Triaxial-Load-Capacity Diagrams Provide a New Approach to Casing and Tubing Design Analysis

Abstract

Summary A computer program has been developed that generates a two-dimensional (2D) graphic representation to display the effect of anticipated service conditions on specific casing and tubing. The triaxial-load-capacity diagram permits a visual determination of string design adequacy by both API and equivalent-triaxial-stress design factors. The program is useful in the design and analysis of any casing or tubing string.
