Dimensions Tolerance of JIS G3454 Carbon Steel Pipes

Division	Tolerances on outside diameter	Tolerances on wall thickness
Hot-finished seamless steel pipe	40 A or under 0.5mm	Under 4mm +0.6mm -0.5mm 4mm or over +15% -12.5%
	50A or over up to and incl. 125 A 1%
	150A 1.6mm
	200A or over 0.8% For the pipe of nominal size 350 A or over, the tolerances on outside diameter may be determined by the measurement of the length of circumference. In this case, the tolerances shall be 0.5%.
Cold-finished seamless steel pipe and electric resistance welded steel pipe	25 A or under 0.3mm	Under 3mm 0.3mm 3mm or over 10%
	32 A or over 0.8% For the pipe of nominal size 350 A or over, the tolerances on outside diameter may be determined by the measurement of the length of circumference. In this case, the tolerances shall be 0.5%.
