Frequently Asked Questions (FAQ)
-
Q: What information is included in the Material Test Certificate?
A: The MTC includes chemical composition (C, Mn, Si, P, S, Cr, Ni, Mo, etc.), mechanical properties (yield strength, tensile strength, elongation), and hardness test results, all traceable to the heat number. -
Q: What is Eddy Current Testing and why is it important?
A: Eddy current testing is a non-destructive method that detects surface and near-surface defects such as cracks, laps, and pinholes. 100% testing ensures that every pipe is free from critical flaws, enhancing safety and longevity. -
Q: Can you customize pipe dimensions beyond standard sizes?
A: Yes, we offer custom diameters, wall thicknesses, and lengths. Please provide your requirements for a tailored solution. -
Q: What is the minimum order quantity (MOQ)?
A: Our standard MOQ is 1 ton for common sizes, but smaller quantities may be available for samples or urgent projects. Contact us to discuss. -
Q: How long does delivery typically take?
A: For standard sizes, delivery is 15-25 days after order confirmation. Custom orders may require 30-45 days, depending on complexity. -
Q: Is the pipe suitable for high-temperature applications?
A: 316 stainless steel offers good oxidation resistance up to 870°C (1600°F) in continuous service, and 925°C (1700°F) in intermittent service. However, for specific high-temperature designs, please consult our engineers. -
Q: What packaging do you use for export?
A: Pipes are bundled with steel straps, protected by plastic caps, and wrapped in waterproof paper or wooden crates for sea freight. Custom packaging is available. -
Q: Do you offer samples before bulk order?
A: Yes, we can provide small samples (e.g., 30cm length) for testing. The sample cost is negotiable, and shipping is at your expense.
