The effect of Acetobacter sp. and a sulfate-reducing bacterial consortium from ethanol fuel environments on fatigue crack propagation in pipeline and storage tank steels
This paper evaluates the effects of microbiologically influenced corrosion (MIC) on fatigue-crack growth of candidate materials useful in expanding bio-ethanol usage, including a storage-tank steel (ASTM A36) and two pipeline steels (API 5L X52 and X70). The microbiological species sampled and cultivated from an ethanol fuel production stream are responsible for both acetic acid and hydrogen su...
متن کاملبررسی بازدارندگی مونواتیلن گلایکول بر خوردگیco2/h2s فولاد api 5l x52
مونواتیلن گلایکول در خطوط لوله جریانی و انتقال گاز چند فازی مرطوب به منظور جلوگیری از تشکیل هیدرات و کنترل خوردگی به کار می رود. در این پژوهش، عملکرد و بازدارندگی مونواتیلن گلایکول بر خوردگی فولاد api 5l x52 در محلول 1 درصد وزنی نمک nacl اشباع شده با گاز co2 در غلظت های مختلفh2s به وسیله آزمون های الکتروشیمیایی پلاریزاسیون و امپدانس مورد بررسی قرار گرفت. همچنین اثر دما به عنوان پارامتر تأثیرگذا...
Corrosion Inhibition of API 5L Carbon Steel by Nettle Leaves Hydroalcoholic Extract in a 0.5 M H2SO4 Solution
In this work, electrochemical methods such as Tafel polarization and electrochemical impedance spectroscopy (EIS) were used to study the inhibition efficiency of Nettle leaves hydroalcoholic extract as a green corrosion inhibitor of API 5L carbon steel in 0.5 M H2SO4 solution. The results showed that the inhibition efficiency was increased with increasing the concentration of the extract and th...
متن کاملThe Effect of Hydrogen Content and Welding Conditions on the Hydrogen Induced Cracking of the API X70 Steel Weld
In this study, first,diffusible hydrogen of cellulosic electrode E8010-P1 and low hydrogen electrode E8018-G was measured by mercury displacement method according to ISO3690. Then,the effect of preheating and post-heating on the sensitivity to hydrogen inducedcold cracking in welding of 18mm API5L X70 steel with these electrodes was investigated according to ISO17642-2. The results of visual in...
