Nickle Alloy Flat Welding Flange Incoloy 925 Pharmaceutical Metallurgy Machinery
Nickle Alloy Flange, also known as a flange rim or flange, is a part that connects pipes to each other at the ends, and it is also used on equipment inlets and outlets for connecting two pieces of equipment, such as a reducer flange. A flange connection or flange joint refers to a detachable connection consisting of a flange, gasket, and bolt, which together form a combined sealing structure.
Welding Quality:
Many customers question whether the quality of welded steel plate flanges is superior to that of forged welded flanges. In reality, the quality of welded steel plate flanges is equivalent to that of forged welded flanges. However, what aspects of welded steel plate flanges cannot be guaranteed? That is, the material of welded steel plate flanges is the least secure, as during the general production process, the density of welded steel plate flanges is not an issue. But during the production process, the blanks of welded steel plate flanges are rarely inspected. Therefore, after production, the material of welded steel plate flanges that have not been inspected cannot be guaranteed.
