These days there are undeniably unique materials that, however, must also meet demanding safety requirements. In the case of vehicles, these are undoubtedly excellent fire protection characteristics. The aim of the work is to experimentally verify the proposed material compositions for long-term heat loads and the effect of thickness, the number of laminating layers (prepregs) as well as structures with different types of cores (primarily honeycomb made of Nomex paper type T722 of different densities, aluminum honeycomb and PET foam) and composite coating based on a glass-reinforced phenolic matrix. The selected materials are suitable candidates for intelligent sandwich structures, usable especially for interior cladding applications in the industry for the production of means of public transport (e.g., train units, trams, buses, hybrid vehicles).

Представлены результаты анализа экспериментальной и аналитической оценки огнезащитной эффективности покрытий для стальных конструкций. Обобщены данные многолетних исследований по определению зависимостей от температуры таких теплофизических характеристик, как теплопроводность и теплоемкость. Разработана структурно-методологическая схема выбора огнезащитных покрытий для стальных конструкций в целях обеспечения нормативных требований по огнестойкости. Проведены экспериментальные исследования по определению огнезащитной эффективности терморасширяющихся покрытий на эпоксидной основе при воздействии температурного режима горения углеводородов. Рассмотрен вопрос о гармонизации методики экспериментальной оценки огнезащитной эффективности средств огнезащиты для стальных конструкций с действующими европейскими нормами. Установлены критерии выбора пассивной огнезащиты, зависящие от области применения способов огнезащиты. Steel structures have high strength, relative lightness and durability, but when exposed to high temperatures in a fire, they deform, lose stability and load-bearing capacity. The collapse of load-bearing steel structures can occur in 10-15 minutes after the fire start. The actual fire resistance limit of structures can be increased by using the active and passive fire protection systems. The use of the active system for increasing the actual fire resistance limit is not provided in the regulatory documents. Passive fire protection is a complex of technical solutions including the use of non-flammable materials and bulging compounds. It is also an integral part of the building structure that ensures the required fire resistance limit. Assessment of fire resistance of building structures of residential, public, warehouse and industrial buildings is carried out taking into account the temperature regime (cellulose) of a standard fire. At oil and gas, petrochemical enterprises as well as at oil production platforms fires can occur at combustion of various hydrocarbon fuels which are characterized by a rapid temperature increase to 1100 °C. In this case, in accordance with GOST R EN 1363-2-2014, the temperature regime of hydrocarbon combustion is used to assess the fire resistance of building structures. The fire-retardant effectiveness of fire protection means for steel structures is determined by the heating time of the standard I-shaped column without applying a static load on the sample to the average “critical” temperature of the steel of 500 °C. Materials used for fire protection of steel structures must have a good thermal insulation ability, which is estimated by the coefficient of thermal conductivity. When heated to high temperatures, the thermal conductivity coefficient of fire-resistant materials varies depending on their composition and temperature. Based on the analysis of research to determine the fire-retardant effectiveness of fire protection means for steel structures there was developed a structural and methodological scheme that allows to make a choice of fire protection. Currently, as a fire protection there are widely used intumescent paints and thermo-expandable coatings. Taking into account the lack of knowledge of the influence of long-term operation and a large number of other technological factors on the fire-retardant effectiveness of coatings of steel structures covered with intumescent paints, it would be right to limit the use of such type of fire protection for load-bearing structures contributing to the overall sustainability of buildings with a required fire resistance of R 30. For fire protection of steel structures of oil and gas facilities located in the open air, in severe climatic conditions and exposed to aggressive environments there is successfully used a thermo-expandable two-component epoxy-based coating. The analysis of experimental data showed that the use of epoxy-based coatings is suitable for metal structures in the open air. In closed rooms the epoxy intumescent coating should not be used because at high temperature in a fire it ignites with toxic combustion products release.

