AS 2885.1 Pipeline Allowable Stress

Calculate AS 2885.1 pipeline yield stress and allowable stress.

Select the appropriate stress table (API, ASM, DNV etc), material, and design factor. Use the Result Table option to display the results for the selected stress table (click the Result Table button on the plot bar, then click the make table button). The pressure design thickness equals the nominal wall thickness minus the corrosion allowance. The fabrication allowance is only required for pipes where the fabrication tolerance exceeds the relevant specification (for example some grades of seamless pipe).

CALCULATOR : AS 2885.1 Section 5.4.3 Pipeline Allowable Stress [FREE]   ±

Calculate pipeline allowable stress from specified minimum yield stress (SMYS) and design factor (AS 2885.1 section 5.4.3).

Use the Result Table option to display a table of SMYS and allowable stress versus material grade for the selected material schedule.
