What is the primary cause of intergranular corrosion in stainless steel piping systems? Choose the correct answer: A) Presence of oxygen B) Exposure to high temperatures C) Sensitization of grain boundaries D) Mechanical stress Show Answer Explanation: Intergranular corrosion in stainless steel piping systems is primarily caused by sensitization of grain boundaries due to exposure to certain temperatures during welding or improper heat treatment. 2. Which type of stainless steel is most susceptible to intergranular corrosion? Choose the correct answer: A) 304 stainless steel B) 316 stainless steel C) 321 stainless steel D) 310 stainless steel Show Answer Explanation: 304 stainless steel is more susceptible to intergranular corrosion due to sensitization of grain boundaries, especially after exposure to temperatures within the range of 450°C to 850°C. 3. How can intergranular corrosion in stainless steel piping systems be prevented? Choose the correct answer: A) By applying an anti-corrosive coating B) By using high-purity stainless steel C) By avoiding exposure to oxygen D) By properly controlling welding procedures and heat treatment Show Answer Explanation: Intergranular corrosion can be prevented in stainless steel piping systems by properly controlling welding procedures and heat treatment to avoid sensitization of grain boundaries.

Intergranular corrosion is a form of corrosion that occurs preferentially along grain boundaries of a material, typically due to sensitization or other metallurgical changes.What causes Intergranular Corrosion in piping systems? IGC is commonly caused by sensitization of stainless steels, where chromium carbides precipitate along grain boundaries, depleting chromium in the surrounding areas and making them susceptible to corrosion.How can sensitization lead to Intergranular Corrosion? Sensitization occurs when stainless steel is heated in a temperature range (around 450-850°C), causing chromium carbides to precipitate at grain boundaries, reducing the alloy's corrosion resistance.Which materials are most susceptible to Intergranular Corrosion? Austenitic stainless steels such as 304, 316, and their variants are particularly susceptible to IGC if not properly heat-treated or if exposed to sensitizing temperatures during welding or processing.How can Intergranular Corrosion be detected in piping systems? IGC can be detected through visual inspection, dye penetrant testing, or by conducting corrosion tests like the ASTM A262 Practice A test for detecting susceptibility to intergranular attack.What are the consequences of Intergranular Corrosion in piping? It can lead to premature failure of piping systems, especially in critical applications where corrosion resistance is essential for structural integrity and safety.How can Intergranular Corrosion be prevented in piping systems? Prevention methods include using low-carbon variants of stainless steel, applying post-weld heat treatment, choosing appropriate welding procedures, and avoiding sensitizing temperatures during fabrication.What are the standards or guidelines related to Intergranular Corrosion testing? ASTM A262 is a widely recognized standard for detecting susceptibility to intergranular attack in austenitic stainless steels.Can Intergranular Corrosion occur in non-stainless steels? Yes, although less common, it can occur in other alloys where grain boundary precipitation of detrimental phases reduces corrosion resistance.Is Intergranular Corrosion reversible once it starts in piping systems? Once intergranular corrosion initiates, it typically progresses and is not reversible without corrective measures such as repair or replacement of affected components. 12 Recommended Courses on Piping Engineering Complete Piping Engineering CourseBasics of Piping EngineeringPiping Layout EngineeringPiping Material EngineeringPiping Stress AnalysisPiping Material Specifications(PMS)Piping Material Requisitions (MR)Pipe Thickness Calculations: ASME B 31.1, 31.12, 31.3Piping Deliverables & Non-DeliverablesPiping Material-Metallurgy: Mechanical Properties & TestingBasic Elements of Piping EngineeringReinforcement Pad Calculations for Pipe Branch Click here to Check all Published Courses: CourseLand Top 20 Recommended Quizzes (Video + Quiz) Piping Codes, Standards, Specifications & Best Practices: Piping Quiz12 Major Difference b/w ASME B31.1 & ASME B31.3: Piping QuizDifference b/w ASME B31.3 & ASME B31.12: Piping QuizWhat is ASTM & What exactly it does: Piping QuizPiping Deliverables & Non-Deliverables: Piping QuizAPI 600: Piping QuizAPI 598: Piping EngineeringHydrogen Induced Cracking: Piping QuizSulphide Stress Corrosion Cracking: Piping QuizStub-in & Stub-on Connections: Piping QuizPipe Inspection: Piping QuizNon-Destructive Testing: Piping QuizDestructive Testing: Piping QuizFerrite Testing: Piping QuizIntergranular Corrosion: IGC: Piping QuizGrain Test: Piping QuizP Number, F numbers & A Numbers: Piping QuizPiping Activities: Piping QuizInch Dia & Inch Meter: Piping QuizKick-off Meeting: Piping Quiz Click here to Check all Published Quizzes: QuizLand Top 10 Detailed Videos Piping Engineering II Scope & Role II Career Options II How to be Piping expert (45 Minutes)Codes, Standards, Specifications & Best Practices II Differences & Advantages (0.5 Hours)Stub-in & Stub-on II Pipe Branch Connections (15 minutes)Metallurgical Testing II Pipe Inspection & Testing (45 minutes)Non-Destructive Testing II Pipe Inspection & Testing (20 Minutes)Piping Deliverables II Non-Deliverables II Piping EngineeringProcess Datasheet II Tank Data Sheet II Pump Data Sheet II Process Engineering (1 Hour)Part-1 II 2Minutes Funda Series II Piping Engineering (1.5 Hours)Part-2 II 2Minutes Funda Series II Piping Engineering (2 Hours)Questions & Answers II Piping Engineering II Set of 100 Q & A II Interview Questions (2 hours) Subscribe to get updates on Published Videos: YouTube Channel
