WebbFlat-Face Flanges are frequently used where casting is used to make mating flange or flanged fitting and have a gasket surface in the same plane as the bolting circle face. Ring Type Joint Flanges (RTJ) are made … WebbA flat face flange offers increased strength and durability over a traditional raised face flange. This is because there is less surface area for the bolts to grip, making it less likely that they will loosen over time. Reduced Leakage Flat face flanges also help to reduce leakage, as there is no recess for the flat face flange gasket to sit in.

WebbFlat face flanges are by no means to be bolted to a raised face flange. ASME B31. 1 says that once connecting flat face forged iron flanges to carbon metal flanges, the raised face on the carbon metal flange must be removed, and that a full face gasket is needed. WebbFlat faces, counter-bore, o-ring groove, and other styles are available but uncommon in most industries. There are also various styles that attach to pipes differently. That has no affect on the valve ends. The flanges on the valve are usually part of the valve body itself. They mate up with a matching flange that must be attached to the pipe.

WebbFlat face flanges should not be bolted to raised face flanges. A soft type (non-metallic) full-face gasket is generally used between two flat-face flanges while making a joint connection. This type of flange face is also known as a plain face. Flat-face flanges are preferred for low-pressure applications. WebbFlanges Face Types RTJ, Flat, Raised Face.
