Elbow, the same size used in connection withthe different angles of the tubes. By the resistance,long radius elbow (also known as 1.5 times theelbow) and the short radius elbow (also knownas double elbow), according to the angle, forthe 90-degree bend, bend 45 degrees, 180 degreeselbow , Elbow 60 degrees, 120 degrees elbow,and so on. 

Short radius bend radius of short and longradius bend radius of long and short radiuselbow medium flow resistance, resistance toa smaller bend radius long. 

My company is located in Mengcun, mainly theproduction of carbon steel, alloy steel, stainlesssteel seamless, high-pressure, pressure, lowdouble-thick wall (long radius), 1 times (shortradius), 90 D, 45D, 180D, 60D elbow. 

International code: ELBOW L / R-radius elbow,ELBOW S / R short radius elbow.
