Exhaust Compensators

Exhaust Compensators
Stainless steel compensators are used in appliances, machines, apparatus and pipe systems where space
is restricted:
• To compensate for movement 
• To compensate for expansion
• To reduce tension
• To absorb noise and oscillation transmission
• To compensate for ground and foundation settlement
• As adapters to compensate for installation inaccuracies
• As dismantling pieces for fittings stainless steel compensators are flexible pipe connection elements and are used in a variety of industrial applications:
• Machine engineering    • Domestic industry
• Chemical industry          • Process plant engineering
• Gas and water supply    • Exhaust technology

STAINLESS STEEL BELLOWS
Structure
Axces stainless steel bellows are available in a variety of structures and versions.
The steel bellows is the flexible element of every compensator. It must fulfil the requirement for good movability with simultaneous pressure resistance.
Variable parameters (wall thickness, number of plies, convolution geometry, number of convolutions) determine the pressure resistance, movement absorption and spring rate (self- resisting force) of the bellows. Oneply, two-ply and multiply bellows are manufactured from various materials with different wall thicknesses.
The calculation methods ascertain the stability limits. The ability to withstand buckling is the prime
criterion for smaller bellows diameters, whereas in larger bellows diameters it is convolution stability.
Material qualities
Axces compensator bellows are manufactured from top quality sheet metal. Different material qualities are used to
cover the many operating conditions in various industrial applications. The outstanding characteristic of the steels
and alloys is their particular resistance to chemically aggressive liquid media. Please ask our Technical Consulting
Service for detailed information about the media resistance of individual materials.

Rating & Service Life

Stainless steel bellows, as a rule, are rated for a temperature of +20 ° C, the nominal pressure and a load of 1000 load cycles. One load cycle refers to the procedure beginning at zero position, from where the compensator moves to the maximum elongation (positive) position, back through the zero position to the maximum compression (negative) position, and back to the zero position.

Together with the tolerable operating conditions.
• Pressure      • Temperature
• Movement  • Number of load cycles

The following parameters can also influence the service life of compensators:
• Corrosion                         •High-frequency oscillations
• Sympathetic vibration   •Pressure shocks
• Temperature shocks      •Incorrect installation

Corrosion can be caused by incorrect selection or combination of materials, conveyance of aggressive media and inappropriate cleaning with chemical agents.
High-frequency oscillations and sympathetic vibration must be avoided by all means, because this will result in fatigue failure/fracture.
Pressure and temperature shocks must be avoided. It is important not to exceed the permitted maximum values.
Incorrect installation can be prevented by compliance with the installation and assembly instructions.
In the case of unrestrained compensators, the absence of fixed points can cause the pipeline to shift.
This usually destroys the compensator.Rating & Service Life
