Tube Pipe Circumference Butt Weld With Torque Joint Calculation

Weld Design Menu

The following equations will determine the circumeferential stress applied to a a welded joint under going torque loadings.

Tube Pipe Circumference Butt Weld With Torque Joint

Circumference Butt Weld Stress with Torque Shear Stress

Circumference Butt Weld Stress with Torque Shear Stress Formula

Where:

= Shear stress [MPa,psi]

u

= Constant
                Metric units u=1000
                Imperial units u=12
W = Section modulus throat area [mm3, in3]

T

= Torque applied [Nm, lb-ft]

Comparative Stress 

Comparative Stress Formula
Where:

= Comparative stress [MPa,psi]
= Shear stress  [MPa,psi]
= Conversion coefficient of weld joint
