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.

Stainless Steel/Carbon Steel/Alloy Reducer
Concentric reducer is a kind of fitting that be used for reducing piping size. Concentric reducer is most commonly used and often eccentric reducer used in piping in about pump and pipe rack area.</br> Eccentric reducer is most commonly used and often eccentric reducer used in piping in about pump and pipe rack area.</br> These reducers are used in various applications that involved in high pressure, vibration & temperature. These reducers are widely used in chemical, petroleum, shipbuilding, gas, power sectors.

Stainless Steel/Carbon Steel/Alloy Tee
Tee is also known as tee or tee pipe fittings, tee joints, etc. Mainly used to change the direction of the fluid, used in the main pipe to branch pipe. Can be classified by pipe size. Generally made of carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon, pvc and other materials.

Stainless Steel/Carbon Steel/Alloy Elbow
An elbow is a pipe fitting installed between two lengths of pipe or tubing to allow a change of direction, usually a 180° or 90° angle, though 45° elbows are also made. The ends may be machined for butt welding (SW) or socketed welding(SW) etc.
