Product Role
1. Connection: Flanged metal hose can connect pipes and equipment of different sizes or types between pipes and equipment to achieve flexible connection of pipelines.
2. Buffering effect: It can buffer the vibration and impact of the pipeline during normal operation, prevent the stress concentration caused by the expansion or deformation of the pipeline, so as to prolong the service life of the pipeline and equipment.
3. Compensation: Through the expansion and contraction deformation of the bellows, the changes in temperature, vibration or installation error of the pipeline are compensated to ensure the normal operation of the pipeline system.
Product structure features
Flanged metal hoses are made of stainless steel or other corrosion-resistant metal materials and are typically connected to the piping system by flanges at both ends. Its structure is composed of inner and outer layers: the inner layer is a metal bellows, which is responsible for transferring the fluid medium; the outer layer is reinforced by a mesh structure with good compressive and tensile properties.
Product application scenarios
1. Petrochemical industry: It is used to transport corrosive media with high temperature and high pressure to ensure the smooth flow of fluids, and to prolong the life of the equipment by absorbing shock and absorbing the displacement of thermal expansion and contraction.
2. Building and HVAC system: Next to the equipment with strong vibration, reduce the vibration transmission of the equipment and ensure the smooth operation of the system.
3. Ship and marine engineering: When the ship equipment is in operation, the vibration is large, and the flanged metal hose can effectively reduce the vibration and noise.

Product installation steps
1. Check the hose and flange
2. Clean the pipe interface
3. Install the clamp
4. Connect the hose to the pipe
5. Check the installation quality
Maintenance of the product
1. Avoid twisting: Twisting of the metal hose should be avoided during installation, otherwise its service life will be significantly shortened.
2. Regular inspection: Regularly check whether the bolts, washers and other components at the flange connection are loose or damaged to ensure the sealing performance of the hose.
3. Replacement cycle: Replace the metal hose regularly according to the use environment and frequency to avoid the reduction of material toughness due to long-term exposure to high temperature, acid and alkali and other harsh conditions.
