JIS Seamless Pipes

JIS seamless pipes are steel pipe that have been created by JIS and meets certain performance requirements.

Japanese Industrial Standards (JIS) developed by the organization apply to a wide variety of industrial services and technologies such as automobiles, metallurgy, ships and medical equipment

The method for making cold-drawn seamless pipes involves taking a round “billet” or bar of steel and boring it in the center, turning it, cutting it, heating it to make it more pliable, then “drawing” it (extruding or pulling it) to make it a longer and thinner tube.

Japanese Industrial Standards for steel

Japanese Industrial Standards specifies the standards used for industrial activities in Japan. The standardization process is coordinated by Japanese Industrial Standards Committee and published through Japanese Standards Association. The Industrial Standardization Law was revised in 2004 and the JIS mark product certification system was changed. Standards are named like “JIS X 0208:1997″, where X denotes area division, followed by four digits (or five digits for some of the standards corresponding ISO standards) and the revision release year.

  • G – Ferrous Materials and Metallurgy
  • H – Nonferrous Materials and Metallurgy

MTC IN EN 10204.3

EN 10204:2004 is for metallic products-and this norm tell us things about Types of inspection documents. There are no material standards.

Mostly material is defined with its chemical composition and mechanical properties in a public standars like ISO, EN, JIS, ASTM etc.

What is JIS?

Japanese Industrial Standards (JIS) specifies the standards used for industrial activities in Japan. The standardization process is coordinated by Japanese Industrial Standards Committee and published through Japanese Standards Association.


Tolerance of JIS seamless pipe

The tolerance of a kind of JIS 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.
