Product NOUN interpretation: Black Steel Pipe

Black steel pipe is different from galvanized pipe because it is uncoated. The dark color comes from the iron-oxide formed on its surface during manufacturing. The primary purpose of black steel pipe is to carry propane or natural gas into residential homes and commercial buildings. The pipe is manufactured without a seam, making it a better pipe to carry gas. The black steel pipe is also used for fire sprinkler systems because it is more fire-resistant than galvanized pipe.

Black Lacquer Coat

The minimum wall thickness at any point shall not be more than 12.5% under the nominal wall thickness specified.
Permissible Variations in Outside Diameter NPS 11/2″ and under: ± 1/64” NPS 2″ and over: ± 1%
Permissible Variations Weight Per Foot – Pipe shall not vary more than ± 10% from the standard specified.

Galvanizing: The average weight of zinc coating shall be not less than 1.8 oz. per sq. ft. of surface (inside and outside) and not less than 1.6 oz. per sq ft. The dimensions and weights furnished under this specification are in agreement with the standardized dimensions and weights specified in ASME B 36.10.

Product NOUN interpretation: Galvanized Steel Pipe
Galvanized Steel pipe is covered with a zinc material to make the steel pipe more resistant to corrosion.The primary use of galvanized steel pipe is to carry water to homes and commercial buildings.The zinc also prevents the buildup of mineral deposits that can clog the water line. Galvanized pipe is commonly used as scaffolding frames because of its resistance to corrosion.
