As a specialized manufacturer established in 1998, Anping County Boli Hardware Wiremesh Products Factory brings over two decades of expertise to the production of the Durable Circular Air-blowing Chimney. This product is engineered for demanding industrial environments where reliability and continuous operation are critical. Each chimney is supplied with a Mill Test Report verifying material quality, and we back it with a 1-Year Warranty to give you peace of mind. Whether you need efficient exhaust or forced air circulation, our chimney is designed to perform.
The circular air-blowing chimney is crafted from high-grade carbon steel or stainless steel, chosen for strength and corrosion resistance. Its aerodynamic circular shape minimizes air resistance and maximizes airflow efficiency, making it ideal for continuous-duty applications in ventilation systems, dust collection, and exhaust stacks. The construction follows strict manufacturing standards, with every weld inspected and documented in the Mill Test Report.

Frequently Asked Questions (FAQ)
1. What is a Mill Test Report and why is it important?
A Mill Test Report (MTR) is a document that certifies the chemical composition and mechanical properties of the steel used in your chimney. It ensures traceability and compliance with industry standards, giving you confidence in material quality.
2. Can you customize the diameter and height of the chimney?
Yes, we offer full customization. You can specify any diameter from 500 mm to 2000 mm, and height according to your installation needs. Non-standard sizes are also available upon request.
3. What materials are available for the chimney?
We offer carbon steel grades (Q235, Q345) and stainless steel grades (304, 316L). The choice depends on your operating temperature, corrosive environment, and budget. Our team can help you select the best option.
4. Is the chimney suitable for outdoor use?
Absolutely. With proper surface treatment such as hot-dip galvanizing or weather-resistant paint, the chimney can withstand rain, UV, and temperature variations. We recommend stainless steel for highly corrosive coastal areas.
5. What does the 1-year warranty cover?
The warranty covers manufacturing defects in materials and workmanship. It does not cover damage caused by improper installation, misuse, or external factors. We provide clear guidelines to ensure warranty validity.
6. How long does it take to produce and deliver?
Production lead time is typically 15–25 working days after order confirmation, depending on quantity and complexity. Delivery to major ports takes additional transit time. We can expedite urgent orders upon request.
7. Do you provide installation instructions or technical support?
Yes, we provide detailed installation drawings and a user manual. Our technical team is available to answer questions via email or phone. For large projects, onsite guidance may be arranged separately.
8. Can I get a sample before mass production?
Yes, we accept sample orders. The sample cost will be deducted from the final order quantity. Please note that customization may apply to samples as well.
