Experimental Design of Quasi-static Buckling Propagation in Deepwater Sandwich Pipelines
In addressing one of the predominant failure mechanisms of submarine pipelines,we propose a design of sandwich pipe for a quasi-static buckling propagation experiment.This design utilizes SS304 stainless steel for both inner and outer layers,with high-density polyethylene as the intermediate layer.A scaled model of the sandwich pipe is meticulously designed and fabricated.The quasi-static buckling propagation experiment is then executed within a deep-water high-pressure chamber.Our findings affirm that the experiment design successfully meets the requirements for quasi-static buckling propagation pressure testing of the sandwich pipe.The derived buckling propagation pressure data serve as a valuable reference for foundational structural design and practical engineering applications of the sandwich pipe.
