Damages in Master Oil Pipeline

Abstract

This paper is an approach to the study of chemical causes responsible for deep damages in oil pipeline in the last few years. These phenomena are responsible for significant direct and indirect economical enterprise loses and cause extensive environmental damage along thetrace. Leaning on laboratory and field tests about fluid properties, characteristic of surrendersoils and pipeline state, performed by several recognize national a foreign institutions the physicochemical causes of the damages, basic corrosion mechanism and main wear direction were proposed. It‘s quite evident the under deposit localized corrosion phenomenon with lowor medium penetration degree, along the tube bottom for firsts 30 km of the installation. Continuous emulsified water segregation from oil phase becomes the main cause of the strongmetal losses. This study followed by technological, mechanical and anti-corrosion evaluations will allow to fine proper solutions for this problem.
