Abstract:
When conveying a hot medium, constrained pipe-in-pipe (PIP) systems are highly compressed spring systems prone to the release of strain energy by inner pipe buckling. This paper proposes a series of closed-form formulations for the potential inner pipe displacement response and its associated stress/strain condition. Verified by finite element analysis and past company projects, the derived formulae are a useful evaluation tool for PIP component design and assessing through-life integrity risks to the PIP insulation material.
