The skin of the non-metallic fabric compensator is its core component and is used to absorb displacement in the piping system, including thermal expansion, shock, and mechanical motion, while providing sealing and protection. Non-metallic skins are typically composed of multiple layers of different non-metallic materials composite to accommodate various working environments such as high temperatures, corrosive media, and high pressures.
Main material
The constituent materials of the non-metallic skin may include:
Glass fiber cloth: Provides structural strength and temperature resistance.
Aluminum silicate fiber: Increase high temperature resistance.
Silicone cloth: It can be used in lower temperature environment, and has better flexibility and chemical resistance.
Fluoroadhesive: Suitable for higher temperatures and harsh environments with excellent heat resistance and corrosion resistance.
Polytetrafluoroethylene (PTFE) film: Improve corrosion resistance and slipability.
Alkali-free glass fiber cloth: Strengthens the structure and reduces alkaline corrosion.
Stainless steel wire mesh: Provides additional structural support and protection.
Structural characteristics
Multi-layer design: The skin is usually composed of 6-8 or more layers of material composite, each with its specific function, such as temperature resistance, sealing, reinforcement, or protection.
Hemming treatment: The edges are specially treated for enhanced sealing and durability.
Non-metallic soft connection: The expansion part is made of cloth material, and there is no elastic deformation reaction force of the metal compensator, so the force requirement of the support is small.
Performance Benefits
Wide temperature resistance range: Depending on different material combinations, it can be applied in the temperature range from low temperature to up to 1200°C.
High pressure resistance: Can withstand high working pressure.
Strong corrosion resistance: Suitable for a variety of corrosive media.
Good flame retardant property: It has good fire resistance.
Sound absorption and shock absorption: It can absorb vibration and reduce noise.
Good flexibility: Ability to accommodate minor displacements and shape changes of pipes.
Areas of Application
Non-metallic fabric compensator is widely used in electric power, chemical industry, iron and steel, cement, environmental protection and other industries, especially suitable for flue, ventilation duct, fan inlet and outlet, hot air duct and other occasions that need large displacement compensation and sealing.
When designing and selecting a non-metallic fabric compensator skin, it is necessary to determine the most suitable material combination and structural form according to specific working conditions, such as temperature, pressure, medium characteristics, displacement type, etc. Manufacturers often offer customized services to meet the specific needs of different customers.
