A333: ASTM A333 is designed for cryogenic applications. It covers seamless and welded steel pipe for cryogenic service (-50°F [-45°C]) applications. These pipes are commonly used in industrial and commercial refrigeration, gas processing and other cryogenic applications.
A106: ASTM A106 is a general specification covering seamless carbon steel pipe for high temperature applications. Suitable for applications involving high-temperature fluids and gases such as power generation, petrochemicals, and refineries.
temperature range:
A333: A333 pipe is designed to operate in cryogenic environments and can withstand temperatures as low as -50°F (-45°C). They are ideally suited for applications where low temperature impact toughness is critical.
A106: A106 pipe is suitable for higher temperature applications. The standard specifies different temperature ranges depending on the type (grade) of steel used. For example, A106 Grade B is suitable for a temperature range of -20°F to 650°F (-29°C to 343°C).
score:
A333: The A333 is divided into several classes, with Class 6 being most commonly used for cryogenic services. Other grades, such as Grades 1 and 3, have specific shock testing requirements and are suitable for lower temperatures.
A106: A106 is divided into A, B and C grades. Grade B is the most commonly used grade and provides good tensile and yield strength for high temperature applications.
Impact test:
A333: A333 requires low-temperature impact testing to ensure the material's ability to withstand brittle fracture. This is especially important in applications where pipes are exposed to sub-zero conditions.
A106: A106 generally does not require impact testing as it is suitable for high temperature environments where the risk of brittle fracture is low.
