Bainitic steel containing approx. 2.25% Cr and 0.6 Mo with micro-additions of V, Ti, B, designated as 7CrMoVTiB10-10 (T/P24), is one the new construction materials used in supercritical power units. The weldability defined hot-cracking susceptibility, it should be stated that hot cracking welded joints 7CrMoVTi10-10 determined by phenomena occurring high-temperature brittleness range (HTBR). In...
In the research presented in this paper, a failure analysis were carried out to identify causes of an incident, which had taken place after an operation to repair a leak in an interstate natural gas pipeline. In this operation, a partial encirclement reinforcement (patch) was welded to the carrier pipe according to an available hot taping procedure, while gas was flowing in the pipeline. The fa...

Variant Stochastic cracking is a significantly more resilient approach to adaptive indexing. It showed [1]that Stochastic cracking uses each query as a hint on how to reorganize data, but not blindly so; it gains resilience and avoids performance bottlenecks by deliberately applying certain arbitrary choices in its decision making. Therefore bring, adaptive indexing forward to a mature formulat...
