Audited Supplier Audited by an independent third-party inspection agency
Standard Compliance: GB/T 3091 (China) / Equivalent to ASTM A53 (Grade B) or JIS G3444.
Material Grade: Q235B (Carbon structural steel with ≤0.20% C, 0.30% Si, 0.35-1.40% Mn).
Key Feature: Cost-effective, general-purpose steel pipe with good weldability and formability for low-to-medium stress applications.
| Property | Technical Specifications |
|---|---|
| Mechanical Strength | Tensile strength: 370-500 MPa Yield strength: ≥235 MPa Elongation: ≥26% (ductile for bending/forming). |
| Temperature Range | Suitable for service from -20°C to 300°C (avoid prolonged high-temp use). |
| Corrosion Resistance | Moderate resistance; coatings (galvanizing, painting) required for humid/corrosive environments. |
| Workability | Excellent for welding, cutting, and machining without preheating. |
Construction: Structural frameworks, scaffolding, and support columns.
Utilities: Water, gas, and HVAC distribution systems.
Agriculture: Irrigation pipes, greenhouse frames, and machinery components.
Industrial: Conveyor systems, storage racks, and low-pressure fluid transport.
Welding Method: High-frequency induction welding (HFIW) or submerged arc welding (SAW) for uniform seams.
Surface Treatment: Hot-dip galvanizing (GB/T 13912) or epoxy coating for corrosion protection.
Testing: Hydrostatic testing, visual inspection, and dimensional tolerance checks per GB/T 3091.
Affordability: Lowest cost among structural steel pipes, ideal for budget-sensitive projects.
Versatility: Adaptable to coatings and fabrication methods (threading, flanging).
Compliance: Meets ISO 630, EN 10219, and CE standards for global acceptance.
Availability: Sizes from ½" to 24" OD, wall thickness 1.0-12.7 mm.
Target Industries: Construction, infrastructure, agriculture, and light manufacturing.
Key Selling Points:
Ideal for non-critical structural applications with short-term ROI.
Widely used in emerging markets for residential and small-scale industrial projects.
Certifications: Ensure supplier provides MTC (Mill Test Certificates) with chemical/mechanical data.
Coating Options: Specify galvanizing (e.g., 60-100g/m² zinc coating) for outdoor use.
Packaging: Bundled with protective caps or PVC sleeves to prevent edge damage during transit.
