A distribution network needs to provide reliable flow while sustaining the integrity of its piping infrastructure exposed to the risks of water condensation, hydrants, corrosion, external coating failure, third-party damage, pressure fluctuations and ageing. In this respect, this review paper aims to propose a new integrated approach to advanced flow assurance and pipeline integrity management by combining hydraulic-thermal modelling, corrosion prediction, inspection results, risk-based maintenance, and digital decision support. Based on recent literature between 2020 and 2025, this paper identifies the connection between flow assurance concerns (hydrate formation, liquid holdup, scale, black powder and pressure stability) and integrity threats (corrosion, metal loss, denting, cracks, leaks and pressure drop). For this purpose, a systematic review methodology will be applied based on structured synthesis of relevant literature, thematic categorization and design of an integrated framework. As evidence, two tables with key literature references will be included as well as two diagrams representing the proposed integrated approach and decision-support dashboard. It is concluded that pipeline integrity management should not rely merely on inspection practices and hydraulic analysis, but it must include consistent data collection and integration, calibration of digital twins, probability risk estimates, explainable machine learning outcomes and proactive pipeline maintenance according to its flow integrity status. The main contribution of this study will consist in proposing a practical approach to advanced flow assurance and integrity management, which will satisfy the standards of international journals.
