Multiple Choice

In dry chemical systems, which pipe material is allowed?

Explanation:
Dry chemical piping must handle abrasive powder flow, be strong enough for high-velocity air, and not react with the chemicals used. Galvanized steel pipe meets these needs: it’s durable, resistant to abrasion, and widely approved for dry chemical distribution, with good static-dissipation properties to reduce spark risk during powder transport. Copper can corrode or react with some powders, and plastics like PEX or PVC aren’t typically rated for the chemical exposure, abrasion, or cleaning requirements of dry chemical systems. For these reasons, galvanized steel is the material allowed.
