characteristic endocentric construction
The central axis of the concentric reducer is coincident, which is a structural characteristic that causes the flow direction of the fluid inside the pipeline to always change along the central axis of the pipeline. This is beneficial for maintaining laminar flow of fluids, especially when transporting viscous fluids such as crude oil, heavy oil, etc. It can reduce the degree of fluid turbulence, lower energy loss, and also avoid problems such as wear and corrosion caused by fluid impact on the pipe wall.
Diverse manufacturing processes
The manufacturing process of concentric reducers includes stamping, forging, welding, etc. Stamping technology is suitable for the manufacturing of thin-walled concentric reducers, with high production efficiency; The forging process can produce high-quality and strong concentric reducers, which are suitable for occasions with high quality requirements for pipe fittings; The welding process can combine pipes of different shapes and sizes into concentric reducers, which has high flexibility and can meet the production of various special specifications and requirements.
Advantage
Low fluid resistance
The design of concentric reducers enables fluid to transition smoothly through the pipe fittings. Because its internal structure is concentric, the flow direction of the fluid changes gradually, which greatly reduces local resistance loss compared to the sudden diameter change of pipeline connection. For example, in fluid mechanics experiments, by comparing concentric reducers with simple pipe diameter abrupt connections, the local resistance coefficient of concentric reducers can be reduced by about 30% -50% at the same flow rate, which helps to improve the transportation efficiency of the entire pipeline system and reduce energy consumption.
Good connection stability
Concentric reducers are usually connected to pipelines through welding or flange connections. Welding connections can provide high connection strength, ensuring the sealing and stability of pipeline systems under high pressure, high temperature and other working conditions. Flange connections are easy to install and disassemble, which is very advantageous for pipeline systems that require regular maintenance or replacement of equipment. Moreover, due to its symmetrical structure, it is subjected to uniform forces during installation and can better withstand axial and radial forces in the pipeline system.
Strong adaptability
Can adapt to the connection requirements of various pipe diameter combinations. Suitable connection solutions can be provided regardless of whether the difference in pipe diameter is small or large. And it can be matched with pipes of different materials. As long as the connection method and material compatibility are handled properly, it can play a role in various complex pipeline systems, such as transitional connections in mixed pipeline systems with both carbon steel and stainless steel pipes.
