  Weld neck flanges is composed of a flange with an inner hole in the center of the flange and a plurality of screw holes on the flange. One side of the flange is provided with a neck-shaped protrusion. The inner diameter of the neck-shaped protrusion is equal to and connected with the inner diameter of the inner hole. On the other side of the flange is provided with a circular depression, the center of the circular depression coincides with the central axis of the inner hole, and the radius ratio of the circular depression to the inner hole. Large radius, there is also a circular depression in the circular depression. The center of the circular depression coincides with the central axis of the inner hole, and the outer surface of the circular depression coincides with the outer surface of the circular depression.

  Weld neck flanges advantages: ASTM A182 Sch20 Stainless Steel Weld Neck Flange with neck belongs to flat-welded flange, because it has a short neck, which improves the strength of flange and improves the bearing capacity of flange. So it can be used in pipelines with higher pressure.

  Weld neck flanges disadvantage: Weld neck flanges compared with plate flange, it is more expensive and easier to bump in transportation because of its shape characteristics.
