Features of tank car testing for dangerous cargoes transportation

Abstract

Abstract The experience of the operation of rail transport shows that a significant part of emergency situations with significant negative environmental consequences are related to tank cars carrying liquid goods of a wide range, including liquefied gas, petroleum products, concentrated acids, toxic and explosive products of chemical origin. The article presents the peculiarities and result of carrying out of the corresponding tests. In order to address the question of the possibility of further safe operation of tank cars in the over-term period, their technical diagnostics and control tests are carried out. In this case, the control of the technical condition includes visual inspection of the tank wagon, measurements of the thickness of the metal at the control points of the boiler and the frame of the car, conducting of the magnetopowder, ultrasonic and acoustic emission control of the bearing metal constructions. Control tests include static vertical load tests, test for a low cyclic load by boiler pressure, typical, resource shock tests, and possible emergencies testing.
