Nickel and Nickel cobalt alloy tube (ASME SB -622 or SB-626) vs copper tube

[ed2009]

Could anybody tell the difference if the Nickel and Nickel cobalt alloy tubes (ASME SB-622 or SB626) are used on the hydrogen cooler instead of copper tube? The fluid in the shell side is hydrogen while the tube side is lake water. Thanks.

Dear ed2009,

Check the temperature limits of Cu and Ni-Co.

Regards.
