Product Description

Square PP air duct, also known as polypropylene plastic air duct, is used for laboratory exhaust air exhaust. Square PP air ducts are usually used as main pipes and branch pipes using PP round air ducts. The square PP air duct is made of PP sheet after bending the 90-degree elbow four times and then hot-melt welding. There are many processes. Compared with the square pipe with the same circumference or cross-section, the price of the square pipe is higher. , Of course, it depends on the wall thickness of the square PP air duct and whether it is reinforced with an outer flange.

Features of square PP air duct

No rust: The square PP air duct can withstand the corrosion of PH value in a wide temperature range and high concentration of acid and alkali ranging from 1 to 14.
Wear resistance and no scaling: The inner wall of PP pipes and fittings is uniform and smooth, with low flow resistance and no scaling.
Reduce vibration and noise: PP pipes have excellent sound insulation properties, which can significantly reduce vibration and noise caused by liquid flow.
Anti-freeze crack: PP material has excellent elasticity, so that the pipe and pipe section can expand with the frost heaving liquid without bursting.
Anti-condensation, less heat loss: PP material is a poor thermal conductor, which can reduce condensation and reduce heat loss.
Simple installation: PP pipes are light in weight, easy to install and operate, and have weldability.
Long service life: PP piping system has a lifespan of 50 years under the specified conditions of use. Long service life-----The PP pipe can be used safely for more than 50 years under the condition of rated temperature and pressure.
Excellent corrosion resistance----can withstand the corrosion of most chemicals, and can withstand the corrosion of high concentrations of acids and alkalis with a pH value of 1-14 in a wide range.
Excellent anti-wear performance-----When transporting ore mud, the wear resistance of PP pipe is more than 4 times that of steel pipe.
Good hygienic performance-----PP pipe material has only carbon and hydrogen elements in its molecules, which is non-toxic and tasteless, and has reliable hygienic performance.
Heat-resistance, heat-insulation and energy-saving-----PP pipes have a maximum use temperature of about 95 degrees. The thermal conductivity of this product is only 1200 of that of steel pipes, so it has better heat preservation performance.
 

PP square air duct specifications are:

• If the single side length is less than 250mm, manual panel splicing is required, and the minimum range of the bending machine is
• Single side length greater than 250mm can be processed by bending machine, common sizes are 250x320 320x400 400x630 600x830, etc.

Square PP duct connection method

• Socket type connection, that is, a PP sleeve is welded at the end of each air duct to facilitate the insertion of the next 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.
