(1) Carbon steel pipes for high temperature piping (JISG3456) are pipes for piping mainly used at temperatures exceeding 350 ° C. (2) Alloy steel pipes for piping (JISG3458) are mainly for high temperature piping. (3)Steel pipes for low temperature pipes (JISG3460) are for pipes with particularly low temperatures below freezing. (4)Carbon steel pipes for pressure piping (JISG3454) are pipes for pressure piping used at 350 ° C or lower (marked with *). Those in thickness () are standards for pressure piping pipes only. | ||||||||||||||||
