Double pipe heat exchanger design

[Chiller]

Does anyone have a design method or can lead me to a site for double pipe heat exchangers.
I am specifically looking for the following calculations: -
1) to determine blocking ring/tubesheet thickness.
2) differential expansion stresses on blocking rings and shell & determine whether bellows will be required. Shellside is 3.3barg/10degC whilst tubeside is 119barg/230degC.
3) method of welding/attaching tube to tubesheet.

Many thanks in advance

Hello :

I need some General information (such as appilication , sheel & tube standars,...) about these heat exchanger :

1)double pipe heat exchanger
2)hairpin heat exchanger
3)coaxial pipe heat exchanger

Thanks
