KFT Type High-Temperature Duct Rubber Expansion Joint
The official website of Shanghai Songjiang Vibration Absorber Group Co., Ltd. introduces information about KFT Type High-Temperature Duct Rubber Expansion Joint. Songjiang Group recommends high-temperature duct rubber expansion joints for high-temperature fans. These joints can withstand temperatures up to 200 degrees Celsius and are produced using silicone rubber, effectively preventing damage to chimneys caused by fan vibrations.
Songjiang Group’s duct rubber expansion joint is composed of rubber and fiber fabric composite materials, steel flanges, and steel restraining rods. It is mainly used for flexible connections between various fans and air ducts. Its functions include shock absorption, noise reduction, sealing, medium resistance, easy displacement, and installation. It is the ideal choice for shock absorption, noise reduction, and smoke and dust elimination in the field of environmental protection.
The duct rubber expansion joint has excellent repeatability in displacement (variation), providing substantial multi-dimensional compensation within a small size range. It effectively eliminates multi-directional errors that may occur during the installation and connection of various pipelines.
The duct rubber expansion joint possesses superior sound absorption and isolation capabilities, effectively reducing and eliminating the transmission of noise and vibrations in systems such as boilers and fans.
The transmission loss of rubber and fiber fabric minimizes design complexity, eliminating the need for additional auxiliary facilities.
The rubber, fiber fabric, and thermal insulation materials exhibit high heat resistance and corrosion resistance, never rusting, thereby reducing maintenance costs.
The duct rubber expansion joint demonstrates outstanding airtightness and flexibility, ensuring no leakage of conveyed media and the restoration of its original state after repeated displacement.
Brief Installation Instructions for Duct Rubber Expansion Joint:
1.The installation length is determined by the user during the design phase. If not specified during ordering, it will be supplied with an installation length of L=350mm.
2.The weight in the table is calculated based on a typical installation length of L=350mm.
3.The duct rubber expansion joint has a support frame in the middle. The support frame should be kept in place before installation. After tightening the bolts, remove the support frame completely to ensure a proper installation and allow the various physical and mechanical properties to function effectively.
The duct rubber expansion joint offers a choice of three rubber materials: natural rubber, EPDM rubber, and silicone rubber. The temperature resistance for each type of rubber is as follows: natural rubber is suitable for temperatures below 80 degrees Celsius, EPDM rubber for temperatures below 120 degrees Celsius, and silicone rubber for temperatures below 200 degrees Celsius.
