TYPE OF ORIFICE FLANGE:

The Orifice flange could be in many different types, welding neck orifice flanges, slip on orifice flanges or threaded orifice flanges. The sealing face of the orifice flange could be Raised Face(RF) or Ring Type Joing (RTJ).

ORIFICE FLANGES OF HEBEI HAIHAO GROUP:

Commonly we supply the Weld neck and slip on orifice flange in Haihao group, the manufacturing standard is ANSI B16.36. Other types flange is also available to design . when the sizes are more than 24” , we should use the MSS SP-44 as the standard . Bolting position and data will as per ANSI B16.5. Hebei haihao flange factory has enough experienced in design and production about the orifice flanges.
