2. Types of Flanges
Flange types
As already described before, the most used flange types ASME B16.5 are: Welding Neck, Slip On, Socket Weld, Lap Joint, Threaded and Blind flange. Below you will find a short description and definition of each type, completed with an detailed image.
Welding Neck flange
Welding Neck Flanges are easy to recognize at the long tapered hub, that goes gradually over to the wall thickness from a pipe or fitting.
This flange type will be welded to a pipe or fitting with a single full penetration, V weld (Buttweld).
DETAILS OF WELDING NECK FLANGE
1. Weld Neck flange 2. Butt Weld
3. Pipe or Fitting
Blind flange
Blind Flanges are manufactured without a bore and used to blank off the ends of piping, Valves and pressure vessel openings.
From the standpoint of internal pressure and bolt loading, blind flanges, particularly in the larger sizes, are the most highly stressed flange types.
However, most of these stresses are bending types near the center, and since there is no standard inside diameter, these flanges are suitable for higher pressure temperature applications.
DETAILS OF BLIND FLANGE

Dimensions are in inches. Weights are in pounds.
(1)- Bolt lenghts are calculated based on bolting one WN to one Blind.
(2)- Bolt diameter should be 1/8" less than the bolt hole diameter
Note:
Larger sizes as well as intermediate sizes can be furnished.
