1. corrugated compensator before installation should check its type, specification and pipeline configuration, must comply with the design requirements.
 

   2, with inner sleeve compensator should pay attention to the inner sleeve of the bobbin in the direction of the flow in the same direction with the media, hinge hinge type compensator is rotational plane should be consistent with the rotational plane displacement.
 

   3, need to be "cold" tight compensator, predeformation auxiliary components should be used in pipe installation is removed.
 

　4, it is forbidden to use corrugated compensator deformation method to adjust the pipeline installation error, so as not to affect the normal function of the compensator, reduce the service life of the components and piping, equipment, supporting the load.
 

　5, the installation process, do not allow the welding slag splash to the shell surface, do not allow the wave shell by other mechanical damage.
 

　6, piping installation has been completed, should be removed as soon as possible on the corrugated compensator is used as the installation of transport yellow auxiliary positioning components and fasteners, and switch to a specified position limit device according to design requirements, make the piping have ample compensation ability under the environmental conditions.
 

　7, corrugated compensator all active components shall be external components are stuck or limit the scope of its activity, should guarantee the active parts of normal movement.
 

　8, when the water pressure test, equipped with corrugated compensator pipe terminal time of the department of the fixed frame for reinforcement, make line do not move or rotate. For gas medium compensator and the connecting line, must pay attention to the water filling whether need to add temporary support. Hydrostatic test water cleaning fluid 96 chloride ion content is not more than 25 PPM.
 

　9, after the water pressure test, as soon as possible the water wave shell, shell surface dry and quickly will wave.
 

   10, contact with corrugated compensator bellows heat preservation materials should not contain chlorine.
