ASME B16.9 90 Degree Elbow Weight list,How to calculate the Weight for a 90deg eblow
A 90° elbow is a pipe fitting used to change the direction of flow by 90 degrees in a piping system. It is one of the most commonly used pipe fittings.
Weight is very important information for people to know for the fittings handle and transportation purpoe,
Here we would like to introduce the weight of the 90de Elbows.
As most if the Butt weld elbows are produced according to ASME B16.9 standard.
We may easily find the weight chart list for standard elbow as below

How to calculate the Weight for a 90deg eblow?
Approximate weight of a butt welding elbow can be calculated based on its its radius, wall thickness and angle. Please note that actual weight of a elbow from a particular manufacturer may vary depending on manufacturing process. Dimensional standards like ASME B16.9 do not provide weights of butt welding fittings.
The weight formula is W=0.0387 * S*(D – S) * R / 1000, the result will come out with kg/piece.
- W means Weight.
- S means Thickness in mm.
- D means Outside Diameter in mm.
- R means Radius that LR=1.5D, SR=1D.
For example,we want to calculate the weight for “90 Degree Elbow LR Seamless 6″ Sch 40 BW ASTM A234 WPB”
We use the above forumla,we know the outside diameter is 168.3mm and thickness is 7.11mm. The weight will be 0.0387 x 7.11 x ( 168.3 – 7.11 ）x 1.5 x 168.3 / 1000 = 11kg/piece.
