PP material duct / Grey

Duct is piping for air transportation and distribution. In the chemical, food, and other industries, ventilation piping systems have become increasingly demanding, metal duct, chemical resistance, hygiene and economic effect than has lagged far behind the plastic duct. Plastic duct in order to propylene (PP, FRPP, PPH) Duct largest proportion. Duct Category: PP duct is piping for air transportation and distribution. In the chemical, food, and other industries, ventilation piping systems have become increasingly demanding, metal duct, chemical resistance, hygiene and economic effect than has lagged far behind the plastic duct. Plastic duct in order to propylene (PP, FRPP, PPH) duct pp tube specifications: diameter of 400 or less is forming a tube wall thickness: 2-6mm ranging from 5 m long one, the middle two flanges strengthen , solid, diameter above 400 for manual processing tube, length according to actual customer needs, and the appearance of rice gray, smooth and nice. The largest proportion. pp tube specifications: diameter of 400 or less is forming a tube wall thickness: 2-6mm ranging from 5 m long one, the middle two flanges strengthen, secure, diameter 400 or more for the manual processing tube length according to actual needs of customers given the appearance of rice gray, smooth and nice. According to the cross-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 works, the circular duct high efficiency, low operating cost, light weight and convenient transportation and installation, usage is increasing.
