JIS G3463 Stainless Steel Tubes For Boiler

Product Description

JIS G 3463 standard applies to seamless stainless steel tubes used in equipment such as heat exchangers and condensers, focusing on the corrosion resistance, high temperature resistance and mechanical properties of the material. It is mainly used in heat exchange equipment in industries such as petrochemicals, power, ships, food processing, and pharmaceuticals.

JIS G3463 stainless steel boiler tubes are made of SUS 304TB, SUS304HTB, SUS304LTB, SUS309TB, SUS309STB, SUS310TB, SUS310STB, SUS312LTB, SUS316TB, SUS316HTB, SUS316LTB.

company advantage

GNEE factory production strictly complies with JIS G3463 standards (such as SUS304 TB, SUS316 TB and other brands), and is compatible with international standards such as ASTM, EN, GB, etc., ensuring that the products meet industrial-grade requirements in terms of chemical composition, mechanical properties (such as tensile strength ≥515MPa, elongation ≥35%) and dimensional tolerance (outer diameter 15.88-114.3mm, wall thickness 1.2-8.0mm).
Equipped with ultrasonic flaw detection, eddy current flaw detection, direct reading spectrometer, mechanical properties testing machine and other equipment, the pipes are tested throughout the process (such as intergranular corrosion test, high temperature creep test), and ISO 9001 certification is passed. Some companies meet international standards such as FDA and PED to ensure product safety and reliability.
