In the industrial field, the connection of pipeline systems is crucial, and Special Flange plays an indispensable role in it. Special Flange， The special flange, as a component with flange joints, although has a similar bolt connection structure to the standard flange, has its own unique characteristics and diverse types.
Taking orifice flanges as an example, they usually have convex or ring connecting surfaces (RTJ). Orifice flanges can be divided into three types: butt welding, flat welding, and threaded connection, each equipped with a pair of pressure interfaces for measuring the pressure drop of fluid passing through the orifice plate. Long diameter butt welded flanges, also known as high neck flanges, play a critical role in some special application scenarios. It can effectively transmit stress to the pipeline, reduce high stress concentration at the bottom of the flange, and ensure the safe operation of the pipeline system under complex working conditions such as high pressure and high temperature.
Variable diameter flange is another important special type of flange. It plays a crucial role in projects that require connecting pipes of different sizes. The variable diameter flange consists of a flange body with a specific diameter and a smaller diameter inner hole. In addition to the inner hole and neck size, its overall size matches the larger pipe diameter. This design enables a smooth transition when the pipeline size changes, avoiding unnecessary turbulence caused by sudden changes in pipe diameter. However, in equipment such as pumps that require high fluid stability, it is generally not suitable to use variable diameter flanges to avoid affecting the normal operation of the equipment.
In practical applications, the use of Special Flange greatly improves the safety and reliability of pipeline systems. In the petrochemical industry, flammable, explosive, and corrosive media often flow through pipelines, with high operating pressure and temperature. At this point, the sealing performance and corrosion resistance of special flanges become particularly important. By carefully selecting appropriate types and materials of Special Flanges, and strictly installing and maintaining them according to standards, it is possible to effectively prevent medium leakage, avoid safety accidents, and ensure the continuity of the production process. In some high-temperature and high-pressure steam pipeline systems, long diameter butt welded flanges can withstand enormous pressure and thermal stress, ensuring safe and stable steam transportation.
The development of Special Flanges is closely related to the advancement of industrial technology. With the continuous improvement of pipeline system requirements in modern industry, Special Flange is also constantly innovating and improving. In the future, Special Flange will develop towards greater efficiency, intelligence, and environmental friendliness. By adopting new materials and advanced manufacturing processes, its performance and reliability can be improved; With the help of IoT technology, real-time monitoring and intelligent management of the operating status of special flanges can be achieved, and potential problems can be discovered and solved in a timely manner.
The Special Flange may seem like a small component in a pipeline system, but it plays a crucial role in ensuring the safe, stable, and efficient operation of industrial production. With the continuous advancement of technology, it will inevitably demonstrate greater value in more fields and promote industrial development to new heights.
