USE THIS NOTE IN B 2.3 WILL EASE YOUR QUALIFICATION.
Note: Filling the test section with water and allowing water to flow
through the test section while the test joint is being made has been
shown to produce thermal conditions equivalent to or more severe
than any typical in-service welding application (see Figure B-2).
Procedures qualified under these conditions are therefore suitable for
any typical in-service application. Other media (e.g., motor oil) may
be used to simulate less severe thermal conditions.

Dear Experts,
We are actually in the process of making WPS for Hot Tapping . in this context while referring to API 1104 , unable to interpret the below paragraph from API 1104 In Service welding .
Kindly help in understanding
B.2.3.1.2 Pipeline Operating Conditions
For in-service welds, an increase in the severity of the pipeline operating conditions (in terms of weld cooling rates)
above the group qualified constitutes an essential variable.
Thanks in advance
