Orifice Flange

ASTM A182 SS 304 Orifice Flanges, Monel 400 Orifice Flanges, Alloy 20 Orifice Flanges, Nickel 200 Orifice Flanges, Inconel 600 Orifice Flanges, ASTM A105 Orifice Flanges, Inconel 625 Orifice Flanges, Hastelloy C276 Orifice Flanges, UNS S32760 Orifice Flanges, PED Approved Orifice Flanges, Duplex 31803 Orifice Flanges, 304 Stainless Steel Orifice Flanges.

Orifice Flange helps to measure the flow of liquids and gases using orifice meters located on the outside diameter of the flanges. The main purpose of the orifice flange identifies the flow rate of either liquid or gas in the pipeline system. It comes with either raised faces or RTJ facings. Each orifce Flange come in contact with two pipes taps for measuring the pressure drop of the flow through an orifice plate.

The range of orifice flange covers all standard materials, size, grades and specification. JF Engineering is the best organization of providing the best qualitative product at a reasonable rate. Orifice Flanges are available in ANSI classes 300, 600, 900, 1500 and 2500 in varieties of materials such as stainless steel, carbon steel, alloy steel, monel and Inconel.
