Great Heat Conduction Performance Tube To Tube Sheet Orbital Welding Tubesheet
Tubesheet is a kind of fitting that drills a hole slightly larger than the outer diameter of the pipe
on the circular steel plate, penetrates the pipe, welds and fixes it. In the calculation of fixed tubesheet,
the axial stress of shell, the axial stress of heat exchange tube and the pull-out force Q between heat
exchange tube and tubesheet are calculated according to various working conditions with temperature
difference.
If one of them cannot meet the strength (or stability) conditions, it is necessary to set expansion joints.
In the strength check calculation of fixed tubesheet, when the tubesheet thickness is determined and
no expansion joint is set, sometimes the tubesheet strength is not enough. After the expansion joint is set,
the tubesheet thickness may meet the requirements.
At this time, expansion joints can also be set to reduce the tubesheet, but it depends on the comprehensive
evaluation of material consumption, manufacturing difficulty, ety and economic effect.
