Stainless Steel ElbowStainless steel elbow is usually installed between two lengths of stainless steel pipe(or tubing) to allow a change of direction,Website:http://www.syemetal.com, usually a 180º, 90º, or 45º angle. 22.5ºstainless steel elbows are also available. The end of stainless steel elbow may be machined for butt welding, threaded (usually female) or socket. When the ends differ in size, it is known as a reducing (or a reducer) elbow. Stainless steel elbows are categorized by design. The radius of a long-radius (LR) elbow is 1.5 times the pipe diameter. In a short-radius (SR) elbow, the radius equals the pipe diameter. Ninety-, 60- and 45-degree elbows are also available. Most stainless steel elbows are available in short- or long-radius versions. Short SS elbow, widely available, are typically used in pressurized systems. Long stainless steel elbows are used in low-pressure gravity-fed systems. Jiangsu Sheye Metal is a professional manufacturer specialized in manufacturing stainless steel elbow. According to different production process, stainless steel elbows can be divided into two types: seamless stainless steel elbows and welded stainless steel elbow. There are main four types elbows like: 45º Stainless Steel Elbow,90º SR Stainless Steel Elbow(Short Radius),90º LR Stainless Steel Elbow(Length Radius),180º Stainless Steel Elbow. The outside diameter of stainless steel elbows we produce ranges from 4.0 mm to 1219mm. The wall thickness is 0.5mm to 40mm. For metal, we are serious.45º Stainless Steel Elbow Size OD: seamless DN15-DN600; Welded DN15-DN1200; WT:SCH5S-SCH160;Process Mandrel formingSurface Aid Pickling, Polishing, Shot Blasted, Rolling Sand90º LR Stainless Steel Elbow(Length Radius) Size OD: seamless DN15-DN600; Welded DN15-DN1200; WT:SCH5S-SCH160;Process Mandrel formingSurface Aid Pickling, Polishing, Shot Blasted, Rolling SandNote: Long radius elbow refers to its radius of curvature is equal to 1.5 times the diameter of the pipe, R＝1.5D90º SR Stainless Steel Elbow(Short Radius) Size OD: seamless DN15-DN600; Welded DN15-DN1200; WT:SCH5S-SCH160;Process Mandrel formingSurface Aid Pickling, Polishing, Shot Blasted, Rolling SandNote: Short radius elbow refers to its radius of curvature is equal to 1 times the diameter of the pipe, R＝1D180º Stainless Steel Elbow Size OD: seamless DN15-DN300; Welded DN15-DN300; WT:SCH5S-SCH160;Process Ball forming/Hot formingSurface Aid Pickling, Polishing, Shot Blasted, Rolling SandMain Grades of Stainless Steel Seamless PipeAustenitic/Super Austenitic Stainless Steel Seamless Pipe 304, 304H, 304L, 304LN, 321, 321H, 316, 316L, 316LN, 316Ti, 317L, 310S, 310H, 314, 347H, 904L, S31254, N08367, N08926, S32654, S31277 Ferrite/Super Ferrite Stainless Steel Seamless Pipe 405, 430, 439, 444, TP446-1/TP446-2, S44660, S44735, S44736 Duplex/Super Duplex Stainless Steel Seamless Pipe S31500, S31803, S32205, S32304, S32520, S32550, S32750, S32760 Martensite/Super Martensite Stainless Steel Seamless Pipe 410S, 410, 420, 420J2, 431, 17-4PH, 13Cr110, 17Cr110/125 Nickel Alloy Seamless Pipe N04400, N05500, N06600, N06601, N06025, N06617, N06625, N06690, N08810, N10276, N06022, N10665, N10675, N08020, N08028, N08031, N06985, N06030, N06035, N07750Production Standard of Stainless Steel ElbowGB GB/T 12459, GB/T 13401, GB/T 14975 ASTM ASTM B16.9 SH SH 3408, SH3409 HG HG/T 21635, HG/T 21631 SY SY/T 05010Tolerance in butt-welding fittings(ASTM/AISI B16.9、B16.28) of Stainless Steel Elbows Specifications Types Nominal diameter 1/2-21/2 3-31/2 4 5-8 10-18 20-24 26-30 32-48 Outside Diameter All Pipe Fittings +1.52±1.52+2.29+4.06+6.35-0.76--1.52-3.05-4.83Inside Diameter All Pipe Fittings±0.76-±3.05±4.83Wall Thickness All Pipe Fittings≥0.875*WTCenter to End 45º/90º Elbows±1.52±2.29±3.05+4.83Center to center 180° Elbows±6.35±9.65-Back to face 180° Elbows±6.35-U 180° Elbows±0.76±1.52-Packing Information of Stainless Steel ElbowsStainless steel elbows from Sheye Metal are packed and labeled according to the regulations and customer's requests.
