ASTM A671 CC65 cryogenic pipe is a cryogenic steel pipe manufactured using the electrofusion welding (EFW) process. It is mainly used to transport fluid media in low-temperature environments. It has good low-temperature toughness and corrosion resistance and can meet engineering needs under low-temperature conditions.
GNEE's LTCS pipe has medium strength and toughness down to -50°F (-46°C). And A671 Gr CC65 EFW welded pipe is stocked in standard sizes from 1/2NB to 36NB. A671 Gr CC65 pipe is available in sizes 5, 10, 40, 80, 80S, 160, XXS and XS. In terms of mechanical properties, the design yield strength of ASTM A671 CC65 grade electrofusion welded pipe is 240N/mm2, and the tensile strength is between 450-585N/mm2.
