Flange connected diaphragm seal
application Chemical industry Petrochemical Industry Suitable for corrosive, high viscosity, crystallization and high temperature pressure medium Functional characteristics The flat diaphragm connected to the flange body. Can provide a variety of common standards and nominal diameter All liquid connection parts (diaphragm and sealing surface) can be selected by users of special materials describe Diaphragm seals can protect the measuring instrument from erosion, viscosity, crystallization, corrosion, high viscosity, harmful to the environment or toxic medium. The diaphragm made of suitable material can separate the measuring instrument from the measured medium. Therefore, as long as equipped with appropriate diaphragm seal, the measuring instrument can be used for the highest difficulty measurement task. The filling liquid in the system (which can select the most suitable liquid according to the specific application) can transmit the pressure to the measuring instrument in a hydraulic way. We can provide different design and material diaphragm seal to meet all application requirements. When choosing diaphragm seals, users need to pay attention to two important standards: one is the type of process connector (flange, thread and aseptic connector); the other is the basic manufacturing method. For more technical information on diaphragm seal and diaphragm seal system, refer to IN 0.06 "diaphragm seal"". Type 990.27 diaphragm seal is designed with flange connection and diaphragm, which is suitable for all the standard flanges, and can be installed in the pressure measuring instrument without blind flange. Diaphragm seal and measuring instrument can be assembled directly (standard), and can be assembled by cooling element or flexible capillary. In the selection, Wickham offers a variety of solutions on the sealing diaphragm cavity and the diaphragm can be made of the same or different materials. The membrane and sealing surface can also be sprayed or coated. The measurement system equipped with Wickham seal type 990.27 diaphragm has been in the global scope for success has higher measurement requirements of the chemical and petrochemical industry.
