Corrosion Protection of Metal Structures in Manufacturing Conditions

Abstract

The purpose of the research is to improve the quality of secondary protection measures during the production of sheet metal structures. The article is also aimed at maintaining the quality with guaranteed indicators of durability, taking into account the level of corrosion hazard in a coastal climate. Methodology Process approach principles were used to implementing the tasks of lifetime control in corrosive environments. The reliability principle of corrosion hazard level is ensured, which is described by the successive stages of assessing the survivability of sheet metal structures based on the DMAIC (define, measure, analyze, improve, control) strategy: terms, measurement, analysis, improvement and control of primary and secondary corrosion protection measures. Results Corrosion protection measures have been developed according to the criterion of corrosion hazard, which ensures compliance with the reliability requirements of building metal structures based on the calculated indicators. Solution of management tasks has been found. Those were concentrated on the technological readiness within determined period which is prior to the construction of the building object. Scientific Novelty We have been able to design maintenance procedure for sheet metal under the actual conditions, which is based on a process approach to resource management by building a system of accounting and functional control, risk analysis and management of process safety. Implementation of these principles at the object level is supposed to improve the means and the methods of corrosion protection, resource extension, taking into account indicators of vitality and justification of reliability measures program (RMP). Practical Relevance Based on the developed principle, the results of field and laboratory studies have been generalized. These studies are focused at substantiating the primary and secondary protection of sheet metal structures under the given level of corrosion hazard, which is proposed by RMP organizational measures. The arrangements contain evaluation of integral constructive characteristics of adaptability, technological rationality and risk analysis of corrosion hazard signs.
