| Property | Parameter | Description |
|---|---|---|
| Product Name | Seamless Steel Pipe for Structural Construction | Hot-rolled or cold-drawn seamless carbon steel pipe used in structural and load-bearing applications |
| Material Grade | ASTM A106 Gr.B / A53 Gr.B; EN 10210 S355J2H; GB/T 8162 20# / 45#; JIS G3444 STK400 | International equivalent grades available; grade selection based on structural load and service condition |
| Standard Compliance | ASTM A106 / A53; EN 10210-1; GB/T 8162; JIS G3444 | Complies with major international structural pipe standards for mechanical and dimensional requirements |
| Chemical Composition (C) | ≤ 0.30% (A106 Gr.B); ≤ 0.22% (S355J2H) | Carbon content controlled to ensure weldability and structural integrity |
| Chemical Composition (Mn) | 0.29% – 1.06% (A106 Gr.B); ≤ 1.60% (S355J2H) | Manganese enhances tensile strength and toughness of the pipe |
| Chemical Composition (P / S) | P ≤ 0.035%; S ≤ 0.035% | Low phosphorus and sulfur content minimizes brittleness and improves weld quality |
| Chemical Composition (Si) | ≥ 0.10% (A106 Gr.B); ≤ 0.55% (S355J2H) | Silicon acts as a deoxidizer and contributes to strength |
| Tensile Strength | ≥ 415 MPa (A106 Gr.B); ≥ 470 MPa (S355J2H) | Minimum tensile strength per respective standard; ensures structural load capacity |
| Yield Strength | ≥ 240 MPa (A106 Gr.B); ≥ 355 MPa (S355J2H) | Minimum yield strength ensuring resistance to permanent deformation under structural loads |
| Elongation | ≥ 30% (A106 Gr.B); ≥ 22% (S355J2H) | Minimum elongation in 2-inch gauge length; indicates ductility and energy absorption capacity |
| Outer Diameter (OD) Range | 21.3 mm – 660 mm | Wide OD range to accommodate various structural column, beam, and truss applications |
| Wall Thickness Range | 2.0 mm – 60 mm | Wall thickness selected based on design pressure and structural load requirements |
| Length | Standard: 6 m / 12 m; Custom: up to 18 m | Fixed or random lengths available; custom cutting service offered per project specification |
| Surface Finish | Black varnished, bare, hot-dip galvanized, or epoxy coated | Surface treatment selected based on corrosion protection requirement and service environment |
| Application | Structural columns, trusses, scaffolding, bridges, machinery frames, building foundations | Widely used in civil engineering, industrial construction, and infrastructure projects |
| Certification | ISO 9001; CE Marking (EN 10210); Mill Test Certificate (MTC) per EN 10204 3.1 | Third-party inspection available; full traceability documentation provided with each shipment |
| Packaging | Bundled in hexagonal bundles (1–3 MT per bundle); steel strip strapping; end caps fitted | Seaworthy export packaging available; wooden dunnage and waterproof wrapping upon request |
| MOQ | 5 MT per grade/size | Mixed container orders accepted; spot stock available for standard sizes with short lead time |
Initial documentation issue resolved promptly — quality of pipe itself is good
We ordered 20 metric tons of ASTM A500 Grade B seamless pipe, OD 219.1 mm, wall thickness 12.7 mm, for a commercial building column application in Dubai. The pipe dimensions and mechanical properties — yield 318 MPa, tensile 408 MPa — were fully compliant. However, the initial shipment documentation was missing the BV third-party inspection certificate, which caused a hold at Dubai customs for four days. After escalating to the sales manager, the certificate was emailed within two hours and the physical copy arrived by courier the following day. The issue was resolved and the pipe passed inspection without any quality findings. Would recommend, but advise confirming all documentation checklist before vessel departure.
