Stainless Steel Flange is a type of pipe fitting that is used to connect two pipes or a pipe and a component, such as a valve or a pump, together. The flange is typically a circular plate with evenly spaced bolt holes around the circumference and a raised rim, or lip, around the edge. When the two flanges are bolted together, a seal is created between the two pipes or components. Stainless steel is a common material for flanges due to its high resistance to corrosion and durability.
