“…Nonetheless, several questions are still unanswered in the context of hydrogen-induced cracking enlargement in relation to (i) increased crack formation rate relative to hydrogen diffusion rate at the tips, and (ii) the contribution of hydrogen to improving plasticity as well as the likelihood of fracture. Nazarova et al 59 demonstrated that temperature increases in proximity to a pipe result in decreased SCC susceptibility. For pipes operating in an H 2 S environment, optimum temperatures were defined as being between 20°C and 50°C due to a protective mackinawite (FeS) film.…”

The effective operation of water management systems is contingent upon leak localization and detection – a common problem that is more acute in large networks. This paper reviews the salient literature in this context and demonstrates the effectiveness of leakage location methods (LLMs) and leakage detection methods (LDMs). Although there is a significant amount of literature that discusses leakage localization and detection technologies, an academic lacuna still exists concerning the linkage between degradation mechanisms and LDMs and do not cover or connect past efforts from the start of a degradation mechanism that leads to changes in the mechanical strength (such as a reduction in fracture toughness) of pipes and results in crack propagation and leakage. This review focuses on these issues in the context of degradation mechanisms and common detection methods.

“…Cooling to reduce environmental temperature may result in un-envisaged operational problems in service application of the material that are not related to corrosion per se. The method can be feasible only in confined environments such as engines and boilers but not open atmospheric space, and vast water and soil environments [15].…”

The paper highlights 300M steel as an engineering material that is commonly used in special applications where fracture toughness, ductility, and ultra-high strength in the 2000-2070MPa range is required such as aircraft landing gear, airframe parts, undercarriage components, gears, shafts, and bolts. Stress corrosion cracking (SCC) is recapitulated as the drawback of the steel in its service applications. The aim of the paper is to call attention to the SCC problem and highlight the pros and cons of the existing alleviation methods for better appreciation of the way forward. The overview indicates interminable positive research inputs in alleviating SCC of the steel in its service applications by; use of coatings, heat and surface-treatments, inducement of surface compressive stresses, design techniques, and cathodic protection. It is however seen that SCC alleviation of the steel has not yet reached ideal level due to some impracticability and cost implications in using the SCC control methods in many cases, and no better alternative material has been found for the steel. Only few research inputs on the numerous environmental types that the steel can be in service contact with are found in the literatures for its SCC alleviation. Improving practicability and versatility of the existing SCC alleviation methods and optimization of SCC-susceptibility test information of the steel from much larger number of the environmental types and their various levels of combinations are deemed needful towards ideal SCC alleviation of the steel
