Must the inner diameter of the pipes between the serve and receive buckets be the same?

Must the inner diameter of the pipes between the serve and receive buckets be the same? Will there be any issue with the ball getting stuck if there’s a slight difference?
The wall thickness of the 6D elbow on the pipeline is 2 mm greater than that of the pipe, and the inner diameter at the elbow is smaller – could this lead to ball jamming?
Isn’t the diameter of a ball usually only 2/3 of its inner diameter?
These days, pigs are used – rubber sleeve type pigs, whose outer diameter is larger than the inner diameter of the pipe
Thank you. Can the inner diameters of the pipelines between the serve and receive buckets be different, or must they be identical? Is there any regulatory basis for this?
Is the reason you say it’s not certain the ball getting stuck caused by the change in inner diameter?
Is that so? I’m talking about the ball test – after cleaning with a pig, shouldn’t a ball test still be carried out?
Balls are divided into hairy pigs, sponge pigs, product pigs, etc. For sponges, anything goes; they have a great degree of deformability. The other two won’t work; piglets are prone to getting stuck, and pigs with lip edges also don’t work
