Product introduction
Flange-connected diaphragm seals are a common diaphragm seal device used to protect pressure sensors or transmitters from erosion and damage by process media. It uses a flange connection to fix the diaphragm device on the processing pipeline and ensures the stable and reliable operation of the pressure measurement system by isolating corrosive, high-temperature, or high-pressure process media.
Flange-connected diaphragm seals usually consist of two flanges, a diaphragm, and connecting bolts. The diaphragm is located between the two flanges and isolates the process medium from the sensor, preventing it from direct contact with the sensor surface. Flanges and connecting bolts are used to install the diaphragm seal on the process pipeline to ensure sealing performance and a stable connection.
Diaphragm seals are suitable for various industrial fields, such as chemicals, petroleum, pharmaceuticals, food and beverages, etc., especially when the pressure of corrosive media, high temperature, or high-pressure media needs to be measured. They protect pressure sensors from media erosion while ensuring accurate transmission of pressure signals for process control and monitoring needs.
Advantages of diaphragm seals
● Protect sensitive instrumentation from corrosive, abrasive, or high-temperature process media.
● Accurate pressure measurement in challenging industrial environments.
● Facilitates easy maintenance and replacement of pressure sensors without interrupting the process.
● Compatible with a wide range of process fluids and operating conditions.
Application
Flange-type diaphragm seals are used in a variety of industries, including chemical processing, oil and gas, pharmaceutical, food and beverage, and water treatment. They are suitable for measuring pressure in liquids, gases, or vapors, especially in harsh or corrosive environments where direct contact with the process fluid may damage the sensor.
