Experimental substantiation of the corrosion rate of pipe steel
Authors: Белостоцкий Михаил Андреевич , Короленок Анатолий Михайлович 
Published: September 2021

Определяющее значение в развитии дефектности металла труб имеет коррозионный фактор, а также деградация механических свойств трубных сталей в процессе эксплуатации трубопроводов. Авторами приведены результаты экспериментальных исследований по оценке скорости коррозии и склонности к трещинообразованию трубных сталей, наиболее распространенных на длительно эксплуатируемых магистральных нефте- и нефтепродуктопроводах. Разработана методика определения количественных показателей коррозионно значимых параметров для обоснования вывода в капитальный ремонт трубопроводов на основе результатов натурных экспериментальных исследований скорости коррозии фрагментов трубной стали при различных условиях поляризации и коррозионной активности грунта. Объект исследования - фрагменты труб (пластины) 50×50×3 мм, изготовленные из стали марок 09Г2С и 17Г1С. Полученные результаты позволили сформулировать рекомендации по уточнению количественных критериев коррозионно значимых факторов для обоснования вывода трубопровода в капитальный ремонт: 1) необходимо учитывать марку трубной стали (установлено, что сталь 17Г1С на 20-30 % более устойчива к коррозии, чем сталь 09Г2С, особенно в части образования локальных повреждений - язв и питтингов); 2) при значениях удельного электрического сопротивления грунта менее 20 Ом⋅м скорость коррозии возрастает примерно на порядок независимо от марки стали и наличия системы электрохимической защиты.
This work presents the results of experimental studies on the assessment of the corrosion rate and the cracking tendencies of pipe steels, most common in the main oil and oil product pipelines that have been used for a significant amount of time. A methodology was developed for determining quantitative indicators of corrosion-significant parameters to justify the overhaul of main pipelines based on the results of field experimental studies of the corrosion rate of pipe steel fragments under various conditions of polarization and corrosive activity of the soil. The object of the study is pipe fragments (plates) with the dimensions of 50×50×3 mm, made of steel with the grades 09G2S and 17G1S. The results made it possible to formulate recommendations for refining the quantitative criteria of corrosion-significant factors to justify the overhaul of the pipeline: 1) it is necessary to take into account the pipe steel grade (it was found that 17G1S steel is 20-30 % more resistant to corrosion than 09G2S steel, especially in the formation of local damages - corrosion pits and pittings); 2) at values of specific soil resistance less than 20 Ohm⋅m, corrosion rate increases by about an order, regardless of the steel grade and the usage of an electrochemical protection system.

Цель настоящего исследования - оценка влияния локальной термической обработки (нормализации и закалки с отпуском для продольных сварных соединений труб, сваренных контактной сваркой токами высокой частоты, а также высокотемпературного отпуска и термического отдыха для кольцевых стыков трубопроводов, сваренных дуговой сваркой) на показатели механических свойств и металлургического качества металла сварных соединений. Для проведения исследований в области продольных сварных соединений использовались трубы диаметром 530 мм с толщиной стенки 10 мм класса прочности К56, для оценки свойств металла кольцевых стыков были выбраны катушки длиной 500 мм с односторонней симметричной разделкой кромок с углом скоса 30°, изготовленные из труб диаметром 219-530 мм с толщиной стенки 8-15 мм из сталей класса прочности К42, К48, К56. В частности, показано, что высокий отпуск повышает пластичность, снижает уровень остаточных сварных напряжений (более чем на 30 %), твердость и прочность. Термический отдых сварных стыков способствует снижению уровня остаточного водорода в металле сварных соединений, что позволяет повысить свариваемость трубной стали при проведении ремонтных работ. В целом сделан вывод о том, что локальная термообработка позволяет оптимизировать показатели механических свойств металла сварных соединений и при необходимости получать требуемый уровень механических свойств.
The purpose of this study is to assess the effect of local heat treatment (normalizing and quenching with tempering for longitudinal welded joints of pipes welded through contact welding with high frequency currents, and high-temperature tempering and cooling for arc welded circular joints of pipelines) on the mechanical properties and metallurgical quality of welded joint metal. To carry out research in the field of longitudinal welded joints, pipes with a diameter of 530 mm and a wall thickness of 10 mm with the K56 strength grade were used; to assess the metal properties of ring joints, 500 mm long spools with unilateral symmetrical beveling with a bevel angle of 30°, made of pipes with a diameter of 219-530 mm with wall thickness of 8-15 mm made from K42, K48, K56 strength grade steel, were used. In particular, it is shown that high tempering increases ductility, reduces the level of residual weld stresses (by more than 30 %), hardness and strength. Cooling of welded joints helps to reduce the level of residual hydrogen in the welded joint metal, which increases the weldability of pipe steel during repair works. In general, it is concluded that local heat treatment allows to optimize the indicators of mechanical properties of the welded joint metal and, if necessary, to obtain the required level of mechanical properties.

