Fabric Expansion Joint/Non-metallic Expansion Joint

Product Description

Fabric Expansion Joint, also known as Non-metallic Expansion Joint, is a flexible pipeline connection component designed to absorb thermal expansion, vibration, and mechanical displacement in industrial duct systems. It is mainly composed of high-temperature resistant fabric materials, insulation layers, and flexible sealing structures, providing excellent flexibility and corrosion resistance.

Unlike traditional metal expansion joints, non-metallic expansion joints can withstand large movements while effectively reducing vibration and compensating for installation deviations. They are widely used in flue gas systems, power plants, cement plants, steel mills, chemical industries, and environmental protection equipment.

Key Features

Excellent Flexibility
Provides multi-directional movement compensation, including axial, lateral, and angular movements.

High Temperature Resistance
Special fabric materials can withstand high-temperature gases and harsh operating environments.

Corrosion & Chemical Resistance
Suitable for corrosive gases, dust, and chemical media in industrial processes.

Vibration Reduction
Effectively absorbs mechanical vibration and reduces stress on connected equipment.

Lightweight Structure
Compared with metal expansion joints, it has lower weight and easier installation.

Custom Design Available
Manufactured according to duct dimensions, temperature, pressure, movement requirements, and working conditions.
