The JIS G3460 standard specifies steel pipes for pipelines at extremely low temperatures at or below freezing. The pipes should be made of fine-grained killed steel.
The main grades of JIS G3460 steel pipes include STPL380, STPL450, STPL690.
STPL380 pipes should be seamless or electric resistance welded pipes, and STPL450 and STPL690 pipes should be seamless pipes.
