Astm Standard Dn80 Dn100 Thickness Galvanized Carbon Steel Pipe
Galvanized pipe ordered under this specifification shall be coated with zinc inside and outside by the hot-dip process.
The zinc used for the coating shall be any grade of zinc conforming to Specifification B6. Weight (Mass) per Unit Area of Coating—The weight
(mass) per unit area of zinc coating shall be not less than 1.8 oz/ft2 [0.55 kg/m2 ] as determined from the average results of the two specimens taken for test in the manner prescribed in 17.5 and not less than 1.6 oz/ft2 [0.49 kg/m2 ] for each of these specimens. The weight (mass) per unit area of coating, ex pressed in ounces per square foot [kilograms per square metre] shall be calculated by dividing the total weight (mass) of zinc, inside plus outside, by the total area, inside plus outside, of the surface coated. Each specimen shall have not less than 1.3 oz/ft2 [0.40 kg/m2 ] of zinc coating on each surface, calculated by dividing the total weight (mass) of zinc on the given surface (outside or inside) by the area of the surface coated (outside or inside).
The alloy layer is integrated with pure zinc layer and steel tube matrix, so it has strong corrosion resistance.
Hot dip galvanized steel pipe is widely used in construction, machinery, coal mine, chemical industry, electric power, railway vehicles, automobile industry, roads, Bridges, containers, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery and other manufacturing industries.Astm a53 standard The dimensionless designators NPS (nominal pipe size) [DN(diameter nominal)] have been substituted in this specifification for such traditional terms as “nominal diameter,” “size,” and “nominal size.”The term nominal wall thickness has been assigned for the purpose of convenient designation, existing in name only, and is used to distinguish it from the actual wall thickness, which may vary over or under the nominal wall thickness.
