Frequently Asked Questions (FAQ)
-
Q: What is the main advantage of helical perforation over straight perforation?
A: Helical perforation provides a more uniform distribution of open area along the tube length, improving sound absorption across a wider frequency range and reducing resonance peaks. -
Q: Can you customize the hole size and pattern?
A: Yes, we can customize hole diameter, pitch, and open area ratio according to your specific acoustic requirements. Please provide your design parameters. -
Q: What is the maximum temperature this tube can withstand?
A: 304 stainless steel can handle intermittent temperatures up to 870°C and continuous service up to 650°C, making it suitable for exhaust systems. -
Q: Do you offer samples before bulk order?
A: Yes, we provide samples for quality evaluation. Sample cost is negotiable, and we can refund upon bulk order placement. -
Q: What is the typical lead time for a 1000-piece order?
A: Lead time is approximately 15-25 working days, depending on complexity and current production schedule. Expedited options are available upon request. -
Q: How do you ensure the quality of perforated tubes?
A: We have a strict quality control system including raw material inspection, in-process checks, and final dimensional/visual inspection. Each batch is tested for open area ratio and mechanical properties. -
Q: Is the tube suitable for outdoor use?
A: Yes, 304 stainless steel offers excellent atmospheric corrosion resistance, making it ideal for outdoor acoustic silencers in industrial or urban settings. -
Q: What payment terms do you accept?
A: We accept T/T, L/C, and other common terms. Minimum order quantity is negotiable for first-time customers.
