- Flat face flanges may be provided at full thickness,C,or with raised face removed (the latter is nonstandard).
Specifications of ANSI/ASME B16.5 forged flange:
Types of ANSI/ASME B16.5 forged flanges:
 ANSI ASME B16.5 weld neck flange drawing |
Weld neck flange(WN flange) is circumferentially welded into the system at its neck which 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. |
 ANSI ASME B16.5 blind flange drawing |
Blind flange is used to blank off pipelines,valves and pumps,it can also be used as an inspection cover.It is sometimes referred to as a blank flange. |
 ANSI ASME B16.5 slip on flange drawing |
Slip on flange(SO flange) is slipped over the pipe and then fillet welded.Slip-on flanges are easy to use in fabricated applications. |
 ANSI ASME B16.5 lap joint flange drawing |
Lap joint flange(LJ flange) is always used with either a stub end or taft which is butt welded to the pipe with the flange loose behind it.This means the stub end or taft always makes the face.The lap joint is favoured in low pressure applications because it is easily assembled and aligned.To reduce cost these flanges can be supplied without a hub and/or in treated,coated carbon steel. |
 ANSI ASME B16.5 socket weld flange drawing |
Socket weld flange(SW 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 characteristics. |
 ANSI ASME B16.5 threaded flange drawing |
Threaded flange is referred to as either threaded or screwed.It is used to connect other threaded components in low pressure, non-critical applications.No welding is required. |
 ANSI ASME B16.5 ring type joint flange drawing |
Ring type joint is a method of ensuring leak proof flange connection at high pressures.A metal ring is compressed into a hexagonal groove on the face of the flange to make the seal.This jointing method can be employed on weld neck flanges,slip on flange and blind flanges. |
