Frequently Asked Questions
-
Q: What is the difference between a helically perforated tube and a wedge wire screen?
A: A helically perforated tube is made by cutting a continuous spiral slot into a solid tube wall, while a wedge wire screen is formed by wrapping V-shaped wire around a support structure. Our helical design offers a smooth internal surface and uniform flow distribution, suitable for higher pressure ratings. -
Q: Can you provide tubes with a different outer diameter?
A: Yes, we can manufacture tubes with outer diameters ranging from 20mm to 200mm. Please contact us with your specific requirements. -
Q: What is the maximum operating temperature for 304 stainless steel helically perforated tubes?
A: 304 stainless steel can be used at temperatures up to 870°C in intermittent service and 925°C in continuous service. However, for oil and gas filtration, typical operating temperatures are below 400°C. -
Q: Do you offer tubes with threaded ends?
A: Yes, we can provide plain ends, NPT or BSP threaded ends, or flanged ends. Please specify your connection type when ordering. -
Q: How do you ensure the slot width accuracy?
A: Our manufacturing process uses CNC-controlled laser or plasma cutting, followed by quality inspection with precision gauges. Slot width tolerance is within ±0.1mm. -
Q: What is the minimum order quantity?
A: For standard sizes, the MOQ is 50 pieces. For custom specifications, please inquire. We are flexible for sample orders. -
Q: Can you provide a certificate of material?
A: Yes, we can issue a mill test certificate for the 304 stainless steel material upon request. -
Q: How long is the delivery time?
A: Typically 15–25 working days after order confirmation, depending on quantity and customization. We can expedite for urgent orders.
