The design is beautiful, the installation is simple, and it can be customized freely.]]> The PP plastic air duct is also called polypropylene plastic air duct, which is used for exhaust gas exhaust in the laboratory. The square PP duct is usually used as the main duct and branch duct with the PP circular duct. The square PP air duct is made of PP sheet through a bending machine, four times of 90-degree elbows, and then hot-melt welding. There are many processes. Compared with square ducts, the price of square ducts is higher for round ducts with the same circumference or cross-section. Of course, it also depends on the wall thickness of the square PP duct and whether it is reinforced by the outer flange.

Features of square PP plastic air duct

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

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 pincer 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.]]> High Performance Round PP Plastic Air Duct | Polypropylene Ventilation Pipe

$4.00 – $12.00

SKU: Customizable per size & technical requirements

We manufacture our round PP plastic air duct from virgin polypropylene (PP) material. Specifically, it features excellent resilient property and targets durable, corrosion-resistant ventilation in industrial exhaust systems. Furthermore, we offer fully customizable sizes and free drawing design for all projects.

Core Advantages of Our PP Polypropylene Air Duct

  • Superior Chemical Resistance: We design this duct with excellent acid & alkali corrosion resistance, so it avoids secondary chemical reactions with exhaust media and perfectly adapts to corrosive industrial environments.
  • High Performance & Durability: Notably, it delivers high resilience, strong rigidity and UV resistance. It operates within a temperature range of -10°C to 80°C and offers a service life of up to 50 years.
  • Easy Installation & Processing: In addition, it weighs only 1/7 of steel ducts, which simplifies transportation and installation. We also make it compatible with hot melt welding, so it seamlessly matches elbows, flanges, tees and other ventilation fittings.
  • Fully Customizable: Moreover, we support custom diameters, wall thickness and colors to fit different project needs, and we provide free technical consultation for all inquiries.
  • Wide Application: For example, it works ideally for industrial plant corrosive exhaust, laboratory fume hood extraction and VOC organic waste gas treatment systems.

Installation & Reinforcement Methods

Standard Connection Methods

  1. Socket Connection: We weld a PP sleeve at the end of each duct for seamless insertion, which ensures excellent air tightness.
  2. Flange Connection: Alternatively, we weld PP flanges at both ends of each duct, and your team can lock them with screws during installation. This method suits large-diameter duct systems best.

Duct Reinforcement Solution

To ensure stable performance in negative-pressure industrial exhaust systems, we reinforce our PP air ducts with outer flanges in strict accordance with industry design specifications. For instance, we add 2 outer flanges to a 3-meter-long duct for enhanced structural stability. For large square ducts, we combine outer flange reinforcement with internal PP pipe structural support.

Complete PP Anti-Corrosion Pipeline System

To form a fully functional exhaust system, our round PP air ducts can be matched with a full range of PP ventilation accessories, including elbows, tees, reducers, flanges, dampers, air valves and more. We provide one-stop solutions for your entire anti-corrosion, acid and alkali resistant exhaust pipeline system.
