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.

In high-pressure equipment and pipelines, metal gaskets of lens type or other shapes made of copper, aluminum, No. 10 steel, and stainless steel are used. The contact width between the high-pressure gasket and the sealing surface is very narrow (line contact), and the processing finish between the sealing surface and the gasket is high.

Under the effect of internal pressure, it gradually changes from a polygon to a circle, and finally forms a circular annular shell

The large flange connection is a detachable connection. According to the connected parts, it can be divided into container flanges and pipe flanges

The contact width between the high-pressure gasket and the sealing surface is very narrow (line contact), and the processing finish between the sealing surface and the gasket is high.

Talking about the processing flow and performance characteristics of high pressure flanges

The processing methods of high-pressure flanges are messy. It is necessary to pay attention to the characteristics and specifications related to them during the processing process to avoid diverging the processed high-pressure flange. American standard flanges are parts that connect the pipe and the pipe to each other and connect to the end of the pipe. American standard flanges have holes, and bolts make the two flanges tightly connected.
