Ensuring the strength and sealing of flange connections used in oil mining equipments

Abstract

The article discusses the tightness of flange connections used in oil field equipment, provides information about leakage of metallic gaskets. The research results is directed the development og metallic gaskets. Experimental explorations on the sealing of gaskets have been conducted. Based on the obtained analytical expression a graph of functional dependencies was constructed. Tests of metallic gaskets have performed on automatic equipment. Key words: flange connections, sealing, metallic gasket, elastic modulus, leakage rate, compressive stress, medium pressure
