Reducing flange is a Special Flange used to connect two different diameters pipes in a piping system, commonly it is joint together with a regular standard flange. Welding neck flange is the correct terminology to be used as per Gost 12821-80,ASME B16.5 & B31.3. However in the industry Welding Neck Flanges are commonly refered to as Weld Neck Flange or WN flange. The welding neck flange consists of a tapered hub which is secured to the pipe by a full penetration butt weld. Because of the additional reinforcement area avaliable in the hub of weld neck flange and due to its installation by welding, the hub becomes an integral part of the pipe. This gives a weld neck flange greater strength and integrity and ability to withstand considerably higher bending moments than a slip on flange. Since weld neck flanges are secured to pipe by butt-welding, the internal diameter of the hub end should match the internal diameter of the pipe end. The details of matching pipe ID or wall thickness are required to be specified for purchasing weld neck flanges.
The industrial processes come into die forging,and machining,we can provide a wide range of flanges,following on standards like ASME B16.5 Flange , ASME B16.47 Flange, DIN 2573 Slip On Flange, DIN 2631 Welding Neck flange, JIS Flange 5K SOP Flange and JIS Flange 10K SOH Flange.
ASME Flange include ASME B16.5 Flange, ASME B16.47-A Flange, ASME B16.47-B Flange, this standard system include slip on flange, blind flange, welded neck flange, Threaded Flange, lapped joint flange (loose flange), socket welded flange, B16.36 Orifice Flange, long weld neck flange and special flange, sizes from 1/2 inch to 60 inch, class 150, class 300, class 600, class 900, class 1500, class 2500.
