Specification :

Steel elbow is used to be installed between two lengths of pipe or tube allowing a change of direction, usually these carbon steel elbows distinguished by connection ends, The ends may be machined for butt welding , threaded , or socketed , so the carbon steel elbows are consist of butt weld, thread elbow socket elbow and other series.the material is selected according to the application use such as high temperature use, sanitary fitting, regular industrial use etc.
Note: L/ R - Long radius, S/ R - Short radius
