  Corrosion Failure Analysis of Elbow in LPG Desulfurization Unit
  Author(s): Jianwen Z, Guoqing S* and Chuansheng W
  
  The elbow plays a crucial role in changing the flow direction of the medium in pipeline system and is one of the most commonly used pipeline components in the oil and gas transportation. This paper focuses on the corrosive failure mechanism of the elbow of regeneration tower of LPG desulfurization unit in a refinery. Aiming at the failure elbow, based on the macro and micro perspectives, the physical laws of the inner layer of the elbow, including the distribution of corrosion holes and wall thickness, are summarized and analyzed. The further characterization methods were used to study the corrosion mechanism, including mechanical properties, metallographic examination, X-ray diffraction analysis (XRD), scanning electron microscopy (SEM) and energy spectrum analysis (EDS). Taking the thief hole as center, the elbow was divided into 4 rows. It is found that the maximum diameter was 21... View More»
