The ASTM A333 Grade 6 seamless steel pipes are intended for low temperature services with minimum design temperature -45°C [-50°F] requiring notch toughness.
They are usually furnished in nominal pipe size (NPS) and nominal wall thickness with schedule numbers in accordance with ASME B36.10M. They are often connected with flanges of ASTM A350 LF2 and butt-weld pipe fittings of ASTM A420 WPL6. Seamless pipes made from ASTM A333 Gr.6 are primarily used for the construction of pipelines in the production of ethylene, propylene, urea, ammonia, and N-P-K compound fertilizer. They may be involved in the scrubber, purification, desulfurization and degreasing processes in oil & gas, petrochemical, coal and pharmaceutical industries.
They can also be used for the fabrication of cryogenic equipment as well as refrigeration houses.
ASTM A333 Grade 6 pipe is commonly used material for low temperature services in above -45℃, with yield strength minimum at 240 Mpa, and tensile strength 415 Mpa.
ASTM A333 Standard Specification Scope
ASTM A333 is the standard specification for seamless and welded steel pipe for application in low temperature services and other applications with the required notch toughness.
