Marine engineering pipeline transportation of oil and gas resources of the main methods . Flexible pipe is a pipe in one, because they have better performance than steel and a large number used in marine engineering . The complex structure of the flexible pipe wall , in particular non- adhesion structure of the flexible pipe wall by a variety of non- bonded composite material , a special composite material , which is defined as a structured composite materials. Non-caking pipe friction between the middle and the layer , the contact as a result of nonlinear problems result of this structure analysis is difficult . Now that analytical and numerical analysis of methodological limitations need to verify the experimental methods and results of design verification. Therefore, this paper main task is to set up a method for the flexible pipe design verification test system . However , the flexible tube is a complicated structure , there is no standard test method can be based , the specimen length is longer , the existing standard test unit can not meet the flexible tube experiments. More importantly , for the verification experiment projects , design and method that requires analysis method based on a flexible tube , is still a lack of specific and device platforms . In this paper, design principles and design methods departure , through the elaboration of analytical methods , the lack of a clear analysis methods are given , including product testing, tensile test , torsion test , bending test , pressure test , external pressure pressure collapse experiments , the minimum bend radius experiment experimental lateral extrusion , axial compression and thermal expansion experiment experimental verification experiment design basis , for each experiment design and build , and then establish entire experimental system . In the set up of the system, two different structures on the flexible tube experiments, the design and analysis methods of verification , and gives to compare. This work contributed to the localization process of the flexible tube . Although the verification test system has been established, but need further improvement and further research . Future research work mainly includes two aspects , the first is the improvement of existing experimental systems , and the second is to design and build dynamic experiments , such as fatigue experiments .
