ASTM A234 WPB B16.9 S/R Carbon Steel Butt Welding 90 Degree Short Radius Elbow
Carbon Steel Pipe Fittings Elbow could be a most common sort of CS fitting utilized to connect pipe or tubing to permit a alter of direction, more often than not a 90° or 45° angle, though 22.5 Degree Elbow Carbon Steel is additionally utilized in a piping framework. Carbon steel elbows are metal fittings that change the direction of the pipe on the carbon steel pipe. Connections are threaded and welded. Divided by angle, there are 45 ° and 90 ° 180 ° the three most commonly used, in addition to other engineering needs also include 60 ° and other abnormal angle elbow. Elbow materials are cast iron, stainless steel, alloy steel, malleable iron, carbon steel, non-ferrous metals and plastics. The connections to the tube are: direct welding (the most common method) flange connection, hot melt connection, electrofusion connection, screw connection and socket connection. According to the production process can be divided into: welding elbow, stamping elbow, pushing elbow, casting elbow and so on. Carbon steel elbow is a kind of carbon steel pipe fittings.

Carbon steel elbow is first divided into its radius of curvature, which can be divided into long radius elbows and short radius elbows. The long-radius elbow refers to its radius of curvature equal to 1.5 times the outer diameter of the tube, ie R = 1.5D. A short-radius elbow means that its radius of curvature is equal to the outer diameter of the tube, ie R = 1.0D. (D is the diameter of the elbow, and R is the radius of curvature. D can also be expressed in terms of folds.) If there are 17 levels depending on the pressure rating, the same standards as in the U.S. tube are: Sch5s, Sch10s, Sch10 , Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, Sch100, Sch120, Sch140, Sch160, XXS, the most commonly used are STD and XS. According to the angle of the elbow, there are 45° elbows, 90° elbows and 180° elbows.

ASME B16.9 S/R Elbow Dimensions

The standard short-radius(S/R) elbows of ASME B16.9 are generally furnished in 90°. It makes a much sharper turn than does the long radius elbows. The center-to-end dimension is 1D radius which equals to 1 x NPS in inch unit. Conversely, the S/R elbow creates a rather large pressure drop inside the line and does not have the smooth flow characteristics the L/R elbow has.

Dimensions

*NPS: Nominal Pipe Size; O.D: Outside Diameter at Bevel; A: Center-to- End.

ASTM A234 WPB Chemical Compositions (%)

*For ASTM A234 Gr. WPB, the carbon equivalent (C.E.), based on heat analysis and the following formula, shall be no greater than 0.50. C.E. = C + Mn / 6 + (Cr + Mo + V) / 5 + (Ni + Cu) / 15. The C.E. values shall be reported on the test report.
*ASTM A234 WPB fittings made from bar or plate may have 0.35 max carbon and that made from forgings may have 0.35 max carbon and 0.35 max silicon with no minimum.
*For each reduction of 0.01% below the specified carbon maximum, an increase of 0.06% manganese above the specified maximum will be permitted, up to a maximum of 1.65%.
*The sum of copper, nickel, chromium, and molybdenum shall not exceed 1.00%
