First, the application of PVC ventilation pipe

1. Industrial field

Factory workshop: eliminate exhaust gases and dusts (such as welding fumes and chemical gases) generated in the production process.

Laboratory: fume hood, exhaust system to ensure that harmful gases (such as acid mist, organic solvents) are discharged in time.

Food processing: moisture-proof ventilation to avoid mold growth and meet hygienic standards.

2. Civil field

Building ventilation: Fresh air system in basements and parking lots to prevent moisture and CO build-up.

Agricultural greenhouses: regulate temperature and humidity and promote air circulation.

3. Special environment

Corrosion-resistant scenarios: corrosive gas environments such as chemical and electroplating plants replace metal pipelines.

Second, the application of PVC dust pipe

1. Industrial cleaning

Woodworking workshop: connect to the vacuum equipment to collect wood chips and dust, and the anti-static model can avoid sparks.

Metal processing: Suck up metal chips, strong wear resistance.

2. Commercial/Residential

Central vacuum system: building cleaning, hotel cleaning, light and easy to install.

Car Vacuum Cleaner: Flexible PVC pipe adapts to tight spaces.

3. Special needs

Cleanroom: Anti-static pipes are used in electronics factories to prevent dust adsorption.

3. Advantages and limitations

Advantage:

Low cost, light weight (only 1/5 of metal pipe), easy to install.

No rust, corrosion resistance, long life of 10-15 years.

The surface is smooth, the fluid resistance is small, and it is not easy to accumulate dust.

Limitations:

Poor high temperature resistance, easy to deform more than 80°C (CPVC can be selected to increase to 90°C).

UV sensitivity (anti-UV agent is required for outdoor use).

Fourth, the selection of suggestions

Ventilation ducts: Priority is given to corrosion resistance classes (e.g., ASTM D1784 Class series) and diameter (airflow requirements).

Vacuum pipe: Pay attention to the thickness of the wear layer (e.g. more than 1.5mm) and antistatic certification (e.g. ISO 8031).

Through reasonable selection, PVC pipes can efficiently meet the needs of ventilation and dust removal, balancing economy and functionality.
