Weld Neck Flanges have a long tapered hub and are often used for high pressure applications. When ordering a weld neck flange, it is important to specify the schedule pipe is being used for.
his is because the inside diameter of the flange will match the inside diameter of your pipe. The buttweld joint this flange has with the pipe along with the tapered hub, makes this flange very resistant to dishing and a very sturdy connection. These flanges are ideal for extreme fluctuations of temperature and in environments where there may be a lot of bending and handling of the flanges.ProductStainless steel Weld Neck FlangeMaterial GradeF304, 304L, 304H, 316, 316L, 316Ti, 310, 310S, 321, 321H, 317, 347, 347H,904L, Duplex stainless steel UNS S31803, 2205, Super Duplex stainless steel UNS S32750CertificationISO9001:2016, TSStandardANSI :ANSI B16.5, ANSI B16.47, MSS SP44, ANSI B16.36, ANSI B16.48DIN :DIN2527, DIN2566, DIN2573, DIN2576, DIN2641, DIN2642, DIN2655, DIN2656, DIN2627, DIN2628, DIN2629, DIN 2631, DIN2632, DIN2633, DIN2634, DIN2635, DIN2636, DIN2637, DIN2638, DIN2673B.S :BS4504 , BS4504, BS1560, BS10Size10-2000Pressure150#, 300#,400 #,600#,900#, 1500# & 2500 #.TypeWNFlange surfaceFF, RF,MFM,TG,RJStainless SteelASTM A182 F304,F304L,F316,F316L,1cr18Ni9Ti,0cr18Ni9Ti,321,18-8
