    Assessment of integrity of operating gas pipelines
    (Wydawnictwa AGH, 2018) Ładecki, Bogusław; Matachowski, Filip; Bednarz, Stanisław
    Gas pipelines that have been in operation for many years require supervision, taking into account the places and conditions of their usage. The currently applicable normative regulations do not fully determine the scope of the integrity control of such gas pipelines. The standards provide general guidelines for monitoring corrosion phenomena in pipelines, allowing the use of simplified strength patterns based on a flat state of stress, in actuality, real objects usually have complex three-dimensional structures. Such an approach may be a reason for committing significant errors in determining the state of stresses and strains in the construction of pipelines, which is a significant problem in assessing the integrity of pipelines (when combined with the lack of a formulation of the appropriate admission criteria). This paper presents a methodology for assessing the integrity of pipeline structures operating at ambient temperatures based on conducting comprehensive measurements of wall thickness defects (in connection with performing necessary defectoscopy tests). The results of these measurements and non-destructive tests are the basis for the analysis of stress strength and MES deformation based on the verified real geometry as well as the method of supporting the pipelines. The information obtained on this basis regarding the pipeline structure areas of the highest efforts is the basis for selecting the critical areas of pipeline construction for which they should be repaired or modernized, or a monitoring program should be developed using non-destructive tests.

    Potrzeba opracowania własnych urządzeń diagnostycznych do automatycznej oceny stanu taśm przenośnikowych w kopalniach odkrywkowych
    (Wydawnictwa AGH, 2011) Błażej, Ryszard; Jurdziak, Leszek; Zimroz, Radosław
    Review of available on the market conveyor belt inspection tools for assessment of their condition has shown lack of openness of ready solutions on cooperation with existing in mines belt databases and lack of possibility to create own applications based on source diagnostic signals with usage of additional information from these databases. This situation induce authors to create the machine vision device for belt cover inspection and process source signal from magnetic scanner of belt cord. The aim is to work out comprehensive set of devices and algorithm processing collected data and making integrating evaluations of belts condition in order to aid taking rational decisions about their replacements taking into consideration possibility of effective and economically profitable belt refurbishment. System will be not only used for assessment of belt and its core condition, but also will protect belt and conveyor before catastrophic event such us longitudinal rips. It will also create schedules of essential repair works. Due to close cooperation with future users the worked out system should very well fulfill their needs. They can be taken into account at the design stage and during defining its functionality. Authors of solutions have decided to put more attention on possibility of automation of carried out assessments and their recording in databases in order to minimize necessity of human interpretation and intervention everywhere it will be possible. Quality financial analysis has shown that it is possible to lower total transportation cost increasing expenditure on automatic diagnostics of conveyor belts.