Fire Protection System

The results of research of fire resistance of steel air ducts with the combined system of fire protection in the conditions of fire influence according to the standard temperature regime according to DSTU B V.1.1-4 are resulted. Steel air ducts were investigated, in the design of which two fire protection systems were used, in which passive fire protection material material (fiberglass "IPS-T-1000") and reactive fire protection material materials ("Endotherm HT-150" and "Endotherm 250103") were used. The research method is applied, which is based on the provisions of DSTU B V.1.1-16. The essence of this technique is that the samples of steel ducts are installed in the vertical support structure of the furnace and exposed to fire. According to the obtained experimental data, the integrity and thermal insulation capacity of air ducts are evaluated. According to the results of the research, the peculiarities of temperature distribution on the unheated surface of air ducts in the conditions of fire influence and characteristics of fire resistance of steel air ducts with the combined fire protection system are determined. It is shown that the temperature is most important on the unheated surface of the duct near the place of its compaction in the vertical enclosingstructure. The temperature on the surface of the duct at a distance of 325 mm from the enclosing structure is several tens of degrees lower than the temperature on the surface of the duct at a distance of 25 mm from it. The period of time to achieve the loss of thermal insulation capacity of air ducts and the class of their fire resistance, which is EI 45. The direction of further researches which are focused on revealing of dependencesbetween a time interval before achievement of loss of thermal insulation capacity and thickness of layers of the combined system of fire protection for steel air ducts is defined. This detection will determine the optimalparameters of the combined fire protection system for steel air ducts, acceptable to ensure their fire resistance for a wide range of duration of fire exposure at a standard temperature.

Maintenance Plan

The integration of a cost-effective coating management plan into an asset integrity system is essential in ensuring asset longevity. The success of any corrosion management program relies on condition monitoring and quality auditing. Monitoring activities also contribute to maintenance plan feedback ensuring continuous improvement in corrosion management activities. It is recognised that there are many ways to organise and operate successful corrosion management programs, each of which is asset specific and depends on factors such as: Design. Stage in the life cycle. Process conditions. Operational history. AGR defines corrosion management as: “…the part of the overall management system that is concerned with the development, implementation, review and maintenance of the corrosion policy.” AGR corrosion management programs use a combination of risk-based Inspection technologies and traditional restorative maintenance activities. SOLVTM, a unique product from AGR Field Operations, is used for the management of fabric maintenance (surface coatings, insulation, passive fire protection, pipe and cable penetrations).Long-term plans: 5-year plans or longer based on client requirements. Prioritising areas and recommended maintenance intervals. Cost estimates and scope of work. Estimated condition development. Application: Treatment of component surfaces (coatings). Passive fire protection. Quality control. The benefits of the SOLVTM concept can be summarised as: Information regarding condition of maintenance objects. Preparation of fixed price maintenance plan and workpacks. Condition control through survey and audit. Cost control via quantified scope. Maintenance budget inputs for 5-year plan. Documented cost savings of 20–50 % have been realised where SOLVTM has been introduced and been used for long-term corrosion management.

Introduction. The international practice of passive fire protection design, as well as some manufactures of fireproofing products recommend to apply fire proofing substances not only to the main element, whose fire resistance limit is standardized, but also to the elements that do not fall under any fire resistance standards. Various support brackets, pipeline supports (hereinafter — PS), etc. can serve as examples. They are not considered as bearing elements according to SP (Construction Regulations) 2.13130.2020, although they are connected to the structures that have fireproofing applied. It is recommended to apply fireproofing substances to such PS within the range of, at least, 450 mm from the point of attachment to the fireproof structure when the area of the PS cross section exceeds 3,000 mm2. No “supplementary” fireproofing is required by the Russian design and fire protection regulations.The subject of research. A change in the fire resistance limit of steel i-girders, caused by the PS heating, depends on the area of the PS cross section and the location of the point of its attachment.The goal. The goal of the research is to analyze the effect, produced by the area of the cross section and the point of attachment, on the fire resistance limit of fireproof steel i-girders in the course of heating.Materials and methods. ANSYS Workbench 2020 R2 (student version) was applied to perform the numerical simulation.Results. The simulation has shown that the PS, having no fireproofing, influences the fire resistance limit of fireproof structures.Conclusions. Currently available methods of analysis of the fire resistance of steel structures take no account of the fire resistance limit reduction, caused by the heating of the PS that has no fireproofing. The numerical simulation has shown that the fire proofing design must take account of the potential reduction in the fire resistance limit of fireproof structures, exposed to the heated PS that has no fire proofing. The further verification of the effect, produced by the PS, that has no fireproofing, on the time to the limit state of a fireproof steel i-girder requires fire tests and supplementary investigations to evaluate the influence of the PS on the heating of vertical fireproof constructions, including the case of the hydrocarbon fire mode.
