component connecting the pump and the pipeline, and it plays a vital role in the industrial field. The following is the classification and detailed introduction of the pump flange:
1. Classification
The pump flange can be divided into many types according to the structure, connection method and applicable scenarios. The following are some common classification methods:
Classification by connection method
Welded flange: including flat welding flange and butt welding flange. Flat welding flange is usually used for medium and low pressure process pipelines. The flange is put on the pipe end and welded and fixed; butt welding flange has high strength, is not easy to deform, has good sealing performance, and is suitable for pipelines with high pressure, high temperature and corrosive fluids.
Threaded flange: It is connected to the pipe end thread through a threaded flange, which is divided into low pressure and high pressure. Low-pressure threaded flanges were once widely used, but with the development of industry, they were gradually replaced by flat welding flanges; high-pressure threaded flanges occupy an important position in modern industrial pipeline connections.
Clip flange (also called snap-on flange, quick-connect flange): This flange connection method is simple and fast, and is often used in low-pressure, small-diameter conveying systems. It does not require sealing gaskets and bolts, but the sealing performance is relatively poor.
Plate flange (also called flat flange or flange flange): The connection surface is flat or boss-shaped, which is suitable for pipelines with low pressure, non-corrosive fluids and high pressure, high temperature, corrosive fluids. Sealing gaskets are required when using, and sometimes bolts are required to fix them.
Classification by material
Flanges are made of various materials, including carbon steel, alloy steel, stainless steel, etc. Flanges of different materials have different corrosion resistance and pressure resistance, and are suitable for different working environments.
2. Detailed introduction
Welding flange
Flat welding flange: One of the most commonly used flanges for medium and low pressure process pipelines, with simple connection and low cost. However, its pressure resistance and sealing performance are relatively limited.
Butt welding flange: Suitable for pipeline connection of high pressure, high temperature and corrosive fluids. It has high strength and good sealing performance, but the manufacturing cost and installation difficulty are relatively high.
Threaded flange
Low-pressure threaded flange: Once widely used in industrial pipeline connection, but with the development of welding technology, its application has gradually decreased.
High-pressure threaded flange: An important choice in modern industrial pipeline connection, with excellent sealing performance and pressure resistance.
Clamp flange
Suitable for low-pressure, small-caliber conveying systems, easy and quick to connect, but relatively poor sealing. Suitable for occasions where sealing is not required.
Plate flange
Flat flange: The connection surface is flat and suitable for pipelines with low pressure and non-corrosive fluids. Sealing gaskets need to be added during installation to ensure sealing performance.
Flange flange: The connection surface is in the shape of a boss and is suitable for pipelines with high pressure, high temperature and corrosive fluids. Its sealing performance is better than that of flat flanges, but the manufacturing cost and installation difficulty are also relatively high.
In summary, there are various types of water pump flanges, and different types of flanges have different characteristics and scope of application. When choosing a water pump flange, it is necessary to choose the appropriate type and material according to the specific working environment and requirements. At the same time, it is also necessary to pay attention to the manufacturing quality, installation accuracy and maintenance of the flange to ensure the safe and reliable operation of the water pump system.
