True or False: Black steel pipe and fittings are permitted for non-corrosive atmospheres in dry chemical systems.

Explanation:
Piping materials for dry chemical systems are chosen based on the environment’s tendency to cause corrosion. In a non-corrosive atmosphere, black steel (carbon steel) piping and fittings are acceptable because there’s little risk of rust or chemical attack on the steel, so you get good strength and cost-efficiency. If there is any chance of moisture or corrosive vapors, protective options like galvanized steel or coatings are used to resist corrosion. So, in non-corrosive environments, using black steel pipe and fittings is permitted.
