Why Calculate the Weight of the Elbow

In order to enable customers to choose a suitable mode of transportation, we generally provide customers with the weight of the elbow.

What is the Steel Pipe Elbow?

Elbow is the most commonly used pipe fitting in pipe installation,Its function is mainly to change the direction of the piping system.They can be divided into some type that depend on the angle and connection methods.

Angle:90 degree elbow ,45 degree elbow.

Connection:butt weld elbow,threaded pipe elbow and socket weld elbow.

Radius:long radius elbow,short radius elbow,3d radius elbow.


What are the Methods to Calculate the Weight of the Elbow

No matter which way you choose, the butt weld elbow weight is calculated based on 90 Degree. Because 90 Degree Carbon Steel Elbow is the most common type.

1. Calculate according to the weight formula.

2. We have make the Elbow Weight Calculation Formula and Chart.

The chart below is about the weight of 90 degree elbow,if you need the weight of 45degree elbow,it equals to 0.6 times the weight of 90 degre elbow in the same size.Because 90 Degree Carbon Steel Elbow is the most common type.


Calculate 90 Degree Steel Elbow by Formula 

If we know the dimensions, such as outer diameter, wall thickness (mm), long radius (1.5D), or short radius (1D). We can calculate the weight of the elbow.


What is Formula of 90 Degree Elbow Weight ?

The weight formula is W=0.0387 * S*(D – S) * R / 1000, the unit is kg/piece. What’s the meaning of each letter? Let’s explain to you.

W means Weight.

S means Thickness in mm.

D means Outside Diameter in mm.

R means Radius that LR=1.5D, SR=1D.

Now we take “90 Degree Elbow LR Seamless 12″ Sch 40 BW ASTM A234 WPB” as sample. From above diameter and thickness chart, we know the outside diameter is 323.9mm and thickness is 9.52mm. The weight will be 0.0387 x 9.52 x (323.9 – 9.52 )x 1.5 x 323.9 / 1000 = 56kg/piece.
