PP Round Ducts

Round PP duct is the standard cross-section for polypropylene ventilation systems: circular profiles give even airflow distribution, lower pressure loss and simple welding to fittings. XICHENG’s round duct range covers polypropylene round ducts, PP air ducts, exhaust ducts, flame retardant duct and custom fabricated sections, in beige or grey.

Sizes and Specifications

Standard round duct is manufactured in φ20-500mm, hot air welded from PP sheet and joined by flange or socket connection. The material resists acids and alkalis across pH 1-14, operates from -15°C to 80°C, and the same PP grade can be specified across duct, fittings and accessories so a complete system is made from one material.
