SS Metal Bellows Expansion Joints With CL150 PN16 PN25

SS METAL BELLOWS EXPANSION JOINT WITH CL150 PN16 PN25

Metal expansion joints are compensating elements for thermal expansion and relative motion in pipelines, containers, and machines.
Depending on the application, they are composed of one or more metal corrugated pipes, connectors at both ends, and pull rods.
They differ based on three basic types of motion: axial, angular, and lateral expansion joints. Expansion joints are used in various fields
such as energy production, papermaking industry, chemical industry, water treatment, oil and natural gas. Expansion joints can be used
regardless of thermal motion or vibration in the pipeline.

What applications are metal expansion joints commonly used in?

Metal bellows and expansion joints are commonly used in a variety of applications to compensate for thermal expansion, vibration, misalignment, and other types of movement in pipelines and equipment. Here are some common applications for metal bellows and expansion joints:

•HVAC systems: Metal bellows and expansion joints are used in heating, ventilation, and air conditioning (HVAC) systems to absorb thermal expansion and contraction caused by changes in temperature and pressure.

•Aerospace industry

•Petrochemical industry

•Power generation

•Medical equipment

•Automotive industry

•Semiconductor industry: Metal bellows and expansion joints are used in the semiconductor industry to compensate for movement and vibration in vacuum chambers and other equipment.

How to select the right metal expansion joint for my specific application?

Selecting the right material for metal bellows and expansion joints is important to ensure they are durable and reliable in specific industry applications. Here are some factors to consider when selecting the material:

1. Temperature: The material should be able to withstand the temperature range of the application. Different materials have different temperature limits, so it’s important to choose a material that can handle the expected temperature range.

2. Corrosion resistance: In industries where corrosive substances are present, it’s important to choose a material that is resistant to corrosion. Materials such as stainless steel and Inconel are often used for their corrosion-resistant properties.

3. Pressure: The material should be able to withstand the pressure of the application. Different materials have different pressure ratings, so it’s important to choose a material that can handle the expected pressure range.

4. Flexibility: The material should be flexible enough to accommodate movement and vibration in the application. Materials such as Inconel and titanium are often used for their high flexibility.

5. Cost: The cost of the material should be considered in relation to the specific industry application. Some materials are more expensive than others, so it’s important to choose a material that is cost-effective for the application.

It’s important to consult with a manufacturer or supplier of metal bellows and expansion joints to determine the best material for a specific industry application. They can provide guidance and recommendations based on their expertise and experience in the field.

FEATURES
 
Absorb Axial movements (extension and compression).
Axial movement is the change in dimensional length of the bellows from its free length in a
direction parallel to its longitudinal axis.
 
Absorb Lateral movements.
Lateral movement is the relative displacement of one end of the bellows to the other end in a direction perpendicular to its longitudinal axis.
 
Absorb Angular and Torsional Movements.
Angular movement is the rotational displacement of the longitudinal axis of the bellows toward a point of rotation. Torsion refers to twisting one
end of the bellows with respect to the other end, about the bellows centerline.
 
Reduce Vibration.
Rubber expansion joints isolate or reduce vibration caused by equipment. The transmission
of vibration is reduced and they protect equipment from these adverse effects
 
Dampen Sound Transmission.
Rubber expansion joints tend to dampen transmission of sound because of the steel rubber interface of joints and mating flanges.
