As a professional manufacturer with over 25 years of experience, Anping County Boli Hardware Wiremesh Products Factory proudly presents our Stainless Steel Perforated Tubes for Exhaust Muffler and Silencer Systems. These tubes are engineered to effectively reduce noise while maintaining optimal exhaust flow, making them a core component for high-performance mufflers and silencers. Our factory, established in 1998, combines advanced perforation technology with strict quality control to deliver reliable, durable products that meet the diverse needs of global customers.
Our perforated tubes are manufactured from premium stainless steel grades (304, 316, etc.), offering excellent corrosion resistance, high-temperature stability, and long service life. The precise perforation patterns ensure consistent acoustic performance, helping to attenuate sound waves without creating excessive back pressure. Whether you need standard sizes or fully customized designs, we provide flexible solutions to match your specific muffler and silencer requirements.
- Material Options: 304, 304L, 316, 316L stainless steel – resistant to oxidation, exhaust gases, and thermal cycling.
- Perforation Patterns: Round holes, square holes, slots, or custom shapes – optimized for sound absorption and flow efficiency.
- Open Area Ratio: 10% to 60% – adjustable to balance noise reduction and back pressure.
- Dimensions: Outer diameter from 20mm to 200mm, wall thickness 0.5mm to 3.0mm, length up to 6000mm (customizable).
- End Connections: Plain ends, flanged, threaded, or welded – ready for integration into your system.
- Surface Finish: Annealed, pickled, or as-welded – optional passivation for enhanced corrosion resistance.
| Parameter | Available Range |
|---|---|
| Outer Diameter (OD) | 20 mm – 200 mm |
| Wall Thickness | 0.5 mm – 3.0 mm |
| Perforation Hole Diameter (Round) | 1.0 mm – 12.0 mm |
| Open Area | 10% – 60% |
| Length | Up to 6000 mm (custom) |
| Tolerance | ±0.1 mm (on request) |
Our tubes are manufactured using advanced CNC punching machines and automated welding processes, ensuring uniform perforation and consistent quality across every batch. The stainless steel material not only withstands high exhaust temperatures (up to 800°C for 316 grade) but also resists road salt, moisture, and chemical corrosion, making them ideal for automotive, marine, and industrial exhaust systems.
Benefits for Your Muffler & Silencer Systems:
- Effective noise reduction through acoustic tuning of perforation pattern and open area.
- Minimal back pressure loss, preserving engine performance and fuel efficiency.
- Extended service life compared to carbon steel or aluminized tubes.
- Lightweight yet strong construction – reduces overall system weight.
- Customizable to fit any muffler geometry – round, oval, or rectangular housings.

Frequently Asked Questions (FAQ)
Q1: What stainless steel grades are available for perforated tubes?
We offer 304, 304L, 316, and 316L stainless steel. Grade 304 is cost-effective for general exhaust systems, while 316/316L provides superior corrosion resistance for marine or high-humidity environments.
Q2: How does the open area ratio affect noise reduction?
A higher open area reduces back pressure but may allow more sound to pass. Lower open area increases noise attenuation but can restrict flow. Our engineers can help you select the optimal ratio based on your target noise level and engine displacement.
Q3: Can you produce tubes with non-circular perforations?
Yes, we can produce square, slot, hexagonal, or custom-shaped perforations according to your design. Please provide a drawing or description of the required pattern.
Q4: What is the typical lead time for custom orders?
For standard sizes and materials, lead time is 15–20 working days. For fully customized tubes (special perforation, length, or end connections), lead time is 20–30 working days, depending on quantity.
Q5: Do you provide samples before mass production?
Yes, we can produce sample tubes for evaluation. Sample fees are charged initially but can be refunded upon bulk order placement. Please contact us for details.
Q6: What is the maximum working temperature for these tubes?
304 stainless steel can withstand up to 870°C in continuous service, while 316 grade handles up to 800°C. For extremely high-temperature applications, we recommend special alloys (available upon request).
Q7: How do you ensure the tubes are free from burrs and sharp edges?
We use deburring and passivation processes after perforation and welding. Each tube is manually inspected to ensure smooth edges, preventing injury and facilitating installation.
Q8: Can you supply tubes with flanged ends or welded brackets?
Absolutely. We can provide plain ends, flanged ends, threaded ends, or welded brackets/attachments per your drawing. Just share your requirements, and we will deliver ready-to-install components.
