The Practical Test on the Full Scale 529mm Pipeline with Combined Actions of Bending and External Pressure

By the practical testing result on 529mm pipeline with combined actions of bending and external pressure, it has shown that pipeline stress state has a good film stress state.This result totally supports the regulations of Offshore Pipeline Code by Det Norske Veritas for pipeline pressure design, In addition, the test also shows that the result has no difference between iterative addition of various single loadings and compound loadings.
