ANSI/ ASME B16.5 class 1500 slip on flange

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 standard covers pressure,temperature,ratings,materials,dimensions, tolerances,marking,testing,and methods of designating openings for pipe flanges and flanged fittings.Slip on flange dimensions are covered in ANSI/ASME B16.5 class 1500 for size NPS ½” to 2 ½”.

Types of ANSI/ASME B16.5 forged flanges:

ANSI ASME B16.5 weld neck flange drawing

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

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

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

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

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

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

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.
