[MW:10069] Need clarification about API 1104

Dear all,
 

API 1104 Clause No. 6.2.2 (e) mentions about the 'Pipe wall thickness grouping' as an essential variable.
 
If we have a requirement of welding a sleeve on Pipe (as in-service weld), do we need to consider the Sleeve thickness as an essential variable?
 
I believe API 1104 code is silent about the Sleeve thickness.
 
Please guide.
 
 
 Thanks and Regards,
