PP Square Plastic Tube is processed from PP polypropylene sheet, which is a semi-crystalline material. It is harder and has a higher melting point than PE. Since homopolymer PP is very brittle at temperatures above 0°C, many commercial PP materials are random copolymers with 1 to 4% ethylene added or pinched copolymers with higher ethylene content. The copolymer-type PP material has a lower thermal distortion temperature (100 ° C), low transparency, low gloss, low rigidity, but has a stronger impact strength.
]]> Plastic square pipe, also known as polypropylene plastic air duct, is used for laboratory exhaust air exhaust. PP Square Plastic Tube usually uses PP round air duct as the main pipe and branch pipe. PP Square Plastic Tube is made of PP sheet through a bending machine, folded four times at a 90-degree elbow and then hot-melt welded. There are many processes. Compared with the square tube of the same circumference or cross-section, the price of the square tube 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.

PP Square Plastic Tube

Features of plastic square pipe

  • No rust: Plastic square pipe can withstand the corrosion of PH value in a wide temperature range and high concentration of acid and alkali in the range of 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: The PP piping system has a lifespan of 50 years under the specified conditions of use. Long service life—–The PP pipeline 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.

How PP Square Plastic Tube Strengthens

In industrial exhaust, in most cases, the end centrifugal fan is used to draw air, and the pipeline forms a negative pressure, and the industry design specification stipulates the wall thickness and reinforcement method of PP Square Plastic Tube at a certain wind speed, usually square PP The large square air duct is reinforced by the outer flange, and the internal PP circular pipe is used for structural support.
