The JIS G3465 Large-Diameter Seamless Steel Pipe is a high-quality drilling pipe manufactured in accordance with the Japanese Industrial Standard JIS G 3465:2019, specifically designed for applications such as oil and gas exploration, geothermal wells, test drilling, and mineral boreholes. This is a seamless steel pipe, meaning it is manufactured without welded seams, ensuring superior mechanical strength, pressure resistance, and reliable performance in demanding drilling environments.
| Parameter | Typical Range/Value |
|---|---|
| Standard | JIS G 3465:2019 – Seamless Steel Pipe for Drilling |
| Outside Diameter (OD) | 30 mm – 180 mm (varies by application) |
| Wall Thickness | 3 mm – 20 mm (typical drilling pipe wall thickness) |
| Length | Custom (typically 6–12 meters) |
| Manufacturing Process | Seamless (hot-rolled or cold-drawn) |
| Surface Finish | Oiled or as requested |
High Strength and Durability: Engineered to withstand the mechanical stresses encountered during drilling operations.
Excellent Pressure and Temperature Resistance: Suitable for deep drilling, where pipes face extreme downhole conditions.
Corrosion and Abrasion Resistance: Resists corrosion and wear from drilling fluids and abrasive formations.
Seamless Construction: Eliminates weak longitudinal welds, enhancing pipe integrity and fatigue life.
We understand the key concerns in the drilling industry — reliability, durability, and material traceability. Here's how this product addresses them:
Consistent Quality and Traceability
Our seamless steel pipes are manufactured to the strict JIS G3465 standards, ensuring consistent chemical composition, mechanical properties, and dimensional tolerances for reliable performance in the field.
High Load and Cycle Resistance
Optimized materials and heat treatment processes provide high tensile and fatigue resistance, reducing failures and downtime.
Wide Application Compatibility
The pipes are suitable for casing tubes, drill rods, and core tubes, meeting drilling system requirements for oil, gas, and mineral exploration projects.
Custom Size and Surface Finish Options
We support custom diameters, wall thicknesses, and surface treatments, ensuring seamless integration with customers' drilling tool systems and couplings.
Below are typical compositions for grades under JIS G3465, with element percentages (by weight):
