FAQ
What's the difference between seamless and welded SS pipes?
Seamless Pipes: No welding joints, higher pressure resistance, and uniform structure. Best for high-stress applications (oil/gas, aerospace).
Welded Pipes: Cost-effective, available in larger sizes, suitable for low/medium-pressure uses (water supply, construction).
How do I choose the right grade (e.g., 304 vs. 316)?
- 304 (18/8 Stainless Steel): General-purpose, resists rust & acids (kitchen equipment, piping).
- 316 (Marine Grade): Contains Mo (Molybdenum) for saltwater/chemical resistance (shipbuilding, coastal structures).
- Duplex (2205): Higher strength, ideal for oil/gas and chemical processing.
Can I mix different grades/sizes to meet the 1-ton MOQ?
Absolutely! You can combine multiple grades, sizes, or specifications to reach 1 ton. Contact us for a customized quote.
What's the lead time for bulk orders?
Standard orders ship in 2–4 weeks. Expedited options are available—contact us for urgent needs.
