Customizable and wholesale price flange

Short Description:

Orifice flanges are usually applying for metering the volumetric flow rate of liquids and gasses through a pipe. Two orifice flanges are called an orifice flange union. Each flange comes with two pipe taps for measuring the pressure drop of the flow through an orifice plate. Orifice plates do not come with the flanges and are sized based on the requirements of the process. Two jack screws are used to spread the flanges apart in order to change the orifice plate. This flange is normally available in weld neck, slip-on, and threaded flanges. Orifice flanges generally have a raised face.

Dimensions of PN 10 Flanges EN 1092-1

NOTE 1: Dimensions N1, N2 and N3 are measured at the intersection of the hub draft angle and the back face of the flange.
NOTE 2: For d1 dimensions see document "Flange facing according to EN 1092-1".

Dimensions in mm

* For flanges type 21 the outside hub diameter approximately corresponds to the outside pipe diameter.
NOTE: The p/t ratings from EN 1092-1 apply only for flange types 05, 11, 12, 13 and 21 having nominal sizes up to and including DN 600. The p/t rating of all other flanges shall be agreed between the manufacturer and the purchaser.
