Carbon steel orifice flange, The connection mode is different from that of ordinary flange. The orifice plate flange is the orifice plate connected to the pipeline by the orifice plate flowmeter. The orifice plate is fixed in the middle by the flanges on both sides, and is led to the differential pressure transmitter through the pressure taking point on the flange to measure the flow.

Carbon steel orifice flange shall ensure that the center of orifice plate, flange center, pipe center and gasket are concentric, and the different centrality shall not exceed 0.002d/ β, The positive and negative pressure direction of the orifice plate shall be consistent with the flow direction of the medium.
Carbon steel orifice flange is a component of orifice flowmeter, which appears in pairs. The material flow can be calculated according to the formula by using the pressure difference on both sides of the flow orifice.
