| welding neck Flange | A welding neck Flange is similar to slip on flanges,however, socket welds have |
| an internal recess on the inside diameter to allow for a smoother flow of the | |
| process fluid. The positive of this is that is creates a smooth bore with the | |
| proper welding and grinding. The negative of this type of flange is that it can | |
| be more expensive than a slip-on due to more intricate machining, and they can be less readily available than slip-ons due to the fact that the | |
| bottom half of the inside diameter must be made to the same schedule as the pipe that is being used (you must specify the schedule needed) | |
| These socket weld flanges were initially developed for use on smaller sizes | |
| of pipe at higher pressure ratings. | |
