PP ducts are core components for conveying corrosive exhaust gases in exhaust treatment systems. Made of polypropylene, they are widely used in industries such as chemical, electroplating, electronics, and pharmaceuticals.
They offer five key advantages: First, they are highly corrosion-resistant and non-reactive with acids, alkalis, and salts, addressing the corrosion challenges of traditional metal ducts. Second, they are lightweight and easy to install, with a density only 1/5-1/8 that of metal, eliminating the need for heavy equipment and enabling convenient splicing. Third, they offer low resistance and high efficiency, with a smooth interior (roughness 0.01mm) that reduces airflow pressure loss. Fourth, they are stable and durable, with no aging or deformation within temperatures between -10°C and 80°C, and no harmful substances are released. Fifth, they are cost-effective, with procurement costs lower than stainless steel ducts, require no regular anti-corrosion maintenance, and have a lifespan of 8-15 years.
