JIS G3454 Carbon Steel Pipes for Pressure Service
JIS G3454 carbon steel pipes used for pressure service at an approximate maximum temperature of 350℃
JIS G3454 Carbon Steel Pipes Dimensions and Tolerances
outside diameter: 20-800mm
wall thickness: 3-150mm
Dimensional Tolerances: +/-1% OD ; +/- 12% WT
JIS G3454 Carbon Steel Pipes Method of Manufacture
The Method of manufacture shall be as follows:
The pipe shall be manufactured by either the seamless of the electric resistance welding process.
The pipe shall stay as manufactured. However, the cold- finished steel pipe shall be annealed after manufacture.
The purchaser may specify heat treatment for the weld of the electric resistance welded steel pipe of grade STPG 42, as necessary.

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.
