What gasket does the 9.8MPa pressure vessel flange seal?
The problem is best to be specific, gasket selection, materials and types, and dimensions to determine the pressure, temperature, medium flange, material type, design requirements and other information to provide good to determine.
You do not know what is the form of flange flange is not installed if ah, then I suggest you install the octagon gasket, see if the installation is a concave convex surface or two convex concave convex surface, if the installation of 10Mpa band steel ring graphite spiral wound gasket, if the steel ring with inner and outer two convex installation 10Mpa the graphite spiral wound gasket
Seal gasket three elements: medium, temperature, pressure. What's your medium? Is it sour or base, organic solvent or water vapor? How high is it? How much pressure? In the gasket selection. If the strong acid, strong alkali and organic solvent temperature is not more than 230 degrees Celsius, the pressure is not more than 4.0MPa, I suggest you use PTFE gasket. If high temperature and high pressure water vapor, that is, high temperature, no more than 600 degrees Celsius, the pressure at 25MPa, it is recommended to use metal wound gasket. Of course, there are also to see your flange form, and there is the implementation of which country standards. Because of this gasket a lot, the most important thing is to choose suitable for their use of gasket. The seal is small, but the role is very, very important. But don't get obsessed with foreign brands, either. In fact, many are produced in mainland china.
What gasket is used for the flange of the 9.8MPa pressure vessel, and what form of flange shall be used to determine the gasket after determining the diameter and temperature of the vessel (and the nature of the medium)?. If the vessel diameter is relatively large, coupled with the 9.8MPa (or small), should adopt the self sealing flange, using triangle aluminum sealing pad, or use such as relatively small diameter, it should adopt the concave convex type or tenon form flange, is copper or aluminum flat gasket commonly used.
