PHYSICAL-CHEMICAL, MECHANICAL AND OPERATIONAL TESTS OF OIL AND GAS PIPES OF INCREASED CORROSION RESISTANCE

Abstract

Introduction. One of the main reasons for the failure of pipes and other equipment operated in the oil and gas industry is metal corrosion caused by the presence of heterogeneous liquid and corrosively active components in formation waters and well products that surround them: chlorides, carbon dioxide, hydrogen sulfide [1−3]. Corrosion significantly shortens the useful life of equipment, leads to accidents in oil and gas industries, causes significant economic losses and pollutes the environment [1−5]. The most susceptible to corrosion are pump-compressor pipes (РСР), because they are in the most difficult conditions during operation. At the same time, the vast majority of destruction occurs along the thread [1, 5]. Therefore, the reliability and durability of equipment at oil and gas fields is determined by the rational choice of structural materials and pipe manufacturing technologies.
