Hot Sale Welding Neck Titanium Flange Wn Flanges

Welding Neck FlangesWeld neck flange (WN flange) has a neck that can relocated stress of the pipe, so to reduce the pressure that gathered in the flange bottom.Material: Carbon, Alloy and Stainless SteelStandards: ASTM A105, ASTM A182Sizes: 1/2'' to 24'', Customized up to 48''Thickness: Schedule 10(S) to SCH 160Pressure Ratings: Class 150 to 2500Face Type: RF, RTJThe Welding neck flanges is normally referred to as the high hub flange. It is designed to transfer stresses to the pipe, thereby reducing high stress concentrations at the base of the flange.It is compatible to the pipelines that works in high or low temperature and bear high pressure. Specially for the pipe or the valves when PN is larger than 2.5 Mpa.Two Shapes of Welding Neck FlangeWelding neck flange have two forms (shapes), one with reducing neck as we called reducing weld neck flange; One with a even diameter of typical long neck named as long neck weld flange.Reducing Weld Neck Flange                                                                                                 As it's name it is like a combination of pipe reducer and flange, so it could be welded to a smaller pipe directly.Long Weld Neck FlangeSimplified called as LWN flange, the neck part seems like a elongated pipe and connected to a flange. So in most cases it works as a nozzle for a column or a barrel.You can choose for a normal thickness long welding neck flange or a heavy LWN flange that with bigger thickness and a differently shape.Face TypeLike other flanges it has Raised Face (RF) Type and Ring Type Joint (RTJ).Raised Face Weld Neck FlangeRTJ Weld Neck FlangeStandards Referred for WN flangeMaterial StandardsASTM A105/N For carbon steel weld neck flangeASTM A182 F11, F22 for alloy steelASTM A182 F304 / F304L, F316 / F316L for stainless steel weld neck flange.Manufacturing StandardsASME B16.5ASME B16.47BS 3293DIN 2630 PN 1 and PN 2.5, 2631 PN 6, 2632 PN 10, 2634 PN 16, 2634 PN 25, 2635 PN 40Weld neck flange datasheetsClassFlat FaceRaised FaceRing Type JointANSI 150WN Flange ANSI 150 FF (in)WN Flange ANSI 150 RF (in)WN Flange ANSI 150 RTJ (in)ANSI 300WN Flange ANSI 300 FF (in)WN Flange ANSI 300 RF (in)WN Flange ANSI 300 RTJ (in)ANSI 400WN Flange ANSI 400 FF (in)WN Flange ANSI 400 RF (in)WN Flange ANSI 400 RTJ (in)ANSI 600WN Flange ANSI 600 FF (in)WN Flange ANSI 600 RF (in)WN Flange ANSI 600 RTJ (in)ANSI 900WN Flange ANSI 900 FF (in)WN Flange ANSI 900 RF (in)WN Flange ANSI 900 RTJ (in)ANSI 1500WN Flange ANSI 1500 FF (in)WN Flange ANSI 1500 RF (in)WN Flange ANSI 1500 RTJ (in)ANSI 2500WN Flange ANSI 2500 FF (in)WN Flange ANSI 2500 RF (in)WN Flange ANSI 2500 RTJ (in)The datasheets we have on this site are shown below. For simplicity sake, only datasheets that adhere to B16.5 are shown. ASME B16.5 covers flange dimensions from ½" to 24". For sizes larger than this, please visit our flange datasheets page.Types of facings in weld neck flangesThe three most common types of facings for weld neck flanges are:Raised face (most common)Ring type joint (RTJ)Flat faceKey FeaturesThis 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.How to measure weld neck flange?Take the measurements of the following:A: Hub Diameter at Point of WeldB: Weld Neck BoreC: ThicknessY: Length through HubO: Outside DiameterR: OD of Raised FaceX: Diameter at Base of HubMaterialsPipe flanges are manufactured in all the different materials like stainless steel, cast iron, aluminium, brass, bronze, plastic etc. but the most used material is forged carbon steel and have machined surfaces.Flanges are welded to pipe and equipment nozzle. Accordingly, it is manufactured from the following materials;Carbon steelLow alloy steelStainless steelCombination of Exotic materials (Stub) and other backing materialsThe list of materials used in manufacturing is covered in ASME B16.5 & B16.47.ASME B16.5 -Pipe Flanges and Flanged Fittings NPS ½" to 24"ASME B16.47 -Large Diameter Steel Flanges NPS 26" to 60"Commonly used Forged material grads areCarbon Steel: - ASTM A105, ASTM A350 LF1/2, ASTM A181Alloy Steel: - ASTM A182F1 /F2 /F5 /F7 /F9 /F11 /F12 /F22Stainless Steel: - ASTM A182F6 /F304 /F304L /F316 /F316L/ F321/F347/F348Frequently used astm gradesMaterialFittingsFlangesValvesBolts & NutsCarbon SteelA234 Gr WPAA105A216 Gr WCBA193 Gr B7A194 Gr 2HA234 Gr WPBA105A216 Gr WCBA234 Gr WPCA105A216 Gr WCBCarbon SteelAlloyHigh-TempA234 Gr WP1A182 Gr F1A217 Gr WC1A193 Gr B7A194 Gr 2HA234 Gr WP11A182 Gr F11A217 Gr WC6A234 Gr WP12A182 Gr F12A217 Gr WC6A234 Gr WP22A182 Gr F22A217 Gr WC9A234 Gr WP5A182 Gr F5A217 Gr C5A234 Gr WP9A182 Gr F9A217 Gr C12Carbon SteelAlloy Low-TempA420 Gr WPL6A350 Gr LF2A352 Gr LCBA320 Gr L7A194 Gr 7A42
