Frequently Asked Questions (FAQ)
Q1: What type of stainless steel is used? Is it magnetic?
A: Our perforated tubes are made from 304 stainless steel, which is non-magnetic in the annealed state. However, after working (bending, welding), slight magnetism may appear, but it does not affect performance.
Q2: Can I get a custom diameter or length?
A: Yes, we offer custom sizes. Please provide your required outer diameter, wall thickness, and length. We can also adjust the perforation pattern and hole size according to your specifications. Minimum order quantity for custom sizes may apply.
Q3: How does the perforation affect exhaust sound?
A: The perforated tube acts as a resonator core. The holes allow exhaust gases to escape into the surrounding muffler packing material, which absorbs sound waves and reduces noise. The open area percentage and hole pattern influence the tone – larger holes produce a deeper sound, while smaller holes give a more subtle attenuation.
Q4: Is this tube suitable for a diesel vehicle?
A: Yes, 304 stainless steel can withstand the higher temperatures and corrosive exhaust gases of diesel engines. However, for heavy-duty applications, we recommend a thicker wall (2.0mm or more) for added durability.
Q5: What is the lead time for standard and custom orders?
A: Standard sizes are typically in stock and can be shipped within 7-15 days after payment. Custom orders require 20-30 days for production, plus shipping time. We recommend contacting us for current lead times.
Q6: Can I get a sample before placing a bulk order?
A: Absolutely. We offer free samples for standard sizes (you pay shipping). For custom samples, a small sample fee may apply, which will be deducted from your first bulk order. Contact us to arrange.
Q7: What is the packaging like for export?
A: Each tube is individually wrapped in plastic film, then packed with foam inserts inside a sturdy carton. For bulk orders, we use wooden crates or pallets to prevent damage during transit. We can also customize packaging with your brand logo if required.
Q8: Do you provide any warranty?
A: We offer a 12-month warranty against manufacturing defects, such as material flaws or inconsistent perforation. Normal wear and tear, improper installation, or modifications are not covered. Please inspect upon receipt and report any issues within 7 days.
