The main materials for flexible connections of air ducts are diverse, each with its unique characteristics and applicable scenarios. The following is a detailed summary of the main materials used for air duct soft connections:
1. Canvas material
Characteristics: Canvas soft connections are usually made of artificial fiber canvas, fiberglass canvas, ceramic fiber canvas, etc., which have advantages such as long service life, acid resistance, alkali resistance, oil resistance, corrosion resistance, moisture resistance, light volume, and convenient installation. Some canvas soft connections have also undergone fire-resistant treatment to meet specific safety requirements.
Applicable scenarios: Canvas soft connections are suitable for general ventilation systems and smoke exhaust systems, especially in situations where wear resistance, acid and alkali corrosion resistance are required. However, for high-temperature environments or situations that require higher fire resistance ratings, other materials may need to be selected.
2. Rubber material
Characteristics: The rubber soft connection is made by compounding rubber and high fiber fabrics (such as polyester canvas, aramid canvas), which have good elasticity and heat resistance. According to different media, different rubber materials are used, such as styrene butadiene rubber, butyl rubber, nitrile rubber, EPDM rubber, etc., which have functions of heat resistance, acid resistance, alkali resistance, corrosion resistance, wear resistance, oil resistance, etc.
Applicable scenarios: Rubber soft connections are suitable for environments that require high sealing and durability, such as high-temperature, high-pressure, or corrosive gas delivery systems.
3. Stainless steel material
Features: The stainless steel soft connection is made of stainless steel sheet, which has high strength, corrosion resistance, and high temperature resistance. Its corrugated pipe structure can compensate for the thermal and mechanical deformation of the pipeline, absorb vibration and noise.
Applicable scenarios: Stainless steel flexible connections are suitable for harsh environments and systems that require long-term stable operation, such as high-temperature, high-pressure, or corrosive media transmission pipelines in industries such as chemical, petroleum, and power.
4. Silicon titanium alloy material
Features: The soft connection of silicon titanium alloy is made of silicon titanium alloy cloth, which has the characteristics of fire resistance, high temperature resistance, acid and alkali corrosion resistance, etc. Its fire rating and high temperature resistance are superior to ordinary canvas soft connections.
Applicable scenarios: Silicon titanium alloy soft connections are suitable for transportation systems of high temperature, high pressure, or corrosive gases, especially in situations where high fire protection levels are required.
5. Fabric fiber material
Characteristics: The fabric fiber soft connection is made of glass fiber cloth, silicone cloth, etc., and has the characteristics of high temperature resistance, corrosion resistance, and good flexibility. Some fabric fibers have undergone special treatment to enhance their fire resistance.
Applicable scenarios: Fabric fiber soft connections are suitable for high-temperature environments, such as environments with temperatures up to 1300 ℃, and can still be used. Meanwhile, it is also suitable for ventilation systems that require wear resistance and corrosion resistance.
6. Plastic material
Characteristics: Plastic flexible connections are usually made of materials such as PVC and PU, which have the characteristics of light weight, corrosion resistance, and easy processing and molding. However, its high temperature resistance and strength are relatively low.
Applicable scenarios: Plastic flexible connections are suitable for ventilation systems or temporary ventilation situations that do not require high temperature resistance and require corrosion resistance.
