Question

what type of piping should not be used with compressed air?
o a. copper pipe
o b. aluminum pipe
o c. steel pipe
o d. pvc pipe

Explanation:

PVC (Poly - Vinyl Chloride) is a thermoplastic. Compressed air can generate heat and pressure. PVC pipes may not withstand the high - pressure and heat associated with compressed air systems. They can crack, deform or even release harmful fumes under such conditions. Copper, aluminum and steel pipes are more suitable for compressed air applications due to their higher strength and heat resistance.

Answer:

D. PVC pipe
