Here's a good article explaining reducer placement / orientation at pump suctions, and why the used to be confusion around it.

Eccentric reducers and straight runs of pipe at pump suction

The placement of reducers at pumps - Flat on top / flat on bottom, is dependent on whether the liquid source is above or below the pump.

Supports

It is recommended to provide adjustable type supports in suction and discharge piping for pump alignment purpose.

Y-type strainers

In order to improve access for cleaning, Y-type strainers for horizontal suction pipe should be installed pointing downwards or at an angle of maximum 45 deg (check bolt holes quantity) from vertical. Install Y-type strainer away from the pump if located on vertical suction pipe.

Can't forget about a pump's vibration and the effect on adjoing piping. I recently completed a project that involved the evaluating the repeated failure of airlines supporting a solenoid for AOV control. The repeated failure caused the AOV to change positions and introduce system transients. Copper air tubing supporting the solenoid seemed to be right in resonance with the system vibration.

Turned out the fluid pulsations from a 3-piston positive displacement pump (75 gpm @ 2100 psi) were shaking the system.

Ended up replacing the copper air tubing with a short Sch 80 threaded stainless nipple. Quick fix mitigated failures the plant had been living with for years. Always amazed how the simplest fixes can have the biggest impact.
