Flat Face Flange

Marine flanges are flanges used on ships, and flanges are parts that connect pipes to pipes. connected to the pipe end. There are holes on the flange, and bolts can be worn to make the two flanges tightly connected. The flanges are sealed with gaskets.

Flange connection is to fix two pipes, pipe fittings or equipment on a flange plate respectively, add flange pads between the two flange plates, and fasten them together with bolts to complete the connection. Some pipe fittings and equipment have their own flanges, which are also flange connections.
