Metal Hydraulic-Formed Bellows

Metal Hydraulic-Formed Bellows applications are widespread across key areas of modern industry:

Key Industrial Fields: Compensation and Vibration Damping

This is the most traditional and core application.

Petrochemicals and Oil Refining: Used in large pipelines, furnace outlets, reactor inlets and outlets, etc., to absorb thermal displacement and protect equipment connections. It acts as a "safety key" for the safe operation of installations.

Power Industry:

• Thermal Power: Boiler outlets, steam turbine inlets, flue and air duct systems, compensating for the expansion of high-temperature flue gas pipelines.
• Nuclear Power: Used in auxiliary pipelines in nuclear and conventional islands, requiring extremely high reliability and sealing performance.
• Iron and Steel Metallurgy: Blast furnaces, hot blast stoves, converter gas and hot blast pipelines, operating in high-temperature, dusty environments.
• Shipbuilding and Offshore Engineering: Naval vessel engine exhaust systems, subsea pipeline compensation, requiring resistance to seawater corrosion and vibration.

Aerospace:

• Engines: Used as flexible connecting pipes for fuel, hydraulic, and lubricating oil systems, compensating for installation displacement and vibration.
• Flight Control Systems: Connecting actuators to transmit hydraulic power.
• Spacecraft Propulsion Systems: Connecting fuel pipelines and compensating for thermal deformation.

Semiconductor Manufacturing:

Transporting ultra-high-purity gases and chemicals. The bellows itself has high cleanliness and can compensate for minute displacements between precision equipment.

Vacuum Equipment:

Serving as flexible connectors between vacuum flanges, which is a crucial component for achieving chamber movement, alignment, or vibration isolation. This is a very important and unique application.

Instruments and Sensors:

• Pressure/Temperature Sensor Sensing Elements: Pressure causes displacement of the bellows, which is converted into electrical signals.
• Sealing Elements: Used for valve stem sealing (e.g., bellows seal valves), achieving zero leakage, suitable for toxic or flammable media.

Medical and Food Equipment:

Bioreactors, pharmaceutical pipelines, and food processing equipment requiring high hygienic standards for flexible connections.

Low-Temperature Engineering:

Compensation for LNG (liquefied natural gas) storage tanks and pipelines, requiring materials with excellent low-temperature toughness.
