The oil and gas industry of the Republic of Kazakhstan, as one of the leading branches of industrial production, is the basis of economic development and largely determines the economic independence of the country. In the oil and gas industry, a column of tubing is used to transport oil or gas and operates under extreme operating conditions. Threaded connections play a crucial role in ensuring the service purpose of pipes. Threaded connections in the process of lifting and lowering operations and work in the well are exposed to various forces: stretching, compressing, bending, etc. In order to increase the service life of the tubing, the thread has to be re-threaded in the process. In order to improve the quality of the threaded connection, it is urgent and necessary to solve the problem. In this article, a new combined two-stage metal cutting tool: a comb cutter and a method for cutting internal threads have been developed. By using this, two or three hole preparation operations can be integrated into one operation. The prediction of the operational properties of the threaded pipe-coupling connection, the distribution of the causes of destruction of oil grade pipes is given.
