ASTM A105 Orifice Flange

DESCRIPTION:  Hebei Metals supplies the Stainless Steel Orifice Flanges.   The function for the orifice flange is to measure the rate of the flow  of the commodity through the pipeline system. It has a hole drilled  through the face of the flange perpendicular to the pipe with a set of  bolts called jack screws which are used to seperate the flange so  inspection or replacement of the orifice plate can be performed.
