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:
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.
Bellows Systems engineering and technical sales staff can assist you in making right material selection based on your application.
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.
Manual and Install Notes of the Rubber Joint
1, The installation of expansion joints shall be in accordance with the expansion of piping construction drawings and installation instructions requested
2, Install expansion joint of the pipeline must be approx. to increase fixed by the orientation
and expansion joints can be made to play a role, so orientation and fixation of the settings must be in strict accordance with the design departments of the technical information. For orientation, the principle of setting a fixed support, please see "Bellows Expansion joints Installation Guide."
3, With a bellows expansion joint is formed with a thin stainless steel plate, so lost in moving, hoisting and welding should be careful not to hit the period, scratch, arc,weld spatter and other reasons to bellows damage
4, Should be removed before installation and piping bellows foreign body to ensure normal movement bellows
5, On a flow of media requests for expansion joint should be required to install the flow arrows
6, In order to make bellows in good working condition,can not install expansion joints in the deformation, including axial, lateral, turn transfer pipe installation error
7, Expansion joints installed, running in the system before moving to remove all painted yellow lose a fixed screw
8, Fabric fiber expansion joint is not subject to the tensile displacement due to the installation to the proper conduct of the pre-compression, the pipeline can not deflection, displacement and axial extension, should be noted that flexible ring of protection against scratches, installed as soon as possible to dismantle support board, so that in normal working condition
