Size 1/8'' to 24'' Pressure 150LB, 300LB, 600LB, 900LB, 1500LB, 2500LB Connection Butt Weld & Socket Weld & Thread FlangesOur Flanges are drilled (machined) with the wall thickness of the flange having the same dimensions of the matching pipe. The lighter the pipe is, the larger the bore, conversely, the heavier the pipe, the small the bore. Our range weld neck flanges, welding neck flanges are normally used for high-pressure, cold or hot temperature. We specialize these flanges in different dimensional and material specifications based upon the requirements of the clients.Stainless Steel : ASTM A 182, A 240Grade : F 304, 304L, 304H, 316, 316L, 316Ti, 310, 310S, 321, 321H, 317, 347, 347H,904L, Duplex stainless steel UNS S31803, 2205, Super Duplex stainless steel UNS S32750 Carbon Steel : ASTM A 105, ASTM A 181Alloy Steel : ASTM A 182, GR F1, F11, F22, F5, F9, F91Nickel Alloys : Monel 400 & 500, Inconel 600 & 625, Incolloy 800, 825, Hastelloy C22,C276 Copper Alloys : Copper, Brass & GunmetalSize : 1/8" NB TO 48"NB.Class : 150#, 300#,400 #,600#,900#, 1500# & 2500 #.StandardANSI : 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, BS10
