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.

It is more hard than PE and has a higher melting point. Due to the high crystallinity, the surface of the material stiffness and resistance to scratch characteristics very well. PP don’t have the problem of environmental stress cracking. Moreover, it could offer significant resistance to any chemical or acid. PP pipe is a kind of plastic pp made of copolymerized polypropylene resin and extruded. It has light weight, good chemical stability, heat resistance, insulation, high mechanical strength and non-toxic.At present, the PP pipe connection mode widely used in construction is:1. welding sleeve socket welding method 2End edge welding method. 3. dissimilar material take over: used in petroleum, chemical, chlorine alkali, dye, agriculture, food, medicine, light industry, metallurgy, waste water treatment, water supply and drainage, etc.

No corrosion: PP 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 resistance and non-scaling: The inner wall of the PP duct and pipe fittings is uniform and smooth, with low flow resistance and no scaling.

Reduce vibration and noise: PP air duct has excellent sound insulation performance, which can significantly reduce vibration and noise caused by liquid flow.

Anti-freeze cracking: The material used in the PP duct is excellent in elasticity, so that the pipe and pipe section can expand with the frost heaving liquid without bursting and cracking.

Anti-condensation, low heat loss: The material used in the PP duct is a poor thermal conductor, which can reduce condensation and reduce heat loss.

Simple installation: PP air duct is light in weight, easy to install and operate, and has weldability.

Long service life: The PP duct has a service life of up to 50 years under the specified temperature, pressure, medium and other use conditions.
