it is a flow rate that you mentioned in WPS.
-- qualified PQR with severe condition where cooling rate is high and chances of burn through is high.
that's meaning.

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
