RE: [MW:10074] Need clarification about API 1104

Sleeve longitudinal welding  & Branch welding will be covered by API 1104 clause 6.2.2.e

 

In Sleeve to Pipe Fillet weld, the wall thickness is not an essential variable according to API 1104 clause B2.2.1.3 Appendix B

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,
