Carbon Steel Pipe Standards and Grades

Carbon steel pipe is the most common use piping material in different industries served for construction, structural, liquid transmissions for water, oil and gas.


Carbon steel pipe is the most common use piping material in different industries served for construction, structural, liquid transmissions for water, oil and gas. Typical carbon steel pipe material grades in API 5L Grade B, X42 to X70, ASTM A106 B, ASTM A53 B, ASTM A252 Grade 3 and ASTM A333 Grade 6 etc.

Carbon steel pipes are widely used in various applications due to their strength, durability, and cost-effectiveness. They are made primarily from carbon and iron, with varying carbon content that affects their properties.

ASTM A106 Gr. B in Seamless
ASTM A53 Gr. A, B in Seamless, Welded ERW, and Zinc coated, hot-dipped galvanized steel pipe
ASTM A179 Gr. C in Seamless (For seamless cold drawn low carbon steel heat-exchanger and condenser tubes)
ASTM A192 (For seamless carbon steel boiler tubes for high-pressure service)
ASTM A252 (For welded and seamless steel pipe piles)
ASTM A333 GR. 1, 2, 3, 4, 5, 6 (For seamless and welded steel pipe for low-temperature service and other applications with required notch toughness)
ASTM A134 and ASTM A135 (For electric resistance welded ERW steel pipes)
API 5L Pipe, ISO 3183 / API 5L Gr. A, B, X42, X46, X52, X56, X60, X65, X70, X80 in seamless and welded (LSAW, SSAW, ERW) steel pipe, for petroleum and natural gas industries, steel pipe for pipeline transportation systems.
DIN 2440 seamless and welded steel pipes applies to medium-weight tubes suitable for screwing. (DIN2444 Zinc coated steel tubes, for hot galvanizing)
CSZ Z245 Seamless and ERW welded pipe (low-frequency electric welded pipe excluded), SAW steel pipe that intended for oil and gas pipeline systems.
NBR 8261 Cold-Drawn, Cold-form, welded steel pipe, in circular cross-section, square or rectangular, applied to structural purposes.
AWWA C-200 for steel water pipe
