What are the common specifications and wall thicknesses of seamless steel pipes?
ere are some common specifications for seamless steel pipes (outer diameter × wall thickness, mm):
Hot-rolled pipe: Outer diameter: >38～630; Wall thickness: 3～80; Common specifications: 42×4, 50×5, 89×6, 108×4.5, 133×7, 159×6, 219×6, 273×8, 325×8.5
Cold-drawn (cold-rolled) pipe: Outer diameter: 6～720; Wall thickness: 0.25～120; Common specifications: 22×2.5, 25×2.5, 32×3, 38×4, 45×3
Common standards and materials:
Standards: GB/T 8162 (for structural use), GB/T 8163 (for fluid transport);
Materials: 10#, 20#, 35#, 45#, 16Mn, etc.
When purchasing, the following must be specified: the applicable standard, the intended use, the outer diameter, the wall thickness, and the tolerances.
After I place an order and it enters the production process, can I get real-time updates on the production progress, quality inspection status, and other information about the steel?
If we purchase steel bars in bulk through your platform, do you accept third-party re-inspection? At what frequency should mechanical properties and chemical composition be sampled?
The platform fully accepts and supports third-party re-inspection of steel bars purchased in bulk. This is a routine and important step in ensuring the quality and fairness of bulk steel transactions.
The sampling frequency for third-party re-inspection follows the industry standard of "batch inspection, with 60 tons as the base and additional samples for quantities exceeding 40 tons". Chemical composition is mainly determined according to the furnace/tank number, while mechanical properties are sampled incrementally as the batch size increases. The platform accepts third-party re-inspections. The specific sampling and testing procedures can be further confirmed with the platform or your designated third-party testing agency during the order execution stage.
