Hello to all.
What do you thing about this pipe routing for pump suction.
Details:
suction size 4"
line size 8"
Tope=110°C
On suction nozzles are ecc red from 8 to 4"

One pump is working another standby. Temp up to first valve for standby is 50%Tope and after valve Tabm.

This is client request but I already try this and no chance to achieve allowable loads on suction nozzles.

Notes check by stress means minimum. I am just interested for opinion if anybody want to comment this routing especially between pumps. I made routing which works but client just say NO. My routing is on another image.

Pump is piston inline type.

Thanks for comments if somebody want to discus:)
