PipingProjects.eu is a top source for Flange Weight Charts in kg, mm, and PDF. The weight of a Flange depends on its size, length, and material. The Flange weight chart shows these details in a table format.
Flanges have different properties depending on the type of stainless steel used to make them. They can be made by forging or casting. Companies that sell stainless steel flanges use them to connect pipes and columns in piping systems. The installation of these flanges is customized to fit the specific type of flange being used. The 2-inch and 4-inch stainless steel flat flanges have a simple flat face and are used in low-pressure situations. The PN16 stainless steel flanges are designed for higher-pressure systems with operating pressures up to 16 bar.
