| Abstract: | The mechanical and creep properties of polyurethane elastomer as thermal insulation layer of subsea wet-type thermal insulation oil pipeline are very important parameters. This paper analyzes the forces on polyurethane elastomer thermal insulation layer of subsea pipeline on seafloor,calculates the compressive deformation of the layer,and designs the creep test device for polyurethane elastomer,then gives the creep test procedure and the test results based on a practical instance. |
