Are end fittings necessary at the inlet and outlet of a screw pump? Is it not allowed to weld the pump inlet and outlet directly to the elbow? Is a straight pipe section necessary?

It is due to such requirements that there must be straight pipe sections

A termination must be added at the outlet of the single-screw pump in order to facilitate the removal of the rotor and the replacement of the stator. I’m not sure if there are such requirements for twin-screw and triple-screw systems
