Abstract: Thermal stress is an important factor influencing the strength of a heat exchanger tubesheet. Some studies have indicated that, even in floating-head or U-tube heat exchangers, the thermal stress at the tubesheet is ...

Abstract: Strength calculation for tubesheets in floating-head heat exchangers (FHXs) in current standards is based on analytical theory which assumes that the two tubesheets are symmetrical with same thickness, same material. This ...

Abstract: In this paper, a series of impact tests on S30403 austenitic stainless steel at 20/−196/−269 آ°C were performed to determine the effects of cryogenic temperatures on the material properties. Both base plate and welded ...
