[MW:5698] two halve pipe for Branch connection

In my opinion , yes, refer para 304.3.5

For branch connections which do not meet the requirements of para. 304.3.1(b), integral reinforcement, complete encirclement reinforcement, or other means of reinforcement should be considered.

a typical detail from one of the client std is appended below.

Dear all,

Regarding reinforcement of piping branch connection As per ASME B 31.3
para.304.3

Can we use two halves pipe for reinforcement of header pipe considering the actual Dh/Dt ratio is not fulfilling the requirements para 304.3.1(b).
Does ASME B 31.3 shall allowed these type of connection?

The same type branching connection mostly used in HOT tapping procedure.

Thanks in advance

Vinayak
