31603 Flat weld flange

31603 flat weld flange, also known as plate flat weld flange, is a kind of welded flange that is widely used in the connection of pipeline systems. The flange consists of a flat plate and internal and external threads, with the edges of the plate machined to form an arc shape to accommodate the welding of the pipe. Flat welded flanges have good sealing performance and structural stability, and are suitable for working conditions with low pressure levels and little temperature changes, and are widely used in petroleum, chemical, electric power and other industries.
