JIS G3454 Carbon Steel Pipes Appearance
The pipe shall be practically straight, and its both ends shall be at a right angle to its axis. The inside and outside surfaces of the pipe shall be well-finished and free form defects that are detrimental to practical use.
JIS G3454 Carbon Steel Pipes Nondestructive Test
The pipe shall be tested in accordance with 9.5 and the resulting hydrostatic characteristic or nondestructive characteristic shall conform to either of the following two. The preference for which of them shall be left to the specification by the purchaser or to the discretion of the manufacturer.
JIS G3454 Carbon Steel Pipes Marking
Each pipe having passed the inspection shall be marked with the following items. However, the smaller pipes or other pipes specified by the purchaser may be bundled together and marked for each bundle by a suitable means. In both cases, the order of arranging the marked items is not specified.
