Abstract

The article focuses on the original author's development – the flexible liner for a rail tank car that allows reducing the risk of leakage of hazardous liquid cargos (in particular crude oil or petroleum products) during their transportation by rail. Application of the liner allows ensuring hermetical containment of a tank car even if a barrel has any minor defects, excludes a contact of cargo with tank walls, which leads to increase in the security of hazardous liquid cargo transportation. This original development enables ensuring the safety and security of hazardous cargo transportation and minimizing its impact on the environment. The liner can also be used for increasing the service life of a rail tank car and reducing the costs of its maintenance.

Highlights

For the rail transportation of third hazard class cargos such as crude oil and petroleum products, rail tank cars are used [1]
The rail tank car fleet involved in transportation of crude oil and petroleum products, which contains more than 275 thousand units, is currently private, it is complicated to control the used tank cars for correspondence to regulatory requirements
In 2011, 126.4 million tons of oil and petroleum products was shipped on domestic routes

Summary

Introduction

For the rail transportation of third hazard class cargos such as crude oil and petroleum products, rail tank cars are used [1]. The total volume of transportation of oil and petroleum products by open joint-stock company "Russian Railways" amounted to 250.3 million tons in 2013. More than 78% of incidents during transportation of hazardous cargos realized by open joint stock company "Russian Railways" is associated with using tank cars. The statistical reporting analysis carried out by the authors shows that in recent years there has been a consistently high number of incidents associated with the transportation of oil and petroleum products on the Far Eastern Railway (Figure 1). Thereto, the reasons of 85% of such incidents are the leakages through the drain device or barrel defects In this regard, it seems relevant to develop special technical means to eliminate and prevent leakages from rail tank cars
