FAQ
Q1: What is the standard length of the tube?
A: The standard length is 6 meters, but we can customize lengths from 1m to 12m based on your requirements.
Q2: Can the hole pattern be customized?
A: Yes, we offer both staggered and straight hole patterns. The open area ratio can be adjusted by changing pitch. Please contact us for specific configurations.
Q3: Is this tube suitable for outdoor use?
A: 304 stainless steel provides good corrosion resistance for most outdoor environments. However, for highly corrosive coastal areas, we recommend 316L grade (available upon request).
Q4: What is the tolerance on wall thickness and hole diameter?
A: Wall thickness tolerance is ±0.1mm, hole diameter tolerance is ±0.2mm, ensuring consistent performance.
Q5: Do you provide samples for testing?
A: Yes, sample orders are welcome. We can provide a small quantity (e.g., 1 meter) for evaluation. Shipping cost is negotiable.
Q6: What is the packaging method for export?
A: Tubes are packed in bundles with protective wrapping (plastic film or steel strapping) and wooden crates if needed, to prevent damage during transit.
Q7: How long is the warranty period, and what does it cover?
A: The warranty is 2 years from the date of shipment, covering manufacturing defects such as weld failure, material cracks, or significant dimensional deviation. Normal wear and misuse are excluded.
Q8: Can you provide a certificate of material compliance?
A: Yes, we can issue a mill test certificate for 304 stainless steel upon request, confirming chemical composition and mechanical properties.
