Who is Yasser Kassem? general manager at a petroleum company, graduated from faculty of science, class of 1988 and specialized in chemistry. Started working in oil field in 1990 at chemical laboratory carrying out water & oil analysis, and following up chemical treatments. Few years later, worked in corrosion and cathodic protection. Worked also in water injection, […]
Erosion-Corrosion Likelihood – API RP14-E is not valid in presence of solid particles (sand) – It is not valid in vertical flow (even if it is used as well) – It is not valid for gas systems (where no definite velocity limits are identified). – Alternative models have been proposed (as SalamaModel)/ or typical critical […]
Internal Corrosion in Oil and Gas Production Facilities Before talking about corrosion in oil and gas facilities, we have to define some of the main sections of these facilities: Gathering System and Manifolds Unit – Gather the flowlines that convey the liquid and/or gaseous hydrocarbons coming from production wells. – Send the product, by means […]
Corrosion Corrosion is defined as the destructive attack of a metal by the environment, by chemical or by electrochemical processes (as contrasted with mechanical means such as the erosion of a metal structure by sand in the desert). Corrosion includes conjoint mechanical and chemical action to produce early failure of a load-carrying metal structure, eg. […]

الحماية الكاثودية Cathodic Protection الحماية الكاثودية هي طريقة لمنع التآكل والصدأ عن الأسطح الخارجية للمعدات المعدنية الحديدية المدفونة أو المغمورة بالماء بجعلها أقطاب سالبة من دائرة كهربائية. تستعمل الحماية الكاثودية لحماية خطوط الأنابيب الفولاذية و الخزانات و الهياكل الفولاذية و السفن وأرصفة تحميل النفط البعيدة عن الشواطئ والبطانات المعدنية لأبار النفط. وذلك بجعل الجسم المعدني […]
التآكل – الجزء الثاني البيئات المحتملة للتآكل Corrosion: تقسم البيئات الى 4 أقسام: 1. بيئة لا تسمح بالتآكل: وذلك بغياب الماء المكمني Formation Water أو في الظروف التالية: Water + VCO2 <50 μm/y + pH2S < 0.0035 bar 2. بيئة تحتوي على غاز CO2 . […]
ما هو التآكل Corrosion ما هو التآكل Corrosion: هو عبارة عن تفاعل فيزياوي – كيمياوي مشترك بين المعدن والمحيط مما يؤدي الى حدوث تغييرات وتلف في المعدن. وهو ظاهرة طبيعية ، يجب السيطرة عليها. وتتأثر بالعديد من العوامل وهي أمر يصعب التنبؤ به ولكن العوامل المؤدية اليها واضحة جداً كما أن آثاره عظيمة ومكلفة.

Is oxygen corrosive? Yes. Oxygen is a highly reactive gaseous element. In the presence of steel, the corrosion rate of oxygen doubles for each 30°F rise in temperature. For example, in a boiler system operating at 400 psig and 444°F, the corrosion rate for oxygen is 256 times more reactive than at room temperature. How […]
