ASTM A333/334 Gr 6 Steel Pipe

ASTM A333 and ASTM A334 are both specifications for seamless and welded carbon and alloy steel pipes used for low-temperature service. Specifically, ASTM A333 covers a range of steel grades suitable for temperatures as low as -50°F (-45°C), while ASTM A334 is intended for temperatures as low as -150°F (-101°C).

introduction
ASTM A333 and ASTM A334 are standards for seamless and welded carbon and alloy steel pipe for cryogenic environments. These steel pipes have excellent corrosion resistance and are suitable for applications such as cryogenic pressure vessels and heat exchangers in the ambient range of -45°C to -195°C.
The number of steel pipe grades in the ASTM A333 and ASTM A334 standards is different. The ASTM A334 standard has 7 grades: Grade 1, Grade 3, Grade 6, Grade 7, Grade 8, Grade 9, and Grade 11; There are 9 grades in the ASTM A333 standard: Level 1, Level 3, Level 4, Level 6, Level 7, Level 8, Level 9, Level 10, Level 11. Of these grades, Grades 3 and 6 are the most commonly used grades specified in ASTM A333 and ASTM A334.
ASTM A333 and ASTM A334 standards are mainly developed for harsh and critical engineering applications. They can be mainly used in production, washing, purification, desulfurization, degreasing and other processes, as well as in low-temperature cold storage, pipelines for transporting low-temperature liquefied gas, and deep-seated liquefied petroleum gas. In applications such as cold separation equipment and air separation equipment. In addition, these steel pipes are often used in the manufacture of components for the pharmaceutical industry.
