Abstract Different severe corrosions are found at the damaged point of anticorrosive coating on natural gas pipelines, even though cathodic protection (CP) potential is between −0.85 and −1.15 V. Therefore, there totally 168 buried steel specimens (BSSs) 28 soil samples points that taken out in situ then analyzed lab to assess CP effectiveness. First, status simulated by BSSs points, corrosion products microscopically. Second, rates testing calculated weight‐loss method perform quantitative...
AbstractPipeline corrosion induced by sulfate-reducing bacteria (SRB) is particularly severe during the hydraulic fracturing technology in shale gas exploitation. To investigate evolution of beneath SRB biofilms, 49-day experiments were performed with and without SRB. The weight loss experiment demonstrated that Blank group was mitigated product film. In contrast, exhibited an initial inhibitory phase followed exacerbation. Scanning electron microscopy (SEM) revealed stratification group,...
Abstract Reboilers are pivotal in the process of condensate oil stabilization, playing a significant role reducing vapor pressure to ensure product stability. The operational milieu reboiler tube bundles is marked by extremities—high temperatures, elevated salinity, and presence dissolved oxygen—rendering them vulnerable stress corrosion cracking. Such conditions can precipitate untimely degradation disrupt production schedules. Addressing this, our research employed electrochemical noise...
Corrosion perforation of wet gas pipelines occurs frequently, threatening the safe production on fields and bringing huge economic losses. Therefore, need to use a suitable corrosion prediction model predict rate along pipeline anticipate risk. However, current models have problems such as large errors inaccurate predictions. This paper compares four common combines these with OLGA multiphase flow simulation calculations condition same under three different conditions. Finally, it...
This paper studies the corrosion mechanism of weld seam submarine pipeline’s spool. The types and causes inner tube are simulated by EDX XRD analysis on-site pipe products, combined with OLGA Software simulation pipeline flow pattern. tensile testing, impact testing hardness were carried out on base metal tester, pendulum tester Brinell to analyze mechanical properties weld; microstructural difference between analyzed optical microscopy; results show that liquid phase rate along line is...
Abstract With the development of high sour gas fields, failure gathering pipelines in field caused by corrosion is becoming more serious. So it important to select effective detection methods detect defects insure safety operation pipelines. In view characteristics that uniform corrosion, pitting, hydrogen induced cracking and stress occur easily adaptability three external techniques which include transient electromagnetic method, metal magnetic memory testing ultrasonic guided wave...
