Eccentric reducer pipe fitting is a special pipe fitting mainly used to connect two pipes of different diameters. It is designed so that the center lines of the pipes are not collinear, which helps to eliminate vortexes, reduce fluid resistance in the pipe, and prevent cavitation when used at the inlet of the pump.
Material
The Eccentric reducer pipe fitting materials provided by Junrui are mainly made of PVC and HDPE. The main differences lie in their physical properties, chemical resistance, service life and application fields.
1. Physical properties: Eccentric reducer pipe fittings made of PVC usually have good flexibility and corrosion resistance, which makes them suitable for occasions where pipes of different diameters need to be bent or connected. Eccentric reducing pipe fittings made of HDPE are known for their high density and excellent wear resistance. They can remain stable under high pressure and harsh environments and are suitable for occasions that need to withstand high pressure and wear.
2. Chemical corrosion resistance: PVC material has good resistance to a variety of chemical substances, including acids, alkalis, salts, etc., so it is suitable for a variety of industrial environments. HDPE material also has good chemical resistance and can resist the erosion of most chemical media, including chemicals other than strong oxidants.
3. Service life: Since both PVC and HDPE have excellent aging resistance and can be used in outdoor environments for a long time without being easily affected by factors such as ultraviolet rays and oxidation, Eccentric reducer pipe fittings made of both materials have relatively long service life. Long service life.
4. Application fields: PVC eccentric reducing pipe fittings are widely used in building water supply and drainage, chemical pipelines, wire and cable protection and other fields due to their good flexibility and corrosion resistance. Because of its excellent wear resistance and high density, HDPE eccentric reducer fittings are mainly used in industrial pipeline systems that are required to withstand high pressure and wear, such as drainage, water supply pipelines, and engineering power cable protection.
How to choose an Eccentric reducer pipe fitting?
1. Determine the working conditions of the pipeline: including pressure, temperature, medium and other factors. These factors directly influence the selection of eccentric reducers, as different operating conditions may require different materials and designs.
2. Select the appropriate material: Select the appropriate pipe material according to the pressure and temperature conditions.
3. Determine wall thickness and length: Select the appropriate wall thickness and length based on factors such as the flow rate, flow rate, and flow pattern of the pipeline. This requires consideration of the structural and design requirements of the pipeline.
4. Comprehensive consideration of economy: Consider factors such as the service life of the pipeline, maintenance and replacement costs, etc., and comprehensively select the wall thickness and length with good economics.
5. The selection of Eccentric reducer pipe fitting should also consider the requirements of the process flow chart or the requirements of the piping layout. For example, the horizontally placed reducer on the pipe gallery is usually a flat-bottomed eccentric reducer, while the inlet pipe of the pump is usually selected. Eccentric reducer with flat top.
