You can not do it just with SW. What you need is add in called SPI sheet metal works. It is installed inside SW and it is designed specially for the pipes.

you can get flat patterns if you models is developed as sheet metal parts
when cutting notches make sure your cuts are normal cuts, this will allow continuity to your flat patterns
