QUALITY STUDIES OF PLASTIC PARTS OILFIELD EQUIPMENT

Abstract

The article considers the quality of plastic parts of oilfield equipment depending on the modes of manufacturing their various designs and the composition of press materials. By adjusting the regime parameters in the manufacture of parts, quality indicators are determined: tensile strength, hardness of parts, and others. The use of parts made of plastic materials for the development of the oil field equipment industry can be considered efficient from a technical and economic point of view. Also, in order to improve the quality, strength and longevity, plastic masses, which are an alternative product to metals and non-metals, have started to be used. Studying the performance indicators of the used plastic materials is considered mandatory. The quality of details made of plastic masses depends on many factors, and the indicators of these factors appear during operation. The quality indicators of products made of plastic materials in oil field equipment are distinguished by the presence of unlimited possibilities, greater than structural materials. Parts made of such materials have high performance indicators and are used in the preparation of parts with different constructions using uncomplicated processing methods. For the development of the oil industry, ways to increase the durability and longevity of the equipment used in this industry should be investigated. Based on the results, an experimental-theoretical method for determining the main quality criteria (shrinkage deformation and other quality indicators, strength, hardness, surface roughness) of plastic parts is proposed. The developed technique for the design of plastic parts makes it possible to estimate the expected life of parts, taking into account their operating conditions. Keywords: quality, plastic parts, press materials, performance, shrinkage.
