Flanges Applications
Types of Flanges: Uses:
Weld neck flange High pressure, cold or hot temperature.
Slip-on flange To prevents leaks.
Threaded flange Not involving temperature or
stresses of any magnitude.
Lap joint flange Requiring frequent
dismantling for inspection.
Reducing slip-on flange Reduction is to be made.
Slip-on(Socket weld) flange Avoiding leakages.
Blind flange To close ends of piping systems.
Long weld neck Used for nozzles on pressure vessels.
Orifice flange Flow of liquids & gases through pipe line.
