Dual Grade 304/316L Stainless Steel Seamless Pipe ASTM A312 SCH10-80 Seamless Tube Factory Supply
1.Product Description
This product is export-grade stainless steel seamless pipe, manufactured strictly to internationally recognized standards (ASTM/ASME/EN/GB) and adapted for multimodal transport including sea, air, and land freight. Prior to shipment, each batch undergoes anti-corrosion treatment, end protection, stencil marking, and waterproof moisture-proof packaging to ensure no rusting, impact deformation, or label detachment during long-distance ocean transit under high-temperature, high-humidity, and salt-spray conditions. A complete bilingual documentation package (commercial invoice, packing list, Certificate of Origin, Mill Test Certificate, Bill of Lading, and customs declaration elements) accompanies each shipment, facilitating rapid customs clearance at major global ports (e.g., Houston, Rotterdam, Singapore, Shanghai).
2. Product Applications
This export logistics guide applies to the following international trade scenarios:
| Application Scenario | Specific Requirements |
| FOB/CIF ocean export | Suitable for 20ft/40ft standard containers or break-bulk vessel holds; meets stacking and lashing requirements |
| Direct supply for international EPC projects | Packed by construction sequence and zone; ready for direct installation upon arrival without secondary sorting |
| Cross-border rail (China-Europe Railway Express) | Meets railway loading gauge limits; single bundle length ≤12.5m; packaging resists vibration and compression |
| Bonded warehousing at destination | External labels include full material details (grade, size, PO#) for WMS barcode scanning |
| Transshipment trade (intermediate port de-vanning) | Inner packaging individually sealed, outer cases reinforced for multiple hoisting and short-distance transfers |
3. Product Advantages
Excellent marine weather resistance: Exterior coated with weldable rust-preventive primer, combined with VCI rust-preventive paper inner lining and double-layer stretch film, provides ≥90 days of rust protection in salt-spray environments (ISO 9227), eliminating the need for additional pickling upon arrival.
Reliable end damage protection: Standard plastic end caps (or optional metal thread protectors) effectively absorb axial impacts during hoisting and transit, maintaining bevel edge integrity ≥99.5%.
Permanent legible marking: High-adhesion seawater-resistant ink is used for stenciling on both ends (within 1m) — displaying grade, heat number, size, PO#, and destination code — remaining readable even after saltwater spray and UV exposure.
Optimized container stuffing: Professional palletization and container stowage plans (weight distribution) maximize per-container loading (13~16 tons per 20ft container) while ensuring balanced weight distribution to avoid listing and maritime incidents.
Zero-error customs compliance: Pre-vetted by a professional customs team covering HS codes (7304 series), rules of origin, and destination-country import license requirements, ensuring one-time clearance with near-zero demurrage risk.
Full track-and-trace visibility: Tamper-proof QR code labels affixed to each bundle allow instant scanning for electronic MTCs, packing photos, and real-time logistics tracking — achieving "end-to-end visibility" from mill to site.
