1. Smart Engineering: Why Indoor Optimization Matters
As a professional ERW Steel Pipe Factory, we recognized that indoor environments don't require the extreme galvanization used in subsea projects, but they do demand more than raw steel. Our Indoor Use Steel Tubing is specifically designed to bridge this gap, offering a specialized Anti-Rust Varnish Coating that prevents oxidation caused by humidity while maintaining a practical price point.
2. Technical Superiority: The Strength of Carbon Steel
Every length of pipe produced by our Carbon Steel Pipe Manufacturer facility undergoes rigorous testing. We focus on the structural integrity of Structural ERW Pipe, ensuring that the high-frequency welding seam is as strong as the parent metal. This balance of strength and surface protection makes our pipes the ideal choice for HVAC and indoor scaffolding.
| Mechanical Property | Standard | Our Factory Result |
| Tensile Strength | ≥ 330 MPa | 420 - 460 MPa |
| Yield Strength | ≥ 205 MPa | 250 - 280 MPa |
| Elongation | ≥ 20% | 32% |
3. Surface Science: The Advantages of Black Varnish
Our Black Varnished Pipe Wholesale service provides customers with a "Ready-to-Install" finish. This Corrosion Protection for Steel is applied in a controlled factory environment, ensuring zero pinholes and uniform thickness. Unlike manual on-site painting, our industrial varnish bonds deeper into the steel pores, providing a long-term barrier against the "silent corrosion" found in indoor warehouses and factories.
4. Versatility and Specifications: Meeting Global Standards
From Thin-wall ERW Steel Pipe for lightweight framing to heavy-duty industrial fluid transport, we offer a vast range of dimensions. Our Industrial Interior Piping solutions follow international grading to ensure compatibility with standard fittings, reducing installation friction for contractors worldwide.
| Dimension Category | Outside Diameter | Varnish Thickness |
| Light Series | 21.3mm - 60.3mm | 20 -30 μm |
| Medium Series | 73.0mm - 114.3mm | 30 - 45 μm |
| Heavy Series | 141.3mm - 219.1mm | 45 -60 μm |
5. Economic Efficiency: Cost-Effective Piping Solutions
Our Cost-Effective Piping Solutions allow you to reallocate project funds where they are needed most. By sourcing directly from our factory, you eliminate the middleman and gain a product that is perfectly "Optimized for the Indoors"—durable enough to last decades, but practical enough to protect your bottom line.
