... of the five interaction rules such as DNV RP F101, API 579, BS 7910, Kiefner and Vieth, Pipeline operator forum (POF) on failure pressure are evaluated. INTRODUCTION Due to the harsh environment and the role of aggressive medium, failures of oil/gas transmission pipelines with corrosion defects become...

... spacings between defects, the cases related to 13 types of colony of defects are computed. Based on the ratio of failure pressure of each case to the failure pressure of corresponding base case, the interaction between defects is determined. Then for X80 steel, a new interaction rule is proposed...

... ABSTRACT In this work, several industrial codes that are available for assessment of pipeline failure pressure were evaluated with respect to the grade of pipeline steels and the geometry of corrosion defect. A novel, finite element-based CX model was developed to simulate the complex stress...

... by the small scale model test are simplified with respect to their duration and skewness. Dynamic analyses of Mark-III LNG CCS are then parametrically performed with the consideration of various types of sloshing impact. Meanwhile, the failure pressures given the duration and skewness are investigated after...

.... The failure pressures measured in the burst tests are compared with those predicted by six assessments methods, namely: the ASME B31G method, the RSTRENG 085dL method, the DNV RP-F101 method for single defects, the RPA method, the RSTRENG Effective Area method and the DNV RP-F101 method for complex shaped...

... capacity is discussed as well. From the FE results, a set of limit solutions are proposed to predict failure pressure of submarine pipeline made of X60 steel with long longitudinal corrosion defects. The burst capacities predicted by the proposed solutions are compared with the results from laboratory...

... A new method for the prediction of the failure pressure of pipelines containing colonies of corrosion defects was proposed in a previous paper. This method, named MTI method, can take into account the length of full wall-thickness pipe that exists between each pair of defects within a colony...

... ABSTRACT A modified version of the RSTRENG 085dL method was proposed in a previous paper. This method, named RPA method or Modified 085dL method, uses two different equations to predict the failure pressure of a corrosion defect. The equation for short defects is the same equation used...

... ABSTRACT This paper investigates the relation between the two classic strength failure criteria, i.e. the Tresca and von Mises criteria, and their role in predicting failure pressure of line pipes with or without corrosion defects. The objective of this paper is to determine practical...
