ANSI B16.9 A234 WPB Short Radius Elbow 

We are a manufacture of steel pipe fittings , we can produce kinds of Elbow  Pipe Fitting,  Pipe Fitting Eccentric Reducer,  Pipe Cap,  Steel Reducing Tee ,  Carbon Steel Flange and so on .the Elbow Pipe Fitting is including 180 Degree  Pipe Elbow,  90 Degree Elbow ,45 Degree Pipe Elbow . Elbow by its radius of curvature to points, can be divided into long radius elbow and short radius elbow. A long-radius elbow refers to a tube having a radius of curvature equal to 1.5 times the outer diameter of the tube, i.e. R = 1.5D. A short-radius elbow means that its radius of curvature is equal to the outside diameter of the tube, ie, R = D. Where D is the elbow diameter and R is the radius of curvature. Normal selection of the length of the radius Sometimes to reduce the loss of resistance or elbow wear, will use a larger bend radius of the elbow (in fact, has not called the elbow); in the installation of limited time will use a short ra…
