Pressure tapping method for orifice plates
Thread Content
For orifice plates with a small diameter of DN300 or less, the corner connection method is generally used for pressure measurement; for those even smaller, a ring chamber is employed for this purpose. For larger orifice plates, the D-D/2 method is often used. These methods are applicable to gases, while for liquids and steam, the corner connection method is used. If the operating pressure is high within the range of 100–300, it is also advisable to use the corner connection method rather than the D-D/2 method Regarding the detailed classification of pressure tapping methods and related experience, I hope those who understand this topic can provide a clear explanation. Let’s all analyze it together
Considering maintenance and disassembly, we opt for flange pressure tapping when making selections; of course, for sizes below DN100, corner connection pressure tapping needs to be considered.
