Stainless Steel/Carbon Steel/Alloy Flange

The flange is a part connected between the pipe and the pipe, which is used for the connection between the pipe ends; It is also useful in the flange on the import and export of the equipment for the connection between two devices, such as the reducer flange. Flange connection or flange joint refers to a detachable connection which is connected by flanges, gaskets and bolts as a group of combined sealing structures.

Flange facing There are three primary types of flange facings. Not all facings are available with each end connection. This is based on the design of the flange and design of the piping system.

Flange pressure classes

Flange types
	Blind flange A blind flange, abbreviated as BF, is a piping component for covering or closing the end of a pipe, valve, vessel or tank.
	Lap joint flange A lap joint flange, abbreviated as LJF, is a flange that consists of two parts, a stub end and the backing flange. In general, the thickness of the hub is between ¼” to 3/8”.
	Raised face flange the most common type of flange facing is the raised face flange, abbreviated as RF. It is used in almost all applications in high and low pressures and temperatures. The face of the flange is either 1/16” or 1/4” depending on the pressure class. ANSI 300 and under have a 1/16” raised face and ANSI 400 and above have a 1/4” raised face.
	Slip-on flange Slip-on flanges, abbreviated as SOF, are designed to slip over the outside of pipe, long-tangent elbows, reducers, and swages.
	Thread flange The threaded flange, abbreviated as TRHF, is similar to a slip-on flange, but has internal threads. It is normally used for low pressure and not used where temperature or stress is very high. This flange has a raised face.
	Socket weld flange The socket weld flange, abbreviated as SWF, is similar to a slip-on flange, except only one fillet weld is made to the flange and pipe. Pipe is welded to socket weld flanges by inserting the pipe into the socket and backing the piping out between 1/16” and 1/8”.
	Weld neck flange the weld neck flange, abbreviated as WNF, is a flange type that is usually used with pipes, as opposed to pressure vessels.
