What is black pvc pipe made of ?
Answers:
I've plumbed with all manner of pipe, but never seen black PVC. I think you're mistaking it for ABS (Acrylonitrile-Butadiene-Styre... if it's rigid or Polyethylene if it's flexible. PVC (Poly-Vinyl-Chloride) is generally used in plumbing for pressure handling situations or CPVC for high heat areas and pressure. ABS is for drainage only. If it's a pressure line, don't use ABS, it's not rated for it.
The glues for both are different as well. If you are mating ABS to PVC, it can be done, but you'll need what's called transition cement.
Poly pipe is generally joined by using insert fittings, but some types can be heat fused, such as that used in loops for ground source heat pumps. ( that was our winter biz)

You may be confusing it with ABS piping used for sewer and other drain systems. If you are using ABS be advised that you need ABS cement and not PVC cement.
