... the wall thickness of tubing by swaging over a mandrel. A mandrel is used to maintain the inside diameter of a tube during the swaging of its outside diameter, to support thin-wall tubes during reduction in diameter, and to form internal shapes. When extended through the front of the dies, a mandrel...

... inspection of heat-exchanger tubes and boiler tubes often involves the use of a differential bobbin probe, which is inserted into each tube. The probe can be configured to only provide an indication where there is wall thinning, making it an accurate corrosion and erosion inspection tool. In tube and pipe...

... needed on the inner side of a tube bend. Wall thickness of the tubing affects the distribution of tensile and compressive stresses in bending; a thick-wall tube usually bends more readily to a small radius than a thin-wall tube. Table 2 gives the minimum practical inside radii for cold draw bending...
