“…4 are found to be within the bounds of the expected P min and P max values from equations (7) and (8). Hence Faupel's bursting pressure formula (6) gives failure pressures close to the test results (see Table 3). The discrepancy in the predictions from Faupel's bursting pressure formula (if any) may be due to variations in the strength properties of the vessel material.…”

“…Commonly, analyses using FEM study the capacity of corroded pipelines to resist to internal pressure, investigating, for example, the influence of material properties [14] and parameters of the defects [15]. FE models are generally validated with experiments and compared to results obtained by analytical methods.…”

In this work, failure prediction of corroded pipelines under combined loads of internal pressure and axial compressive force is investigated through the Finite Element Method. The study was carried out using the PIPEFLAW program, which was specially developed to automatically generate and analyze corroded pipelines models. Two configurations of idealized defects in pipeline were investigated: with two and three rectangular defects. This work was divided into two stages where, on the first stage, the analysis is performed considering only internal pressure. On the second stage, combined loads are simulated considering internal pressure and axial compressive forces. Results show that failure pressure values decrease with the increase in the axial compressive force, for both Finite Elements models analyzed.

“…The other is the PWT location, which is important for the detection and maintenance of in-service pipes, especially long-distance pipes. Recently, many researchers have focused on developing nondestructive testing (NDT) techniques for detecting PWT defects, including infrared thermography, 3) X-ray, 6) electrical potential drop, 7) ultrasonic, 8,9) magnetic flux leakage, 10) eddy current method, 11) elasticplastic finite element analysis 12) and so on. However, they can only inspect a pipe locally except for the hollow cylindrical guided wave (HCGW) of ultrasonic method.…”

This research aims to find an efficient and nondestructive way of detecting the locations of the pipe wall thinning (PWT) in a long-distance metal pipe at open-end condition. Time domain measurement of microwave signals is adopted in the method since microwaves can propagate a long distance with low attenuation in the pipe and reflection occurs at the PWT section. To carry out the measurement, a vector network analyzer and a self-designed coaxial-line sensor were used to generate microwave signals propagating in the pipe. By analyzing the time domain response of the signals and extracting the time of flight (TOF) that corresponds to the PWT location, the locations are quantitatively evaluated after the group velocity of the signals propagating in the pipe was calibrated. In order to approach a pipe with different PWT degrees and locations, three brass pipes with an inner diameter of 17.0 mm and lengths of 453 mm, 455 mm, and 2000 mm, respectively, were used in the experiment. In addition, five joints, which have the length of 17.0 mm and inner diameters from 17.10 to 18.20 mm were also used. The arithmetical mean error of the evaluation for PWT locations is found to be less than 1.7 mm, i.e. less than 0.068% of the length of the corresponding pipe. It indicates that a quite efficient and precise method to remotely and quantitatively evaluate PWT locations in a long-distance pipe has been established.
