摘要
The specific features of the procedures for heat-exchanging tubes assembly and fixation in the tube sheets of the power equipment heat-exchanging sections are set out, disadvantages of the existing procedure and the problems of joint quality control due to contact welding are noted. The approaches to assess the pressed joint quality are proposed. The calculation dependences to determine the joint tension considering the fixation procedure features. (C) 2020 Elsevier Ltd.
