On Thermally Induced Multiple Cracking of a Surface: An Experimental Study
Source abstract
Abstract
An experimental study of the thermally induced surface multiple cracking, on the example of steam superheater collector was carried out. The structure’s perforated area has 3 rows of holes, to which the connection sleeves are welded. On the first stage, the cracks initiate on the inner surface of the perforated area of the collector. These cracks are due to the thermal fatigue, caused by temperature changes at start-stops and by temperature fluctuations during operation. The histograms and cumulative distribution functions of crack lengths and the inclination angles with respect to the axes of fastening pipes holes were obtained. The length of most cracks was less than 2 mm. Also, an important localized damage on the collector inner surface in the form of a partly circumferential crack with a length of 149 mm and with the largest depth of 37.8 mm was observed.
