ASME B16.5 Loose Flange/Lap Joint Flange Dimensions
Lap Joint Flanges have all the same common dimensions as any other flange named on this page however it does not have a raised face, they used in conjunction with a “Lap Joint Stub End”. These flanges are nearly identical to a Slip On flange with the exception of a radius at the intersection of […]
ASME B16.5 Long Weld Neck Flange/Intergal Flange Dimensions
Long Neck Welding (abbreviated LWN) flanges are similar to a standard Welding Neck flange, but the “Neck” is considerably longer. This type is often used as a nozzle for a barrel or column. In addition, there are the type LWN Heavy Barrel (HB) and the Equal LWN Barrel (E); they have a different shape and […]
ASME B16.5 Blind Flange/Blank Flange Dimensions
A blind flange is a solid disk used to block off a pipeline or to create a stop. It is machined in the same manner as a regular flange with the mounting holes around the perimeter and the gasket sealing rings machined into the mating surface. The difference is that a blind flange has no […]
ASME B16.48 Spectacle Flange/Spectacle Blind/Paddle Flange/Spades Spacers Dimensions
ASME B16.48 Spectacle Flanges Dimensions A spectacle blind is a safety device used to isolate a section of line or piece of equipment when the line or equipment needs to be inspected or removed from service. It is different than a valve in that the blind is a permanent or long term isolation device. A […]
ASME B16.47 Series B Weld Neck Flange/WN Flange Dimensions
Weld neck flange (also known as a high-hub flange and tapered hub flange) is a type of flange. There are two designs. The regular type is used with pipes. The long type is unsuitable for pipes and is used in process plant.A weld neck flange consists of a circular fitting with a protruding rim around the circumference. Generally machined […]
DN15 JIS B2220 5K 4Inch A182 F5 Slip On Plate Flange
The JIS B2220 5K slip on plate flange is fillet welded with the pipe or fitting,different with the butt welding method of weld neck flange,and the pipe no need to do the bevel end,just square end is for welding.Commonly,the JIS B2220 5K slip on plate flange can be fillet welded with the pipe on the two sides.JIS B2220 […]

ASME B16.47 Series A Slip On Flange/SO Flange Dimensions
ASME B16.47 Series A Slip On Flange Dimensions The calculated strength from a Slip On flange under internal pressure is of the order of two-thirds that of Welding Neck flanges, and their life under fatigue is about one-third that of the latter. The connection with the pipe is done with 2 fillet welds, as well at the outside […]
