JIS G3455 Standard Specification

What is JIS G3455 Standard?

JIS G3455 is a Japanese industrial standard that specifies carbon steel pipes for use in high-pressure environments. This standard covers pipes with a maximum outside diameter of 73.66mm and a maximum wall thickness of 9.53mm.
JIS G3455 standard is typically used in high-pressure applications, such as in power plants, where the pipes are subjected to high pressure and temperature. These pipes are also used in oil and gas pipelines, and other industrial applications where high pressure service is required.
One of the main features of JIS G3455 piping is its high strength and durability. The standard specifies the use of high quality materials and manufacturing processes to ensure that the pipes can withstand high pressure and high temperature conditions.
Another important aspect of JIS G3455 piping is its level of tight tolerance. The standard sets strict requirements for the size and shape of the pipe, which ensures high precision and consistency of the finished product. This is essential for the proper operation of the systems and equipment used for the pipes.
The JIS G3455 standard also includes testing and inspection of the pipes to ensure that they meet the required specifications. This includes tests such as tensile strength, elongation and hardness tests.
In summary, JIS G3455 is an important standard for the manufacture and use of high-pressure carbon steel pipe. Its stringent requirements for materials, manufacturing processes and testing ensure that the pipe is strong, durable and accurate, making it well suited for use in high-pressure applications.
When selecting pipe suitable for high-pressure applications, make sure that the pipe you choose meets JIS G3455 standards. This will give you peace of mind knowing that your pipe is made from quality materials, manufactured to exacting standards, and will perform as expected in the application.

JIS G3455 Carbon steel pipes for high pressure service.

1 Scope

This Standard specifies the carbon steel pipes (hereafter referred to as “pipes”) used for high pressure service at temperatures 350°C or lower. This Standard is generally applicable to pipes of outside diameters 10.5mm (nominal diameter 6A or 1/8B) to 660.4 mm (nominal diameter 650A or 26B).

In addition to the items specified in this text, the purchaser can previously designate special quality requirements upon agreement with the manufacturer, which are shown in Annex JA.
