SS304 SS316 Metal Bellows DN50 - DN1200 Metal Expansion Joint PN10 PN16 ANSI DIN

A bellows is a tubular structure with a corrugated shape, usually made of metal or plastic. It has high flexibility and elasticity, and can withstand large pressure and deformation. Bellows are widely used in various fields

Working principle
The core component of the bellows compensator is the bellows, which is an element with elastic expansion and contraction function. When the pipeline system is displaced due to thermal expansion and contraction or other factors, the bellows can absorb these displacements through its own elastic deformation, thereby reducing the deformation stress of the pipeline system. For example, the internal pressure bellows compensator absorbs the thermal expansion of the pipeline by compressing the corrugations, while the external pressure bellows compensator absorbs the thermal expansion by stretching the corrugations.

Structural composition
The bellows compensator is usually composed of bellows, end pipes, brackets, flanges, conduits and other accessories. The bellows is its core component, has good elasticity and sealing, and can remain stable under different working environments. In addition, the connection methods of the compensator are divided into flange connection and welding.
Advantages

• Strong compensation ability: can absorb displacement in multiple directions, including axial, lateral and angular.
• Vibration reduction and noise reduction: can effectively reduce the vibration and noise of the pipeline system.
• High temperature and corrosion resistance: suitable for a variety of harsh working environments.
• Easy installation: simple structure, low installation and maintenance costs.

High elasticity and flexibility: Bellows can withstand large bends and twists without breaking or damaging, which makes it ideal for use in applications that require frequent movement or bending. Pressure resistance: Bellows can withstand high internal pressures and are suitable for the delivery of high-pressure fluids or gases. Corrosion resistance: Bellows made of certain materials have good corrosion resistance and can be used in chemical liquids or corrosive environments. Temperature resistance: Bellows can be designed to withstand extreme temperatures, from very low temperatures to high temperature environments. Shock and noise reduction: Bellows can absorb vibrations and reduce noise, and are suitable for occasions where shock and noise reduction are required. Easy to install and maintain: Bellows are usually designed to be easy to install and maintain, reducing installation time and costs.

The bellows compensator is widely used in the following fields:
Water supply system: used to compensate for the expansion and contraction of the pipeline due to temperature changes to ensure the stable operation of the pipeline system.
Chemical pipeline: suitable for the transportation of high temperature, high pressure and highly corrosive chemical media.
Hot air pipeline and smoke pipeline: used to absorb the thermal expansion and vibration of the pipeline.
Industrial and civil buildings: used for pipelines for conveying various liquids, gases and chemicals.
