TECHNOLOGICAL ASPECTS OF ASSESSMENT OF RELIABILITY, QUALITY AND ENVIRONMENTAL SAFETY OF SUPPLEMENTARY MATERIAL FOR MANUFACTURE OF TRANSPORT PIPELINES

Abstract

When carrying out finishing (finishing and lapping) operations necessary for the manufacture (repair) of products of transport pipeline systems, special attention is paid to the auxiliary materials necessary for the imple-mentation of this technological process. The basis of these materials are chemically active, surfactant, flammable and explosive substances of organic and inorganic origin, developed according to a certain recipe in a strict combination of ingredients and with high requirements for quality output. During the implementation of the technological process of manufacturing or repair of products of transport pipeline systems, the auxiliary material is often considered as a kind of random process that has a certain impact on the environmental safety of these systems. This material for technological purposes is characterized by a num-ber of indicators that do not have numerical values, but to interpret them it is necessary to build a system of logi-cal and analytically related relationships, taking into account the required formulation of auxiliary material. In practice, these indicators of the material represent some criterion (criteria), which in the n-dimensional space can be represented as a vector of the technological state of the auxiliary material on the basis of its integrated evalua-tion. At present, a general scheme of work on the automated design of the formulation of auxiliary material based on the aggregate design method has been developed. The task of this method is to give the developed auxiliary material the maximum potential energy, as well as to increase its shelf life and reduce the risk of environmental impact. In addition, there are certain requirements for the ingredients of the material, and the formulation of the auxiliary material is based on the use of such ingredients that would ensure the reliability, quality and environ-mental safety of the operation of transport pipelines.
