FAQ Section
Q: What distinguishes welded from seamless pipes?
A: Welded pipes are formed from rolled steel sheets with a longitudinal weld, suitable for medium-pressure applications. Seamless variants are extruded from solid billets, offering superior pressure containment.
Q: Can I request non-standard diameters?
A: Yes, we accommodate diameter modifications from 10mm to 120mm through our custom manufacturing service.
Q: What certifications accompany shipments?
A: All shipments include material test certificates with chemical composition and mechanical properties. ISO9004/14000 documentation is provided upon request.
Q: How does 316 stainless outperform 304?
A: 316 contains molybdenum (2-3%) for enhanced chloride resistance, making it ideal for marine and chemical environments.
Q: What packaging options are available?
A: Standard packaging includes plastic caps and bundled wrapping. Wooden crates available for international shipments.
Q: Do you provide material samples?
A: Sample cuttings (≤300mm) are available for material verification prior to bulk orders.
Q: What's the minimum order quantity?
A: MOQ starts at 500kg, with volume discounts applied for orders exceeding 5 tons.
