Heat Conduction Performance Orbital Welding Tube To Tube Sheet 1mm

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.
