JIS G 3465:2019 is a Japanese Industrial Standard that establishes the specifications for seamless steel tubes used in drilling applications. These tubes are specifically designed for use as casing tubes, core tubes, and drill rods in various drilling operations such as test-drilling, drilling of hot springs, wells, mines, and other related activities.

The standard provides essential requirements and guidelines for the manufacturing and quality control of these tubes. It covers a range of outer diameter sizes, including 43 mm to 142 mm for casing tubes, 34 mm to 180 mm for core tubes, and 33.5 mm to 50 mm for drill rods. These size ranges ensure that the tubes are suitable for different drilling scenarios and can accommodate the specific needs of the drilling industry.
