Response Analysis of Buried Pipeline Subjected to Reverse Fault Displacement in Rock Stratum
Response analysis of the buried pipeline subjected to reverse fault displacement is very important for design, detection and protection of buried pipelines. This paper looks at the buckling behavior of a buried pipeline subjected to reverse fault displacement in the rock stratum. Effects of internal pressure, wall thickness, fault displacement and burial depth on the buckling mode and the axial...
متن کاملEvaluation of Seismic Protection Methods for Buried Fuel Pipelines Subjected to Fault Rupture
Buried steel fuel pipelines are critical lifelines for the society and the economy but are very vulnerable to earthquake-induced ground failure. Traversing seismic areas inevitably results in several pipe-fault crossings. Fault rupture forces a buried pipeline to undergo deformations that could be substantial and heavily endanger its integrity. Due to the grave consequences of a potential pipe ...
متن کاملRefinement to the Existing Analytical Methods of Analysis of Buried Pipelines due to Strike-Slip Faulting
Analytical methods presented to analyze the buried steel pipelines at strike-slip fault crossing use the Euler-Bernoulli beam theory. The cross-section of a buried pipe that is completely surrounded by soil cannot rotate freely and would not be remained perpendicular to the bending line after deformation. So it would be better to take into consideration a rotation between the cross-section and ...
متن کاملA SURVEY ON THE EFFECT OF SOIL COMPOSITION IN CORROSION BEHAVIOR OF CATHODICALLY PROTECTED BURIED PIPELINES UNDER AC INDUCED CONDITION
Abstract: Due to the expansion of high voltage Alternating Current (AC) power transmission lines and cathodically protected buried pipelines, it is becoming more and more difficult to construct them with enough safe distances between them. Thus, the pipelines are frequently exposed to induced AC interferences, which result in perturbation of Cathodic Protection (CP) due to AC corrosion. To s...
متن کاملTesting of Buried Pipelines Using Guided Waves
Introduction The inspection requirements of pipes that have an operational history of many tens of years have lead to the adoption of new maintenance practices and safety standards. The solution currently considered as best maintenance practice is the direct assessment of 100% of the pipelines with the minimum possible economical impact. The use of RBI (Risk Based Inspection) methods and the in...
