Class 150 Raised Face Slip On Pipe Flange Stainless Steel A182 F316L

Class 150 Raised Face Slip-On Pipe Flange Stainless Steel A182 F316L

Slip-on Flanges are at the low cost end of the scale, and do not require high accuracy when cutting the pipe to length. These SO Flanges can sometimes have a boss or hub, and can be made with a bore to suit either pipe or tube. Slip-on flanges, also known as ‘ hubbed flanges ’, have a hub with a very low profile. This type of flange is usually connected to a pipe by one or two fillet welds (one outside the flange and one inside the flange), it is however possible to use only a single weld.

ASME B16.5 covers flange dimensions from ½” to 24”. Different types of flange faces are used as the contact surfaces to seat the sealing gasket material. ASME B16.5 and B16.47 define various types of flange facings, including the raised face, the large male and female facings which have identical dimensions to provide a relatively large contact area.

The flange face is the surface area that hosts the gasket. The 6 available types of flange face are flat (FF), raised (RF), ring joint (RTJ), lap joint, male and female (M&F), tongue and groove (T&G). Flanges with different faces require different gaskets and shall never be mated to prevent leakage of the joint. RF and FF flanges may have different types of “finish” (i.e. roughness on top the surface): smooth, stock and serrated.
