The material used for this welded steel pipe is carbon steel, which is known for its strength, durability, and versatility in various applications. Carbon steel is widely used in the manufacturing of pipes due to its excellent mechanical properties and cost-effectiveness.
The welded steel pipe conforms to the Japanese Industrial Standard (JIS) G3452. This standard specifies the requirements for carbon steel pipes used for pressure service at an ambient temperature. The JIS G3452 standard ensures the quality and performance of the pipe, making it suitable for oil pipeline construction.
The chemical composition of the hot-rolled carbon steel used in the welded pipe is crucial in determining its mechanical properties and overall performance. The following table presents the typical chemical composition of the carbon steel used in the JIS G3452 standard:
| Element | Carbon (C) | Silicon (Si) | Manganese (Mn) | Phosphorus (P) | Sulfur (S) |
|---|---|---|---|---|---|
| Composition (%) | 0.22-0.30 | 0.30 max | 0.30-0.90 | 0.040 max | 0.040 max |
The mechanical properties of the welded steel pipe are essential in determining its strength and ability to withstand various stresses during oil pipeline construction. The following table showcases the typical mechanical properties of the hot-rolled carbon steel pipe as per the JIS G3452 standard:
| Property | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) | Hardness (HRB) |
|---|---|---|---|---|
| Minimum Value | 345 | 175 | 30 | 65 max |
The JIS G3452 standard designates the steel grade of the welded carbon steel pipe as STPG (e.g., STPG370 or STPG410). The steel grade represents the strength and composition of the carbon steel used in the pipe, ensuring its suitability for oil pipeline construction.
The welded steel pipe, manufactured with hot-rolled carbon steel according to the JIS G3452 standard, finds its primary application in oil pipeline construction. The pipe's high tensile strength, excellent weldability, and corrosion resistance make it ideal for transporting oil and other petroleum products over long distances.
