In industrial and commercial buildings, air ducts are a key component in the delivery and removal of air. PP plastic air duct and galvanized air duct are two common air duct materials, each with unique characteristics and advantages. This article will discuss the differences between PP plastic air ducts and galvanized air ducts in detail, and analyze their applicable scenarios to help you make informed decisions when choosing the appropriate air duct material.
PP plastic air duct
Advantages of PP plastic air duct:
- Corrosion resistance: PP plastic air duct has good corrosion resistance to various chemical substances and corrosive gases, and is suitable for humid environments and places with more corrosive gases.
- Lightweight and easy to install: Compared with galvanized air ducts, PP plastic air ducts are lighter and easier to carry and install. It adopts splicing connection without welding and fixing, and the installation is simple and efficient.
- Insulation performance: PP plastic air duct has good insulation performance and is non-conductive. It is suitable for occasions that need to avoid static electricity accumulation or reduce heat loss.
- Energy saving: Due to the lower thermal conductivity, PP plastic air ducts have less heat transfer loss than galvanized air ducts, providing higher energy efficiency, saving energy and reducing operating costs.
- Long-term reliability: PP plastic air ducts are corrosion-resistant, rust-free, have a long service life, and are not affected by the growth of mold, fungus, and microorganisms.
Disadvantages of PP plastic duct:
- Temperature limitation: PP plastic ducts are weak in high temperature environment, may be deformed or melted, and are not suitable for high temperature discharge.
- Lower mechanical strength: Compared with galvanized air ducts, PP plastic air ducts have lower mechanical strength and are susceptible to physical damage.
Applicable scene:
- Corrosive gas discharge: PP plastic air duct is very suitable for corrosive gas discharge places such as chemical industry and acid and alkali plants.
- Ventilation and air conditioning system: PP plastic ducts can be widely used in commercial buildings, hospitals, laboratories and other places that require ventilation and air conditioning systems.
- Places with high environmental protection requirements: Since PP plastic air ducts do not emit harmful substances such as lead and cadmium, they are suitable for places with high environmental protection requirements, such as food processing factories, pharmaceutical factories, etc.
Galvanized air duct
Advantages of galvanized air duct:
- High temperature resistance: Galvanized air ducts can maintain structural stability and durability in high temperature environments, and are suitable for high temperature discharge occasions.
- Higher mechanical strength: Compared with PP plastic air duct, galvanized air duct has higher mechanical strength and can resist certain physical impact and pressure.
- Wear resistance: The surface of the galvanized air duct is covered with a zinc layer, which has good wear resistance and can adapt to harsh working environments.
Disadvantages of galvanized air duct:
- Corrosion risk: Galvanized air ducts may have the risk of zinc layer corrosion or rust after long-term use, especially in humid or corrosive gas environments.
- Complicated installation: Galvanized air ducts need to be welded and fixed, and the installation process is relatively complicated, requiring more time and labor costs.
Applicable scene:
- High-temperature environment: Galvanized air ducts are suitable for industrial places that need to discharge high-temperature gases, such as metallurgy, boilers, etc.
- Places with high mechanical impact: The high mechanical strength of galvanized air duct makes it suitable for environments that need to withstand mechanical impact, such as factory workshops, mining sites, etc.
PP plastic air ducts and galvanized air ducts have their own advantages and applicable scenarios in different aspects. PP plastic air duct is suitable for corrosive gas discharge, ventilation and air conditioning systems and places with high environmental requirements. The galvanized air duct is suitable for high temperature environments and places requiring higher mechanical strength. When selecting the material of the air duct, it should be comprehensively considered according to the specific working environment, corrosion resistance, mechanical strength and temperature requirements, so as to ensure that the most suitable material for the air duct is selected to meet the requirements of the air duct.
