Frequently Asked Questions (FAQ)

Q: What is the standard hole size for this helical perforated tube?
A: Standard hole diameters range from 3 mm to 8 mm, with customizable pitch. The open area ratio can be adjusted between 30% and 60% to suit your application.
Q: Can you supply tubes with threaded ends or flanges?
A: Yes, we offer end finishing options including threading, flanging, and beveling. Please specify your requirements when placing an order.
Q: Is the 304 stainless steel suitable for outdoor use?
A: 304 SS offers good resistance to atmospheric corrosion, but for highly corrosive coastal or chemical environments, we recommend 316L stainless steel. Contact us for material selection advice.
Q: What is the minimum order quantity (MOQ)?
A: Our MOQ is typically 50 pieces for standard sizes. For custom specifications, please inquire and we can discuss based on your project volume.
Q: How long does it take to produce and ship?
A: Production lead time is usually 15-25 working days after order confirmation, depending on quantity and customization. Shipping time varies by destination; we can arrange sea, air, or express delivery.
Q: Do you provide free samples?
A: We can provide samples at cost, with the sample fee deducted from your first bulk order. Please contact our sales team for sample availability.
Q: Can the tube be used for high-temperature applications?
A: 304 stainless steel can withstand temperatures up to about 870°C (1600°F) in continuous service. For higher temperatures, consider 310S or Inconel alloys.
Q: What packaging do you use for export?
A: Tubes are bundled with protective caps, wrapped in plastic, and packed in wooden crates or pallets for safe transit. Custom packaging is available upon request.
