(1) Slip-on Flange:
This flange is slipped over the pipe and then fillet welded. Slip-on flanges are easy to use in fabricated applications.
(2) Blind Flange:
The flange is used to blank off pipelines, values and pumps, it can also be used as an inspection cover, It is sometimes referred to as a blanking flange.
(3) Weld Neck RF Flange:
This flange is circumferentially welded into the system at its neck with means that the integrity of the butt welded area can be easily examined by radiography. The bores of both pipe and flange match, which reduces turbulence and erosion inside the pipeline. The weld neck is therefore favoured in critical applications.
(4) Socket Weld Flange:
This flange is counter bored to accept the pipe before being fillet welded. The bore of the pipe and flange are both the same therefore giving good flow
