What is BS 4504 Flange?
The BS 4504 specification covers plain, casted, forged, boss, and weld-neck flanges. Basically. The BS 4504 forged Flanges have become obsolete, but they are in use for light duty applications. They are one of the best economical stainless steel flanges used in service where corrosion resistance and hygiene are optimal. Unlike the conventional flanges, they are not used in high temperature or high pressure applications.
The BS 4504 Flanges are available in different types, and their dimensions can be customized according to specific requirements. Their surface treatments can also be customized as required by the buyer. The BS 4504 Flanges are manufactured using one or more of the given techniques: forging, machining, and heat treatment. Apart from these, the stamping process is also used for BS 4504 Flange.
The BS 4504 Flanges are primarily used in heavy industries, like bitumen upgraders, nuclear power plants, acid production, shipbuilding, offshore, natural gas, and many more.

BS 4504 PN10 Vs PN16 Flange
The difference between BS 4504 PN10 Flange and BS 4504 PN16 Flange are in their nominal pressure (PN). The nominal pressure ofBS 4504 PN10 Flange is 10 bar, and that of BS 4504 PN16 Flange is 16 bar. Thus PN 16 flange is stronger than Pn 10 flange with a higher pressure rating, and the former is capable of withstanding higher pressure at a given temperature.

Different BS 4504 Flanges Facing Types
Different BS 4504 Flanges Facing Types would include Raised Face (RF), Flat Face (FF), Lap-Joint Face (LJF), Ring Type Joint (RTJ), Large Male-Female (LMF), Small Male-Female (SMF), Small Tongue & Groove, Large Tongue & Groove.

Where to use BS4504 PN6 Flange?
The BS4504 PN6 weld neck Flange is widely used in heavy oil refineries, bitumen upgraders, petrochemical, acid production, and the seamless ones are used in nuclear power plants.
