What is the difference between the connection method of the orifice flange and the ordinary flange? AS2129 TABLE D FLANGE manufacturers tell you that to fix two pipes, pipe fittings or equipment on a flange first, add flange gaskets between the two flanges, and fasten them together with bolts to complete connected.

AS2129 TABLE D FLANGE manufacturers tell you that the orifice flange is the connection of the orifice plate (the measuring part of the orifice plate flowmeter) to the pipeline on the orifice plate flowmeter, and the two-sided flanges fix the orifice plate in the middle. Take the pressure point and lead it to the differential pressure transmitter to measure the flow.
In order to ensure that the installed flange does not leak oil, what problems should be paid attention to during installation? 1. AS2129 TABLE D FLANGE manufacturers tell you that the flange should have sufficient strength and should not be deformed when tightening. The flange sealing surface should be flat and clean, and oil stains and rust spots should be carefully cleaned during installation.
2. AS2129 TABLE D FLANGE manufacturers tell you that flange gaskets should have good oil resistance and anti-aging properties, as well as good elasticity and mechanical strength. For installation, gaskets of different cross-sections and sizes should be selected according to the shape of the connection, and placed correctly. 3. The tightening force of the flange should be uniform, and the compression amount of the rubber pad should be controlled at about 1/3.
The above information is the AS2129 TABLE D FLANGE manufacturer's introduction and analysis of the two questions about flanges, hope it helps you.
