The high neck flange is also called the butt welding flange. It is different from the flat welding flange in that there is a long and inclined high neck from the flange and the pipe welding to the flange. The wall thickness of this section of the high neck Gradually transition to the thickness of the pipe wall along the height direction, which improves the discontinuity of stress and thus increases the strength of the flange.
High-neck flanges can be divided into flat high-neck flanges, raised-face high-neck flanges, concave-convex high-neck flanges, tongue-and-groove flanges, and ring-joint high-neck flanges.
