This paper discusses in detail the structural characteristics of U-tube bundle within the heat exchange equipment,puts forward specific solutions during the important links in order to guarantee the manufacturing quality of U-tube bundle effectively.

Analysis for Stress Intensity Factor of Elliptical Surface Crack in U-tube with the Method of Sub-modeling;

Study on Influence Factor of Heat Transfer Performance of the U-tube

Analysis on Leakage Reason of Stainless Steel U-tube Used as Heat Exchanger

The Research and Development of the Experimentation Platform for Measuring U-pipe Pressure;

An experimentation platform for measuring U-pipe pressure designed by myself is introduced.

It is also found that thermal property of greater diameter coaxial pipe heat exchanger is better than U-pipe heat exchanger,howeverΦ65 coaxial pipe is optimum for cost effective.

Experiments on the density wave instability of the high pressure steam water two-phase flow in a U-type tube have been performed within the range of pressure from 4 to 10MPa, mass flux from 450 to 1200 kg/m~2·s, inlet subcooling from 10 to 70℃, and heat flux from 0 to 650 kW/m~2.
