Intermediate Connection Flanges
Nozzle and reducing connection flanges for vessels and equipment
Intermediate connection flanges, also known as nozzle flanges or reducing flanges, are used to connect smaller-diameter piping to larger vessel nozzles or equipment connections. These flanges feature a bore that matches the smaller pipe size while maintaining the bolt pattern and outside diameter of the larger connection, eliminating the need for separate reducers at the vessel nozzle.
