ASTM A333 Grade 6 Pipe
In low temperature services industries, ASTM A333 Grade 6 pipe is one of the most used pipe.
ASTM A333 Standard Specification Scope
ASTM A333 is the standard specification for seamless and welded steel pipe for application in low temperature services and other applications with the required notch toughness.
Manufacturing types
The standards includes manufacturing types in welding (ERW) and seamless. Material covers carbon and alloy steels.
How many grades that included in ASTM A333 specificatoin?
There are total 9 grades in this standard, Grade 1, 3, 4, 6, 7, 8, 9, 10 and Grade 11.
Dimensions and sizes schedule
The pipe complied to Nominal Dimension standard ASME B36.10M. (NPS or outside diameter and schedule number of average thicknes)
Meanwhile, some product sizes may not be available under the ASTM A333 standard, as heavier wall thickness have an harmful on impact properties. If client have special requirement, please consult the supplementary specification in ASTM A333.

Differences between each grades
As we know ASTM A333/A333M pipe could in be seamless or welded. But when to use seamless and in any situation to used welded type?
In case of ASTM A333 Grade 4 steel pipe, it shall be made by the seamless process.
If welding process in EFW or ERW with filler metal added, and fabricated of pressure vessel quality plates.
