[MW:5465] two halve pipe for Branch connection

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
