What is a butt-weld flange? Butt-weld flanges include long-neck butt-weld flanges, necked butt-weld flanges, and butt-weld flanges, etc. It is mainly applicable to the butt welding of flanges and pipes. It has high strength and rigidity, a reasonable structure, and can withstand high temperature, high pressure, repeated bending and temperature fluctuations. Moreover, its sealing performance is reliable. The butt welding flange adopts a concave-convex sealing surface and nominal pressure0.25~2.5MPa.

　　Generally speaking, butt-weld flanges are a type of flange pipe fittings. They are flanges that are butt-welded to pipes and have a neck with a circular pipe transition. They are widely used and promoted in various fields and industries, and their application scope and usage environment also need to be used under certain conditions.

　　The nominal pressure of butt-weld flanges must be maintained within a certain range during use. They play an important role and have significant value in pipeline connections and are suitable for situations where the nominal pressure does not exceed2.5MPaThe connection of steel pipes. Flange butt-weld sealing surfaces can be classified into three types: smooth type, concave-convex type and tenon and groove type. Smooth butt-weld flanges are widely used and are often employed in conditions with mild media, such as low-pressure circulating water and low-pressure unpurified compressed air. One of its advantages is its low cost. Butt-weld flanges are suitable for high-temperature, high-pressure, low-temperature pipelines or pipelines with large fluctuations in temperature or pressure, and also for pipelines transporting expensive flammable and explosive media.

　　At present, butt-weld flanges are widely used and promoted in pipe fittings. Due to the differences in their application environments and scopes, the use of butt-weld flanges needs to be carried out in accordance with the corresponding methods.

　　The forging process of butt-weld flanges generally includes several steps such as selecting high-quality billets for blanking, heating, forming, and cooling after forging. The forging processes include die forging, die mold forging, and free forging. During production, different casting methods are selected based on the quality of the forgings and the production batch.

　　The above is today's sharing about the forging process of butt-weld flanges. We hope that through the above sharing, everyone can have a deeper understanding of flanges and butt-weld flanges, so that they can deal with such problems calmly in future life.
