Expander Flange by Pipe Fitting Suppliers is a Welding Neck pipe flange where the nominal size of the non-flanged end is bigger than the nominal size of the flanged end. These flanges can also be customized and designed to fit in any pipe solution requirement. This is also an alternative for the use of separate reducer and weld neck flange combination. These expander flanges can be also used to connect pipe to pumps, compressors and other valves
The specification include for better productivity with size 1/2" NB TO 48"NB. Each of these products have an excellent class type which is named or numbered as 150#, 300#, 400 #, 600#, 900#, 1500# & 2500 #. The standards for stainless steel are named as ASTM A 182, A 240 with other materials like Carbon Steel : ASTM A 105, ASTM A 350, Alloy Steel : ASTM A 182, GR F1, F11, F22, F5, F9, F91, Nickel Alloys : Monel 400 & 500, Inconel 600 & 625, Incolloy 800, 825, Hastelloy C22,C276,Cupro Nickel, Alloy 20. All these are also graded according to the material and standards which include F 304, 304L, 304H, 316, 316L, 316Ti, 310, 310S, 321, 321H, 317, 347, 347H, 904L, duplex stainless steel UNS S31803, 2205, and 2507. These expander flanges are also beneficial for its compact size space when compared to other type of flange called reducer-welded neck flange. To too add too many additionals only one butt-weld is needed to install the expander flange which is very costly and very effective with best competitive price.
