• Weld neck
A welding neck flange (“WN”) is a long-tapered hub which can be welded with a pipe. This flange type is used, normally, in dynamic-pressure & high/low temperatures applications that require an unrestricted flow of the fluid conveyed by the piping system (the bore of the flange matches with the bore of the pipe).

• Slip on
A slip-on flange is connected to the pipe or the fittings with the help of two fillet welds, one executed inside & one outside the cavity of the flange. The bore size of a slip-on flange is gigger than the outter diameter of the connecting pipe, as the pipe has to slide inside the flange to be connected by the execution of a fillet weld.

• Lap joint
Lap joint flanges feature a flat face & are always used in conjunction with a stub end. Lap joint flanges appear likes, in shape, slip-on flanges except for the radius at the crossing of the flange face & the bore to accommodate the flanged portion of the stub end.

• Threaded
Threaded flanges are connected to pipes by screwing the pipe (which has a male thread, generally NPT per ASME B1.20.1) onto the flange, without seam welds (in certain cases, though, small welds are applied to increase the strength of the connection).

• Blind
Contrary to all the different types of flanges seen above, blind flanges do not have a center hole, & are used to blind or seal a pipeline, a valve/pressure vessel & block the flow of the fluid. Blind flanges have to withstand remarkable mechanical stress due to the system pressure & the required bolting forces.

• Socket weld
A flange is an external or internal ridge, or rim, for strength, as the flange of an iron beam such as an I-beam or a T-beam; or for attachment to another object, as the flange on the end of a pipe, steam cylinder, etc.
