JIS G3454/G3456 seamless steel pipe

Product parameters

Japanese standard seamless steel pipe is made of steel ingot or solid tube blank perforated into wool tube, and then made of hot rolled, cold rolled or cold drawn. Commonly used steel numbers are STPY41, STPG38, STB30, STB33, STB35, STPT42 and so on. Japanese standard seamless steel pipe is made of steel ingot or solid tube blank perforated into wool tube, and then made of hot rolled, cold rolled or cold drawn.

Hot rolled seamless steel pipe production process:

Tube blank → heating → perforation → three-high skew rolling and continuous rolling → Stripping → sizing → Cooling → straightening → hydraulic test → marking → lever effect seamless steel pipe in storage will be detected.

Cold-drawn seamless steel pipe production process:

Tube blank → heating → perforating → heading → annealing → pickling → oiling → multi-pass cold drawing → Tube blank → Heat treatment → straightening → hydraulic test → marking → storage. The wall thickness of cold-drawn seamless steel pipe is better than that of hot-rolled seamless steel pipe, and the surface roughness is also some.

Product information:

The existence of JIS G3456:2019 standard ensures the performance and reliability of these carbon steel pipes in high temperature environments, providing high-quality piping materials for a variety of high temperature applications. However, the specific material characteristics and conditions of use may vary due to different application requirements, so in practical applications, the specific content of the standard should be referred to and selected and used according to the actual situation.

JIS G 3456:2019 standard seamless steel pipe has excellent high temperature performance and pressure resistance, so it is widely used in pipeline systems in petroleum, chemical, electric power, boiler and other industries. It can be used to transport high temperature, high pressure fluid media, such as steam, oil and gas.

Features: JIS G 3456:2019 standard seamless steel pipe is manufactured by seamless process, the inner wall is smooth, not easy to scale, and the fluid resistance is small. At the same time, it also has good corrosion resistance and weldability, easy installation and maintenance.
