Intergranular Stress Corrosion Cracking

Abstract The general principles of equilibrium grain boundary segregation are applied to form a theory on the possible elimination of intergranular stress corrosion cracking in alpha aluminum bronze in steam. Various possible alloy additions are discussed in relation to their atom size, solubility, and tendency to react with steam. A theoretical selection of beneficial additions is made. Actual test results on several alloys containing a variety of additions are presented, illustrating good agreement of theory and results. The effects of the additions on transgranular ammonia cracking susceptibility are also discussed. A brief history of the application of laboratory results to field testing and actual application to the product is given. 3.7.2

Two sections of a 914mm OD (36 in.) TransCanada (TCPL) gas transmission pipeline (predominantly with 9.14 mm wall thickness) were inspected using an ultrasonic liquid coupled crack detection In-Line Inspection (ILI) tool. One of the objectives of the inspection was to establish the condition of the pipeline sections with a known history of stress-corrosion cracking (SCC). Under test was the practicability of inspecting a gas line using a liquid coupled ILI tool, specifically its ability to detect and size defects deeper than 1 mm and distinguish cracks and crack-like defects from other types of anomalies, such as inclusions and laminations. In order to assess the confidence level of the tool, both sections were inspected in two independent runs and the repeatability of inspection was assessed. Cracks and crack-like defects with depths greater than 12.5% of the wall thickness from both runs were compared and correlation was established to assess repeatability. The accuracy of tool predictions was verified in excavations in both sections. 40 reported features, varying in depths up to over 40% were examined with respect to location, type, and size. Examples of defect patterns are shown to demonstrate the accuracy of the inspection method.

Abstract AMBRONZE 413 is a copper-tin bronze recommended for plater's plates and electrical contact springs. It is relatively immune to stress-corrosion cracking. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: Cu-201.
