The tube heat resistance was examined. The direct tests of rupture strength of five technological variants of tube production for 100 thousand hours were made. The positive results of tests allowed to attestate the technology of tube production on four technological variants and gave the guarantee resolution to the plant on the possibility of heat-resistance guarantee of there tubes. The tubes of one of the technological variants had the reduced heat-resistance and low plasticity. The detailed analysis of technology and equipment allowed to find out the cause of this. The technology improvement of this technological variant will be the theme of the next work Product Description popup.authors popup.nrat_date 2020-04-03 Close
