VOC Waste Gas Treatment

This system is a dedicated environmental protection equipment tailored for API 5CT tubing threading processes. Targeting VOC waste gas, oil mist, and dust generated during threading, anti-rust oil coating, and drying stages, it adopts a combined process of pre-treatment + adsorption concentration + catalytic combustion to ensure emissions comply with national environmental standards and adapt to the intermittent production rhythm of industrial lines.
