Nowadays, flange connection is used in many working condition sites, especially in industrial production workshops like petroleum and chemical industries, where process pipelines, measuring instruments, transmitters, etc. can be seen everywhere. These pipeline connections, transmitter installation are inseparable from the flange. Flanges have become one of the most common types of chemical equipment piping connections. This is related to the characteristics of flange connection. Simply put, the flange connection is the pipeline, pipe fittings or transmitters and other instrumentation equipment, fixed in a flange, and then between the two flanges plus flange gasket, and finally bolts to the two flanges tighten to make it a combination of a removable joint. Transmitter flange connection considerations are first pressure, and then to meet the pressure requirements under the premise of temperature, media, toxic and hazardous media and other factors. In the process of using the transmitter, the flange connection has high reliability, easy to install and dismantle and other characteristics. In the process of using the flange connection of the transmitter, there are single flange and double flange. Single flange refers to the positive pressure side of the transmitter is a flange structure, directly connected to the interface with the measurement medium, while the negative pressure side is the use of the pilot tube will be connected to the measurement medium and the transmitter chamber. Advantage is that the measurement accuracy is high, can achieve the measurement of technical indicators of the transmitter, the disadvantage is that the negative pressure pipe must be absolutely sealed, and need to transmitter range migration, calibration should be negative pressure pipeline within the media liquid error migration off. Double flange refers to the positive and negative pressure side of the transmitter are flange structure, can be directly connected with the container and pipeline to be measured. The advantage is easy to install, convenient calibration, without range migration. Since the flange is connected with the transmitter by an elastic hose, the interior is filled with silicone oil.
