Find the intersection point between two spline

Hello, I want to know if it’s possible to find the intersection point between two splines to spawn a mesh at this possition.

I need this to create pipe system with T section et cross section. For the T section I need to kno how to connect to spline and for the cross section is more detecting the intersection of to spline and just spawn the cross part over the spline to hide this.

Thx for your help
