If their sizes differ, the stainless steel pipe fitting is know as a reducing coupling, reducer or adapter. There are two types of couplings: slip and regular. Stainless steel couplings are highly demanded in the stainless pipe fitting market. Stainless steel couplings always help to extend or terminate pipe runs. SS couplings extend a run by jointing two lengths of pipe. Stainless steel coupling, also known as repair couplings, is without stops or ridges and they can be fixed anywhere along the pipe length for preventing leak of any kind.Stainless Steel UnionA stainless steel union, similar to stainless steel coupling, allows the convenient disconnection of pipes for maintenance or fixture replacement. Although a SS coupling requires solvent welded, soldering or rotation, a stainless union allows easy connection and disconnection. It consists of three parts: a nut, a female end and a male end. When female and male ends are joined, the nut seals the joint. Stainless steel unions are a type of flange connector.Stainless Steel NippleStainless steel nipple is a pipe fitting, consisting of a short piece of pipe, usually provided with a male pipe thread at each end, for connecting two other fittings. The length of stainless steel nipple is usually specified by the overall length with threads. It may have a hexagonal section in the center for wrench to grasp, or it may simply be made from a short piece of pipe. When the ends are of two different sizes it is called a reducer or unequal nipple.Stainless Steel Coupling, Union Size 1/8" to 4" (DN6– DN100)Pressure 2000LBS, 3000LBS, 6000LBS, 9000LBSStandard ANSI B16.9/B16.28 and MSS SP-43/SP-75Ends Butt Welded, ThreadedThread Types NU, EU, STC, LTC, BTCSurface Shot Blasted, Rolling Sand, PolishingStainless Steel Nipple Size 1/8" to 12" (DN6– DN200)Type TBE, TOE POE, PBEStainless Steel Coupling    Nominal Diameter    The Length of Coupling and Cap Outside Diameter End Wall Thickness Length of Thread E F D C min  DN NPS 3000LB 6000LB 3000LB 6000LB 3000LB 6000LB 3000LB 6000LB B L2   Sch160 XXS Sch160 XXS Sch160 XXS Sch160 XXS   61/8323219-16225.0-6.56.581/43535252719255.06.58.010.0103/83838252722325.06.59.010.5151/24848323329386.58.011.013.5203/45151373835446.58.012.514.02516060414344579.511.014.517.5321.1/46767444657649.511.017.018.0401.1/276764448647611.012.518.018.550286864851769212.516.019.019.0652.1/2929260649210816.019.023.529.0803108108656810812719.022.026.030.51004121121687514015922.028.527.533.0Note: The above size comply with ANSI B16.11, BSP3799, GB/T14626Stainless Steel Union Nominal Diameter Outside Diameter Wall Thickness Socket Bore Water way Bore Depth of Socket Length Assem      Nominal D min C min d1 d2 J min L DN NPS Socket Threaded Socket Threaded Socket Socket & Threaded Socket Socket & Threaded 61/821.814.73.22.510.656.431041.481/421.8193.33.114.19.451041.4103/825.922.93.53.217.5513.511046151/231.227.74.13.821.717.071049203/437.133.54.3427.0521.391356.925145.541.454.633.827.741362321-1/454.950.55.34.942.5535.361371.1401-1/261.557.25.65.148.6541.21376.550275.270.16.15.661.152.121686.1652-1/291.785.37.77.173.864.3116102.4803109.2102.48.47.789.877.2716109Note: The above size comply with MSS SP-83, BS3799.Stainless Steel Nipple (Inch Pipe) Nominal Size Outside Diameter Sch40/STD    Sch80/XS Sch160    XXS L(mm) DN NPS     81/413.5Ο 100      150      200103/817.2Ο  151/221.3ΟΟ 203/426.7ΟΟ 25133.4ΟΟ 3211/442.2ΟΟ 4011/248.3ΟΟ 50260.3ΟΟMain Grades of Stainless Steel Coupling Union Nipple Austenitic/Super Austenitic Stainless Steel Caps 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 Caps 405,  430,  439,  444,  TP446-1/TP446-2,  S44660,  S44735,  S44736 Duplex/Super Duplex Stainless Steel Caps S31500,  S31803,  S32205,  S32304,  S32520, S32550,  S32750,  S32760 Martensite/Super Stainless Steel Caps  410S,  410,  420,  420J2,  431,  17-4PH,  13Cr110,  17Cr110/125 Nickel Alloy Caps N04400,  N05500,  N06600,  N06601,  N06025,  N06617,  N06625,  N06690,  N08810,  N10276,  N06022,  N10665,  N10675,  N08020,  N08028,  N08031,  N06985,  N06030,  N06035,  N07750Packing Information of Stainless Steel Coupling Union Nipple Stainless steel coupling union nipple from Sheye Metal are packed and labeled according to the regulations and customer's requests.
