UNS S32205 DN250 Duplex 2205 Stainless Steel Orifice Flange Class 150
UNS S32205 DN250 Class 150 duplex 2205 Stainless steel orifice flange
Description
Stainless steel orifice flange is a component of orifice flowmeter, which is usually used in pairs. The orifice flowmeter is a component that measures the pressure difference on both sides of the flow orifice, and can calculate the material flow according to the formula. Orifice flowmeter includes flow orifice, orifice flange, impulse pipe, transmitter, etc.

Characteristic
Stainless steel orifice flange shall ensure that the orifice center, 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, the upstream and downstream pressure taking flanges shall be consistent with the flow direction of the medium, and the orientation of the pressure taking hole can be determined according to different media and the installation of the transmitter.
Application
Stainless steel orifice flange is used in petroleum, chemical industry, nuclear power plant, food manufacturing, construction, shipbuilding, papermaking, medicine and other industries.
