Solution of the Problem of Operational Reliability and Environmental Safety of Transport Pipeline Systems

摘要

Ensuring technogenic and environmental safety of transport pipeline systems is a complex state task. The main group of reasons leading to failures, accidents and other incidents in these systems is associated with the quality of manufacture (repair) of equipment, as well as the level of operation of transport pipeline systems. At the present stage of transport pipeline systems development, the design-technological approach, including the maintenance and repair of valves, is significantly changing. Particular attention is paid to the abrasive finishing and lapping treatment, which allows, in one operation, carrying out first the roughing (allowance removal), and then the final finishing with achievement of the shape and dimensional accuracy of the workpiece. The proposed calculated dependences allow predicting the operation reliability and durability of high-precision products of transport pipeline systems valves and, thus, increase the level of environmental safety of transport pipeline systems.
