Particles emitting inside the pipe instead emit outside the geometry.
( Geometry has solidify modifier )

How to control this

İt can be face orientation, at edit mode select all faces and press alt+n, flip normals, maybe it can solve your problem

[GK00005 (Gajanan)]

Checked that in first place, normals are correct faced out side

[Umut_Islam_Falah]

flip them, it worked for me.

[Umut_Islam_Falah]

you can just add collusion for passing particles
