It's unclear what type of spring is used and how that spring is attached to the pipes. Your figure makes me think the pipes are modeled with shells. Maybe that's not the case. But anyway, you can get forces and moments at a cross-section using *DATABASE_CROSS_SECTION_PLANE (defines location of cross-section) and *DATABASE_SECFORC (defines time interval for output of cross-section data to secforc).
