Tolerance for different outside diameter among JIS seamless steel pipe

The tolerance of a kind of seamless steel pipe would be decided by many factors. And today, our main topic would focus on the outside diameter. Same standard for the JIS tube would have different tolerance resistance. And for different standard, the difference is also various. The compared steel pipe's types would be focus on JIS G3441, G3444 and G3445. And the outside diameter would be focus on specific data, such as 50, 25, 80-90 and so on. With more details, we can get from the list below.
