TO THE ISSUE OF FIRE SAFETY AT PRE-TRAINING ON PIPELINES WITH FLAMMABLE LIQUIDS
The paper deals with the issues of fire danger arising in the pre-repair preparation of process pipelines with flammable liquids. The results of the analysis of statistical data on fires in the oil and gas industry. The basic elements of expert-diagnostic maintenance of technological pipelines and the order of preparation for fire repair works are listed. The photo of technological oil product pipelines and the scheme of leakage of the "dead residue" of oil product at the flange connector on the oil product pipeline are presented. The dependences of the mass of flammable liquid released from the pipeline to be prepared for repair on the cross-sectional area of the pipeline, as well as the dependence of the volume of the "dead residue" of oil product in the pipeline sections of different lengths depending on the diameter of the pipeline are determined. The analysis of foreign and domestic regulatory requirements in the field of fire risk reduction of emergency spills of flammable liquids. Various technical solutions aimed at limiting the spreading of flammable liquids and technical devices for self-extinguishing local spills of flammable liquids are considered.
