ANSI B16.9 Carbon Steel 6 Inches Elbow

45 degree carbon steel elbow is first divided according to its radius of curvature, can be divided into long radius elbow and short radius elbow. Long-radius elbow refers to its radius of curvature equal to 1.5 times the outer diameter of the tube, that is, R = 1.5 D. Short-radius elbow refers to its radius of curvature equal to the outer diameter of the tube, that is, R = 1.0 D. (D is the elbow diameter, R is the radius of curvature. D can also be expressed in times.) If divided by pressure class, there are about seventeen types, which are the same as the US pipe standards, namely: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, Sch100, Sch120, Sch140, Sch160 XXS, of which the two most commonly used are STD and XS. The executive standards are GB/T12459-2005, GB/T13401-2005, GB/T10752-1995, HG/T21635-1987, D-GD0219, etc. The advantages of the carbon steel elbow production process are mainly manifested in the following aspects. (1) do not need b…
