90° long radius elbow
90 degree elbow is used to be installed between two lengths of pipe or tube allowing a change of 90 degree elbow long radius elbow,direction,usually these elbows distinguished by connection ends, The ends may be machined for butt welding , threaded , or socketed , so the elbows are consist of butt weld,thread elbow.socket elbow and other series.the material is selected accoding to the application use such as high temperature use,sanitary fitting,regular industrial use etc
