RISDetection of Cracks in 25Cr35NiNb Ethylene Pyrolysis Furnace Tubes by Metal Magnetic Memory Technique
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Cracking in 25Cr35NiNb pyrolysis furnace tubes is difficult to detect in engineering production. This paper presents a metal magnetic memory technique for inspecting cracks. To verify the effectiveness of the proposed ...
Improved Oxidation, Carburization Resistance and Creep Strength of Ethylene Pyrolysis Furnace Tubes at 1100 °C Through Aluminum and Tungsten Alloying
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. The oxidation resistance, carburization resistance, and mechanical properties of ethylene pyrolysis furnace tube alloys modified by Al/Al-W alloying were comparatively investigated with conventional alloys using ...
