| Abstract: | The paper introduced the full scale simulated bend test equipment,method,procedure and test result of GSPU wet thermal insulation coatings of deep water submarine pipeline and joint SPU wet thermal insulation coatings.After comparative analysis on visual observation and mechanics performance testing before and after test,the results meet the requirements of ISO 12736—2011 Annex B and after bending test,the shear force between the joints and the coating of the pipe body and the steel pipe changes little.The good bending resistance of the coating of joint and pipe body is fully explained. |
