Long welding neck flange is the neck height higher, which improves the rigidity and bearing capacity of the flange. Compared with butt welding flanges, the welding workload is large, the welding rod consumption is high, and it cannot withstand high temperature and pressure, repeated bending and temperature fluctuatuins, but it is more convenient for onsite installation and can omit the process of welding seam scratching, which is more popular. Long welding neck flange is similar to a standard Welding Neck Flanges, but the neck is considerably longer than other flanges. LWN flange is often used as a nozzle for a barrel or column. This is the most common type of high pressure pipe flange. They are distinguished from other types of pipe flanges by their long tapered hub and gentle transition of thickness in the region of the butt weld joining them to the pipe. The long tapered hub provides an important reinforcement of the Weld Neck Flange proper in terms of strength and resistance to dishing. Use of WN flanges: LWN is very resistant to dishing and has a very sturdy connection because it has the pipe along with the tapered hub. The flanges are ideal for extreme fluctions of temperature. They are ideal in enviroments where there maybe a lot of bending and handling of the flanges. Preferred in enviroment with extreme temperature conditions. This type of flange is preferred for every serve service condition resulting from high pressure or from sub-zero or elevated temperature. They are used in situations where loading conditions are substantially constant or fluctuate between wide limits. This is probably the best welding flange available because of its high, heavy neck. Highly recommended wherever a sound welded joint connection is needed.
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.
