Type F: Welded Long Seam Pipe (Furnace Butt Welded Pipe). This type of pipe is commonly used for general low-pressure transportation systems such as water, gas, and heating systems. The pipe is manufactured by furnace welding.
Type E: Electric Resistance Welded Pipe. This pipe is also used for general low-pressure conveying systems and is manufactured by resistance welding for structural purposes and water supply systems.
Type S: Seamless Pipe. This pipe has high strength and corrosion resistance and is suitable for demanding piping systems such as flanged connections and high pressure applications.
ASTM A106 standard pipe is categorized into the following grades:
Grade A: For general technical applications, including low and high temperature service.
Grade B: For high-temperature and high-pressure service, such as piping systems for oil, gas, and power plants.
Grade C: Similar to Grade B, but requires uniform chemical composition and mechanical properties.
ASTM A333 standard pipe is categorized into several grades based on temperature rating and is primarily used for low-temperature service:
Grade 1: Suitable for cooling equipment and cryogenic applications.
Grade 3: Suitable for low-temperature service with good low-temperature impact toughness.
Grade 6: The most commonly used material for cryogenic piping, suitable for the transportation of cryogenic fluids such as liquid nitrogen, liquid oxygen and liquid natural gas.
Grade 7: Cryogenic service, similar to Grade 6, but requires lower carbon content.
Grade 9: Cryogenic service with higher strength and corrosion resistance.
Grade 11: Cryogenic service with excellent weldability.
Grade 12: Cryogenic service with improved strength and corrosion resistance.
Grade 22: Low temperature service with higher strength and corrosion resistance.
ASTM A53 is mainly used for general low-pressure transportation systems and is available in a wide range of different pipe types.
ASTM A106 is mainly used for high temperature and high pressure service and is available in different grades to meet different technical and application requirements.
ASTM A333 is primarily used for low temperature service and is available in a number of different tube grades to suit different temperature ratings and applications.
