Send Lipu produce quality PPH, PVC duct

PPH Duct Profile: PPH is mainly used for exhaust ventilation duct pipe, duct because of their role in their general appearance large diameter, wall thickness PPH is a high molecular weight, low melt index polypropylene homopolymer, since the material After modification, having a uniform fine crystal structure, so that it not only has excellent chemical resistance, temperature resistance and excellent creep resistance, and at low temperatures also has excellent impact resistance. In the 1980s PPH material on applied pressure piping systems, currently used in good condition. PP-H pipe performance features include: excellent corrosion resistance, especially prominent is the long-term creep resistance and resistance to stress cracking resistance, excellent pressure resistance, resistance to surface wear and ease of welding (welding property). PPH duct effect: wind pipe is the pipe for air transportation and distribution. In the chemical, food, and other industries, ventilation pipe system is relatively high, before the metal duct, the economic effect than has lagged far behind the plastic duct. Plastic duct in order to propylene (PP, FRPP, PPH) Duct largest proportion. PPH duct Category: follow-sectional shape is divided into: round duct, rectangular duct, flat circular and other kinds, including circular duct of least resistance, less leakage, small footprint, have been tested throughout the ventilation project high efficiency circular duct, low operating costs, so round duct usage is increasing.
