stainless/carbon Flange

Flanges are parts that are connected to each other between pipes. The flanges have holes, and the bolts make the two flanges close. Gasket between flanges. Flanges include threaded connection flange, welding flange and clamp flange Flanges are used in pairs. Wire flanges can be used for low pressure piping and welded flanges can be used for pressure above 4 kg. Place a gasket between the two flanges and bolt them down Flange thickness of different pressure is different, they use different bolts. Pumps and valves, when connected to the pipe, the parts of these equipment are also made into the corresponding flange shape, also known as the flange connection.
