ASTM A333 Low Temperature Pipe is a type of carbon and alloy Steel Pipe designed to be used in low-temperature applications.
They are low- to medium-carbon (0.20 to 0.30%), high-manganese (0.70 to 1.60%), silicon (0.15 to 0.60%) steels, which have a fine-grain structure with uniform carbide dispersion.
ASTM A333 specification covers nominal (average) wall seamless and welded carbon and alloy steel pipe intended for use at low temperatures down to -45°C (-50°F). A333 pipe is furnished to nine different grades designated by numbers 1, 3, 4, 6, 7, 8, 9, 10, & 11.
The ASTM A333 Low Temperature Pipe is commonly used in industries such as power generation, refineries, petrochemical plants, and other process piping applications where low-temperature service is required. The material composition of the pipe includes carbon, manganese, phosphorus, sulfur, silicon, nickel, and chromium, among others, with the addition of low-temperature heat treatment to ensure the pipe's toughness and impact strength at low temperatures.
ASTM A333 Low Temperature Pipe is available in several sizes ranging from 1/4" to 42", with various wall thickness schedules such as SCH 10, SCH 20, SCH 40, SCH STD, SCH 80, SCH XS to SCH 160, and SCH XXS. The lengths can be single random, double random, or 20 ft and 40 ft, and the pipe ends types can be plain or beveled.

*For Grade 1 and 6, each reduction of 0.01% C below 0.30%, an increase of 0.05 % Mn above 1.06 % would be permitted to a max. of 1.35%.
*For Grade 6, the limit for columbium may be increased up to 0.05 % on heat analysis and 0.06 % on product analysis.
*Generally, the carbon equivalent C.E = [C + Mn/6 + (Cr + Mo + V)/5 + (Ni + Cu)/15] shall not exceed 0.43% by heat analysis.
