The production processes of JIS G3456 STPG370 STPG410 STPG480 carbon steel pipes for high temperature pipelines include seamless process, resistance welding process, spiral submerged arc welding process, and straight seam submerged arc welding process. They can be used as boiler tubes, superheater tubes, and heat exchange tubes. Since JIS G3456 STPG370 STPG410 STPG480 carbon steel pipes are used in high temperature environments, the standard has strict requirements for chemical element content and mechanical properties. All JIS G3456 STPG370 STPG410 STPG480 high temperature carbon steel pipes must pass the mechanical property and chemical element content tests before they can be delivered:
JIS G3456 STPG370 high temperature steel pipes require a maximum C content of 0.25%, a maximum Si content of 0.1-0.35%, a Mn content of 0.30-0.90%, a maximum P content of 0.035%, a maximum S content of 0.035%, a tensile strength of ≥370Mpa, and a yield strength of ≥215Mpa.
JIS G3456 STPG410 high temperature steel pipe requires a maximum C content of 0.30%, a maximum Si content of 0.1-0.35%, a Mn content of 0.30-1.0%, a maximum P content of 0.035%, a maximum S content of 0.035%, a tensile strength of ≥410Mpa, and a yield strength of ≥245Mpa.
JIS G3456 STPG480 high temperature steel pipe requires a maximum C content of 0.33%, a maximum Si content of 0.1-0.35%, a Mn content of 0.30-1.0%, a maximum P content of 0.035%, a maximum S content of 0.035%, a tensile strength of ≥480Mpa, and a yield strength of ≥275Mpa.
