How to bend a tube?

I want to bend a tube with a radius of 150mm.
I have drawn 3 tubes to form a C shape. I want to combine them into one tube with a radius of 150mm at intersection. In reality, it can be done by a bending machine.

You can also use Pipe with the centerline for a circular cross-section tube.
