Research on Cold-drawing Deformation Process for UNS N08825 Inconel Seamless Steel Tube
Abstract：The finite element（FE）method is used to simulate the deformation courses of three different deformation processes for the small-sized UNS N08825 inconel seamless steel tube，based on which，relevant elements associated with the cold-drawing process are analyzed，including distributions of the stress，the strain and the metal flow speed， and the changes of wall thickness before and after the cold-drawing […]
Introduction to Finned Tube Products
1. Basic Concept Finned tubes are high-efficiency heat exchange components designed to enhance heat transfer by expanding the surface area of the base tube. They are widely used in energy, chemical, HVAC, and other industries. Their core principle lies in leveraging fins to amplify heat transfer area, thereby improving thermal exchange efficiency between fluids and […]
