AS 2885.1 Pipeline Combined Stress

Calculate AS 2885.1 pipeline longitudinal stress and combined stress.

The stress check can be performed for longitudinal stress, Tresca stress and von Mises equivalent stress. Pipe axial load can be calculated for fully restrained pipe, unrestrained pipe, user defined external or global load, and user defined wall load. Bending moment can be calculated for in plane bending, out of plane bending, or combined in plane and out of plane bending. The stress concentration factors ii, io and it can be used for in plane, out of plane and torsion shear stress in pipe fittings. For straight pipe ii, io and it equal one.

CALCULATOR : AS 2885.1 Pipeline Diameter And Wall Thickness Schedule [FREE] ±

Calculate AS 2885.1 pipeline diameter and wall thickness.

The pressure design wall thickness is equal to the nominal wall thickness minus the corrosion allowance. The fabrication allowance is accounted for in the design factor (an additional fabrication allowance is required in some cases). Select the pipe schedule (NPS or ISO etc), pipe diameter and wall thickness, or use the user defined option. Use the Result Table option to display the pipe schedule with nominal wall thickness and pressure design wall thickness for the selected diameter.
