Oiled Carbon Steel Round Tube
Choosing the Right Oiled Carbon Steel Round Tube for Your Project
For applications demanding both durability and reliable corrosion protection during transit and storage, oiled carbon steel round tube stands as a premier choice. This product involves applying a thin, uniform coating of rust-preventative oil to the surface of a high-quality carbon steel tube, creating a temporary barrier against moisture and oxidation. This protective layer is particularly crucial for projects where long-term storage or exposure to humid environments is anticipated before final installation and coating. Whether you require the robust integrity of a Seamless Carbon Steel Round Tube for high-pressure systems or the cost-effective solution of an ERW Carbon Steel Round Pipe for structural frameworks, the oiled finish ensures the material arrives on-site in pristine, work-ready condition. Our inventory includes tubing manufactured to stringent international standards, such as ASTM A53 Carbon Steel Round Tube for general service and ASTM A106 Grade B Round Pipe for high-temperature applications, all available with this protective oil coating.
Detailed Specifications of Our Oiled Carbon Steel Round Tube
Understanding the precise specifications of Oiled Carbon Steel Round Tube is essential for ensuring it meets your project's structural and environmental requirements. Our product range is defined by meticulous attention to material composition, dimensional accuracy, and performance characteristics. The oil coating itself is a high-quality, non-polymerizing oil designed to be easily removed with standard industrial solvents prior to welding, painting, or galvanizing, leaving a clean surface for further processing.
Key Material Properties:
- Base Material: High-strength low-alloy carbon steel.
- Standard Grades: Common grades include ASTM A53 Grade B, ASTM A106 Grade B, API 5L Grade B, and equivalent international standards.
- Yield Strength: Ranges from 35,000 psi (240 MPa) to 60,000 psi (415 MPa) depending on the specific grade.
- Tensile Strength: Typically between 60,000 psi (415 MPa) and 75,000 psi (515 MPa).
- Surface Finish: Hot-rolled, pickled, and oiled (HRPO) or cold-drawn and oiled, providing a smooth surface ideal for the protective coating.
- Oiling Process: Applied via a controlled dip or spray process to ensure a complete, uniform film across the entire surface, including the inner diameter.
Standard Available Sizes & Tolerances:
| Outer Diameter (OD) | Wall Thickness (WT) Schedule | Length | Standard Tolerance (OD & WT) |
|---|---|---|---|
| 1/2" (21.3 mm) to 24" (609.6 mm) | Sch 10, 40, 80, STD, XS, XXS | Random (18'-22'), Single Random (18'-25'), or Cut to Length | +/- 1% or +/- 0.005", per ASTM A530 |
| 25 mm to 630 mm | As per EN, DIN, JIS, and other international specifications | 5.8m, 6m, 11.8m, 12m, or Custom | As per applicable DIN 2448/ EN 10219/ JIS G3444 standards |
Applications & Benefits:
- Primary Applications: Ideal for structural components, mechanical tubing, fabrication parts, and as raw material for machined components where interim corrosion protection is needed.
- Storage & Handling: The oil film significantly extends safe storage life in non-climate-controlled warehouses, reducing material waste and loss.
- Fabrication Ready: Despite the coating, the tube remains readily weldable and formable after proper cleaning, with no compromise to the base metal's properties.
- Packaging: Typically bundled and wrapped with waterproof material for additional protection during international shipping.
