We are using flanged branching in case of spec ….
Stainless steel Drinking water distribution Piping, T (max) =40C,
P (max) =800kPag, CA=Nil, Hyd.Test Pr=949kPag, Cl150.

We are using normal branching in case of spec ….
Carbon Steel Liquor Piping, T (max) =150C, P (max) =1610kPag, CA=1.5, Hyd.Test Pr=2566kPag, Cl150.

Why the connections are different?

Thanks…..
