Introduction to the use and production of large flanges
Common integral flanges include flat welding flanges and butt welding flanges. Large flanges have poor rigidity and are suitable for occasions with pressure p ≤ 4MPa; large flanges, also known as high neck flanges, have high rigidity and are suitable for occasions with high pressure and temperature.

The flanges are gasketed. American standard flanges can be cast or threaded or welded.
This process is suitable for the production of large flanges of any specification where the ratio of the medium diameter of the stamping flange to the inner diameter of the stamping flange is greater than 1.5. Now, we produce stamping flanges and butt welding flanges. Flange flange products such as push flanges, butt welding flanges, and flat welding flanges are deeply trusted by customers. We will weld polygonal annular shells with polygonal cross-sections or polygonal sector shells with closed ends. When the pressure medium is filled with internal pressure, the section gradually changes from polygon to circle under the effect of internal pressure, and finally a circular annular shell is formed.

The fatigue strength of socket welded joints is lower than that of butt welded joints due to fillet welds and steep changes in geometry. However, socket welded joints are still superior to other mechanical connections.
