Flange clarification required

Flange clarification required

Flange clarification required

Dears ,

As my project 2500 gpm 9.7 bar centrifugal fire pump with ductile iron piping PN16 pressure rating.
in pump nozzle flange standard ANSI 125# B 16.1
all valves flange standard ANSI 150# B 16.5

Ductile iron flange standard PN16 or BSEN standard.

Since I need some clarification on below mentioned threads.

ANSI 125# B 16.1 flange dimension standard and flange hole, bolt size same with ANSI 150# B 16.5 flange
Ductile flanged piping possible to customize on ANSI 150# B 16.5 flange ?>

or else give any possible modification solution.

Thanks ,

Also add the flange face to your description. FF or RF. Iron flanges tend to be FF so you need valve flanges to match.

Remember - More details = better answers
