Yes,Testing requirement after installing tube to the unit.
Do we have to inspect the individual tube after the tube is attached to tube sheet?
Do we have to specify any special requirements in fabrication of Ta tube to Tube sheet Joint?
Do we have to perform any other test than He Leak test?
Yes the service is corrosive on tube side. My special concern is beacause tube is only 0.015in thick
And also,Is it ok to rolled and expand 0.015in thick tube to tube sheet?
Looking forward for more guidance.
Thanks.
