Frequently Asked Questions
Q: What grades of stainless steel do you offer? A: We provide a wide range including 200 series (201, 202), 300 series (304, 304L, 316, 316L, 321), 400 series, and Duplex Steel (2205, 2507).
Q: What is the difference between your seamless and welded pipes? A: We provide both techniques depending on your application needs. Seamless pipes are ideal for high-pressure environments, while welded tubes are cost-effective for decorative and sanitary applications.
Q: What surface treatments can I choose from? A: Available surfaces include No.1, 2B, BA, 6K, 8K Mirror, No.4, and Hairline (HL) finishes.
Q: How do you handle the settlement of the goods? A: All our stainless steel tubes are traded based on actual net weight rather than theoretical weight to ensure fairness.
Q: What testing procedures do products undergo? A: Products undergo a rigorous suite of tests including eddy current, hydrostatic, pneumatic, tensile strength, and metallographic corrosion tests.
Q: Can you provide customized processing services? A: Yes, we offer welding, painting, bending, flaring, cutting, punching, and polishing services to meet specific project requirements.
