Design Strategies for Polymer-Lined Flex-Hose Distance/Volume Pieces


Several strategies are presented for the design of “distance/volume pieces (DVPs)” used to cope with adiabatic compression hazards in the use of polymer-lined flexible hoses. A well-designed metal DVP located at the dead-end of a system will contain the hot gases produced during compression of the initial hose contents and spare the more easily ignited polymer from ignition. One design strategy contains the entire hot slug of gas within the DVP, the other contains all of the gas that nominally exceeds a given temperature. System modifications that might enhance the effectiveness of DVPs are also described.
