plastic duct introduction
plastic duct also known as PP plastic air duct, plastic ventilation duct. PP air ducts chemical resistance are usually used for the exhaust of corrosive exhaust gas in the environment of industrial plants, the exhaust of fume hoods in the laboratory, and the exhaust of VOC organic exhaust gas. Also often used for hydroponics or organic vegetable growing.The advantages of PP air ducts are light weight, acid and alkali corrosion resistance, hot melt welding with PP electrodes, and easy processing and installation of fittings such as elbows, flanges, tees, and reducing diameters. It is currently the most widely used in waste gas treatment in the environmental protection industry.
plastic duct installation method
PP duct socket connection, that is, a PP sleeve is welded at the end of each air duct to facilitate the insertion of the next air duct;
PP air duct and air duct flange connection, that is, a PP flange is welded at both ends of each air duct, and the screw-to-lock connection is used during installation.
The strengthening method of PP air duct, in industrial exhaust, in most cases, the end centrifugal fan is used to exhaust air, and the negative pressure is formed in the PP air duct, and the industry design specification stipulates the required wall thickness of the PP air duct at a certain wind speed. And the strengthening method, usually the PP air duct is reinforced by the outer flange, such as a 3-meter-long air duct, which is reinforced with 2 flanges, which is beautiful and durable. The large square air duct is reinforced by the outer flange, and the internal PP circular pipe is used for structural support.
plastic pipe fresh air system structure
In order to form a complete PP anti-corrosion pipeline system, in addition to PP air ducts, it is not enough to have PP air duct accessories, which can be combined with the installation to form a complete anti-corrosion acid and alkali-resistant exhaust air pipeline system.
