FAQ
Q: Can ASTM A106 Grade B be used as API 5L Grade B?
A: They are often dual-certified. However, API 5L has stricter requirements for toughness and chemical composition for pipeline use, whereas A106 is optimized for high-temperature pressure service.
Q: What is the difference between seamless and welded pipes?
A: Seamless pipes offer superior pressure resistance and uniform wall thickness, making them ideal for high-pressure applications. Welded pipes provide cost-effective solutions for lower-pressure systems.
Q: Do you provide mill test certificates?
A: Yes, we provide comprehensive mill test certificates with each shipment, including chemical composition, mechanical properties, and dimensional data.
Q: What is your typical delivery time?
A: Standard products ship within 15-20 days. Custom orders may require 25-35 days depending on specifications and quantity.
