Flanges are components used to connect pipes and other equipment in a piping system. They provide a method for assembling or disassembling piping systems for maintenance, repair, or inspection. Flanges are usually round with bolt holes at the edges. Flange cover is a protective device designed to cover and protect the exposed surface of a flange. When flanges are not in use or during transportation and storage, they help prevent damage, corrosion, dust and contamination.Flange Canopies
