PP duct are used for a variety of building materials needs. The scientific name of PP duct engineering plastic is polypropylene air pipe, which is another excellent resin variety developed after nylon. PP duct has excellent solvent resistance, oil resistance, weak acid resistance, weak alkali resistance and other functions. POM has high hardness and rigidity, high creep resistance and stress relaxation ability, excellent wear resistance, self-lubrication, and fatigue properties, which are incomparable with other engineering plastics.
In addition to its excellent physical and chemical characteristics, PP duct is convenient to install in the process of engineering construction. (On-site can be used: hot melt butt welding, socket welding and flange connection three methods) not only low cost, light weight. Also the product has good temperature resistance (below 100°C), compression resistance, tensile resistance and bending resistance. Whether it is buried underground or laid in the air, it has a long service life and has long been used in the fields of chemical fiber, papermaking, pharmaceuticals, food, sewage treatment, chemical industry, metallurgy, mining, and building water supply and drainage.
The PP duct itself has high strength, bending resistance and tensile strength. Dilute sulfuric acid is also very good for hydrochloric acid, food, and temperature resistance, and can withstand corrosive media up to 90 degrees Celsius. The outer diameter of the PP pipe is De25-1200mm; in addition to concentrated nitric acid, oleum, the wall thickness of the pp duct is 2-28mm; the pp duct is a good anti-corrosion duct, chemical fiber industry, hydrofluoric acid, dilute nitric acid.
Polypropylene ducts are widely used in industrial ventilation and laboratory ventilation. Because the cost of construction is lower than that of PVC air ducts and stainless steel air ducts, it is a new type of air duct that is very cost-effective at present. A new generation of flame retardant air ducts has been developed for fire safety polypropylene air ducts, which can prevent the spread of fire sources in high temperature combustion environments.
The product performance of PP air ducts is very mature, with various sizes and specifications, and supports customization of various sizes.
