Royal Steel

Stainless Steel Plate Flange is a type of flange that consists of a flat, circular plate with evenly spaced bolt holes for connecting it to another flange or equipment. It does not have a raised hub like some other types of flanges. The plate flange is typically used in applications where welding is not practical or necessary. ASME B16.5 Plate Flange has all the chemical and mechanical properties that make the product to work smoothly. It is the one where unique dimensions, weights and other specifications are provided. It is designed in the form of a plate or ring which connects two pipes and the parts of bolted together.
