Methods of optimal planning of material resources in the production of pipes

The article characterizes the current trends and real state of steel pipe market in the Russian Federation. The structure of prime cost assessment of pipe metal products is considered, its basis role in metal expenditures is educed. The importance of optimal planning of material resources for the improvement of production economic effectiveness is mentioned. The characteristics and comparison of the main known methods such as reporting and statistics, experimental and computational-analytical methods of regulation of metal expenditure in the pipe production are considered. Their advantages and disadvantages are also mentioned. The authors consider the genesis of computational-analytical method which is the most progressive because of the possibility of establishing the target standards of materials consumption and regulations, reflecting the real maintenance level of technological processes. The calculation of materials consumption coefficient and expenditure rate of the metal in the technological cycle and redistribution by computational-analytical method is analyzed in details. The authors prove the applicability of the regulation of the metal consumption according to technological redistribution that meets current requirements to the consideration and prime cost assessment of the production. At the same time, the increased labor coefficient of the full-scale implementation of computational-analytical method which lies in the need for ongoing analysis and systematization of significant package of input data describing the entire assortment of manufactured pipes, as well as in the need of committing the changes in technological processes that affect their numerical values. The scientific and technical work on the development and application of computational-analytical method of regulation of metal consumption in the production of steel seamless and welded pipes in the enterprises of "Pipe Metallurgical Company" OJSC is presented. The main results are given and the economic feasibility of the introduction of computational-analytical method of the metal consumption regulation is formulated.
