1. Introduction
Liquid erosion is one type of wear that is the progressive loss of original material from a solid surface due to mechanical interaction between the surface and a fluid in a very small area. This can be further classified into two types: i.e., the cavitation erosion and the liquid impingement erosion. The cavitation erosion is usually caused by the formation and collapse of cavities or bubbles within the liquid. In engineering practice, lots of machines and structural components suffer cavitation damages, which makes cavitation erosion become very active research topic all the time [1–7]. However, the liquid impingement erosion, which originates from the impact by liquid drops or jets, has been rarely reported as the dominated reason [8–10]. Actually, in most of previous failure cases, the liquid impingement erosion often appears together with corrosion [11–16]. In this work, failure analysis of a leaked oil pipeline was carried out. Through careful macroscopic and microscopic observations, the leakage of this pipeline was found to be fully caused by the liquid impingement erosion. The pipeline is made of one kind of low-carbon steel, and its wall thickness is 4.5 mm. The pipeline was located in an underground trench that is covered by cement boards, and had been used for about ten years. In addition, while it was usually empty in the pipeline, some oil with temperature of 80 8C could flow through the pipeline during the period of the equipment maintenance.
