Compensator fatigue test: design fatigue life by bellows compensator types and causes of failure can be seen that the stability of the bellows plane circumferential stability and corrosion resistance are its fatigue life that is related to the amount of displacement. Low fatigue life will lead to stability and corrosion resistance of the bellows fall. According to the test and experience with axial compensation, bellows fatigue life for the heating project should not be less than 1000 times. Bellows can not load-bearing, should be a separate lifting; in addition to the design requirements for pre-stretched or cold tight pre-deformation is strictly prohibited to use the bellows deformation method to adjust the pipe misalignment; installation process does not allow welding slag splashing into the bellows surface and by other mechanical damage; bellows components of all activities shall be stuck or limit the external component parts of their work activities. Most bellows failure is caused by corrosion by the external environment, thus making the structure of the compensator is designed, it can be considered isolated from external corrosive medium in contact with the bellows. As the finale to the outer compensator can be between the outlet end of the outlet pipe to increase the packing ring seal, which acts as a sleeve compensation, either to resist external corrosion media intrusion, gave bellows compensation increased by a security barrier, even bellows damage, compensation can also play a role and to avoid compensating bellows failure. Three-dimensional description of the three-dimensional corrugated compensator bellows compensator 3D ripple compensator (A-type): This series is mainly used for three-dimensional bellows and axial elongation axis thermal power plant boiler system hot air and gas pipeline to compensate for thermal expansion offset. This series of three-dimensional corrugated compensation according to the specifications prescribed by the nominal compensation, preparation of specifications from DN200 - DN1000 pipe joint compensator, a total of nine kinds. Note: The data in the table after the slash compensator allows for maximum deflection angle. Three-dimensional corrugated compensation 3D ripple compensator (B type): This series three corrugated compensator (B) by two to do a certain amount of axial compensation and do ≤ ± 3 ° angular deflection of multi-wave section of stainless steel bellows compensator in series into (in this series with four stainless steel bellows compensator nodal basis for i) toggle structure, composition can absorb the amount of three-dimensional expansion. Increase the amount of compensation as the design selection length sleeve compensator, reducing the angle compensation values ??are generally choose the design of cold-drawn 3/2 radial compensation, the compensation angle choice selection parameter list to be investigated.
