Threaded Flange ANSI/ASME
Walmi manufacture threaded flange as per ANSI/ASME B16.5. Threaded flange is also named screwed flange, which has a threaded bore and the bore is fractionally larger than the outside diameter of pipe which it is to be fitted, and the pipe has external threads, then it can be assembled with the pipe without welding.
Walmi typically supply threaded flange with a raised face (RF), flat face (FF) or Ring Type Joint (RTJ) face. The standard raised face height is 1.6mm (1/16″) for socket welding pipe flanges under 400#, 6.35mm(1/4″) for 400# and up.
The dimensions of threaded flanges are similar with slip-on flanges, but threaded flanges are often used for small diameter and low pressure requirements, which are not suitable for applications where heating or stresses are present, because leakage through the threads is possible.
