Overview
The Fire Resistant Anti-Static PVC Spiral Mine Flexible Duct is a high-performance ventilation ducting solution designed for extremely harsh and high-risk environments such as mines and tunnels. Combining flame retardancy, anti-static properties, high wear resistance, and flexibility for easy installation, it ensures continuous and safe air circulation for underground operations. It is crucial infrastructure for protecting miners' lives and the normal operation of production equipment.
Traditional ventilation ducts are prone to wear and static sparking in mines, and lack flame retardancy, posing significant safety risks. This product utilizes a specially formulated PVC (polyvinyl chloride) coating applied to high-strength polyester fiber and features an internal spiral steel wire skeleton for support. This ensures the duct remains resistant to collapse even under negative pressure, maintaining smooth ventilation.
Advantages
Use high quality raw materials to ensure product quality;
Being engaged in the field of ventilation system for more than 30years, have rich experience in ventilation design;
Cooperate with several research institutes and have the latest technology;
Several automatic ducting welding production lines with a monthly output of 20,000 flexible ventilation tubes with assured batch order lead time;
PVC spiral tubes are available in custom sizes to ensure a perfect fit for your requests;
The spiral ventilation duct is coupled with zipper and Velcro. The extra fabric on which the zipper/Velcro is sewed is welded to the flexible duct body to ensure that there are no sewing needle eyes throughout the ducting, reducing air leakage.
