Allowable Stress Values for Lifting Pressure Vessel through Lifting Lug

Allowable Stress Values for Lifting Pressure Vessel through Lifting Lug

Allowable Stress Values for Lifting Pressure Vessel through Lifting Lug

Dear Tom Barsh
As Mentioned in the Help topic In Compress
"As well there is an option to reset all the allowable stress values based on the vessel material yield stress of the component to which the lift lug is attached. This is useful if the lug material is the same as the vessel component material. Default stress values are tensile = 0.6*Sy, bearing = 0.9*Sy, bending = 0.67*Sy, shear = 0.4*Sy."

Can you please tell us the Reference from where these "Default values" or "Default Factors" of Stresses has been taken in calculation of Compress any code Standard or any Engineering Practice ?
