Numerical Analysis of Hybrid Composite Piping for Oil and Gas Application

The advantage of composite material over conventional engineering materials
stem largely from their high specific strength, stiffness and fatigue characteristics.
Composite materials over the years have emerged as a strong contender for replacing
steel in piping application. The research is focuses on the design and mechanism of
drill pipe used in the drill string. The design of the drill pipe will take into account
the analysis on the two main factors of process and material parameters with regards
to stress distribution and strength-to-weight ratio. Furthermore, the study only
concentrates on the composite pipe fabricated based on only the filament winding
technique used for manufacturing open (cylinders) or closed end structures (pressure
vessels or tanks). The design properties of the drill pipe will be determined with
regard to different material composition. The analyses on these two parameters will
indicate whether the composite drill pipe could possibly be used to replace the
conventional steel pipe. For that purposes, the research will be carried out using the
models developed via the mathematical calculation and finite element analysis
(FEA) on ANSYS codes.
