Steel Pipeline Failure Prevention
Introduction The reliability and durability of steel pipeline infrastructure are increasingly threatened by complex degradation mechanisms. As these systems operate under demanding conditions, understanding the root causes of material deterioration becomes crucial for safety and performance. This study investigates the primary factors leading to pipeline failures, focusing on selective corrosion and erosion. By integrating macroscopic analysis, corrosion testing, microscopic examination, tensile strength testing, and finite element method (FEM) modeling, the research aims to uncover the mechanisms behind structural weaknesses. The findings provide insights into both localized and system-wide damage, offering a foundation for developing preventive maintenance and design strategies. Selective Corrosion in Heat-Affected Zones Selective corrosion, particularly in the heat-affected zones (HAZs) of longitudinal welds, emerged as the primary degradation mechanism affecting steel pipe...
