Flange Type: Threaded Flange
The threaded flange manufactured in accordance with ASME B16.5 is similar to the slip on flange, but the bore shall have a taper pipe thread conforming to ASME B1.20.1. The thread shall be concentric with the axis of the flange opening, and variations in alignment (perpendicular to the flange face) shall not exceed 5 mm per meter. Threaded flanges are available in sizes NPS 1/2 through NPS 24 for pressure ratings of Class 150, Class 300, Class 400, Class 600 and Class 900. Sizes for Class 1500 and Class 2500 are available from NPS 1/2 to NPS 2-1/2.
Class 150 threaded flanges are made without a counter bore. The threads shall be chamfered approximately to the major diameter of the thread at the back of the flange at an angle of approximately 45 degree with the axis of the thread. The chamfer shall be concentric with the thread and shall be included in the measurement of the thread length. Class 300 and higher pressure class flanges shall be made with a counter bore at the back of the flange. The threads shall be chamfered to the diameter of the counter bore at an angle of approximately 45 degree with the axis of the threads. The counter bore and chamfer shall be concentric with the thread.
