Carbon steel elbow - carbon steel elbow definition:

Carbon steel pipe elbow is to change the direction of the metal pipe fittings

Carbon steel elbow - carbon steel elbow Category:

Divided by the angle: 45 °, 90 °, 180 ° bend these three common, another project needs, such as 60 ° may be particularly customized like.

And carbon steel pipe are linked: weld, flanged, threaded, socket links to other forms.

Process can be divided according to the form: welding elbow, pressing elbow, casting elbow.

Carbon steel elbow English (Carbon steel elbow) first by its radius of curvature to points, can be divided into long radius elbows and short radius elbows. Long radius elbow refers to its radius of curvature is equal to 1.5 times the pipe diameter, i.e. R = 1.5D.

Short radius elbow refers to its radius of curvature equal to the pipe diameter, ie R = 1.0D. (D is the bend diameter, R is the radius of curvature .D can also be used to represent the times.) If the pressing force rating points, about seventeen kinds, and U.S. standard pipes are the same, there are: Sch5s, Sch10s, Sch10 , Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, Sch100, Sch120, Sch140, Sch160, XXS, which is the most common STD and XS two kinds. According to the angle of bend points, 45 ° elbow, there are 90 ° and 180 ° elbow bend.

Implementation of standards GB / T12459-2005, GB / T13401-2005, GB / T10752-1995, HG / T21635-1987, D-GD0219 and so on.