Установки водяного охлаждения резервуаров являются частью системы автоматического пожаротушения резервуарного парка и представляют собой комплекс устройств, оборудования и трубопроводов. Непосредственное охлаждение стенки резервуара осуществляется через верхнее горизонтальное кольцо орошения, выполненное в виде перфорированного трубопровода или трубопровода с оросителями. При этом до настоящего времени не была определена зависимость фактически защищаемой площади стенки от расходов воды, подаваемой через отверстия и/или оросители при их различном положении по отношению к стенке и верхней кромке резервуара. Цель исследования - экспериментальное определение оптимальных конструктивных и технологических решений элементов установок водяного охлаждения резервуара. Для изучения процессов теплового нагрева и охлаждения боковой поверхности резервуара проведены гидравлические и огневые испытания моделей секции установки водяного охлаждения - горизонтального кольца орошения. По результатам испытаний определена эффективность различных конструкций в зависимости от изменяемых технологических параметров (давления и расхода воды в кольце орошения), диаметра отверстий перфорированного трубопровода и шага между ними, угла расположения устройств подачи воды относительно горизонтальной поверхности сечения резервуара, расстояния от кольца орошения до стенки резервуара и его верхней кромки.
Water cooling units for tanks are a part of automatic fire extinguishing system of the tank farm and represent a complex of units, equipment and pipelines. Tank wall is cooled down directly through upper horizontal spray distribution ring, made in the form of a perforated pipeline or a pipeline with sprinklers. With this, correlation between actually protected area of the wall and flow rate of water supplied through the holes and/or sprinklers at their different positions in relation to the wall and the upper edge of the tank, has not been determined so far. The purpose of the study is to experimentally determine the optimal design and technological solutions of the elements of tank water cooling units. To study the processes of thermal heating and cooling of the side surface of the tank, hydraulic and fire tests of models of the section of the water cooling unit (the horizontal spray distribution ring) were carried out. According to the test results, the efficiency of various structures was determined depending on the technological parameters being changed (pressure and water flow in the spray distribution ring), diameter of the holes of the perforated pipeline and pitch between them, angle of the water supply units relative to the horizontal surface of the tank section, distance from the spray distribution ring to the tank wall and its upper edge.

Ética histórica
Authors: Pegoraro Olinto A. 
Published: September 2021

A Ética, enquanto discurso filosófico, estuda os comportamentos humanos na perspectiva de sua origem, articulação e avaliação. Por comportamento entendemos os hábitos aceitos pela média de uma comunidade num determinado momento e espaço cultural.
Esta conceituação desde já coloca em destaque dois elementos capitais da composição do comportamento humano: o processo cultural e o processo temporal. Nossos comportamentos são um tecido vivo como a língua que falamos; formam-se, crescem e podem desaparecer cedendo lugar a outros modos de ser da existência, ou seja, a outros estilos de vida.
