Stress analysis of pipelines with small misalignment under internal pressure using fast modelling system ABAP

This paper presents a numerical finite element analysis of pipelines with small misalignment under internal pressure using developed fast pipeline modelling system ABAP Python development environment ABAQUS. The effect is shown to affect at most 10% stress levels. Extensive parametric analyses have been conducted on the pipe length, thickness. Pipe length has trival non-uniform distribution when length/diameter ratio greater than 1. For thinner pipe, amplifies circumferential non-uniformity more significantly thicker pipe. serves enhance understanding pipes installation defects pure pressure.
