Ultrasonic measurements were then carried out on the outer surface of the pipe to provide the residual stress and the wall thickness. This ultrasonic sensor can therefore monitor...

... ABSTRACT The paper examines the effects of, corrosion induced, wall-thinning on buckling of torispherical, hemispherical and ellipsoidal domed closures. It is assumed that the wall is corroded on outside, only. The ratio of corroded wall thickness, t c , to non-corroded thickness, t, is varied...

..., and method to calculate SCF from FE results is introduced, then models bearing forces in two directions (0° and 45°) with different parameters (the angel between the bracing and tower, the diameter and wall thickness of the bracing, the wall thickness of tower) are calculated using shell element, in this way...
