ASTM A106:
ASTM A106 is a standard specification for carbon steel seamless pipe suitable for high temperature and pressure service conditions.
A106 pipes are usually used to transport high-temperature fluids, such as water vapor, air, gas and oil products, and are widely used in the chemical, petroleum, natural gas and power industries.
A106 pipes are divided into three grades: A, B, and C, which represent different mechanical performance requirements.
ASTM A672:
ASTM A672 is a standard specification for arc welded steel pipe suitable for low to moderate temperature and high pressure service conditions.
A672 pipes are usually used to transport low-temperature fluids, such as liquid nitrogen, liquid oxygen, liquid argon, etc., and are widely used in liquefied natural gas, chemical, pharmaceutical and other industries.
A672 pipe is divided into multiple grades, each grade has specific chemical composition and mechanical performance requirements, such as C60, C65, C70, etc.
