The installation of a steam rotary compensator requires certain steps and precautions to be followed to ensure that it can operate effectively and absorb displacement in the piping system. Here are the general steps to install a steam rotary compensator:
Handling and storage：
During handling and storage, avoid impact and fall to prevent damage to interface and internal parts.
Preparation：
Check that the compensator meets the design requirements, including size, material, and working pressure.
Clean the inner and outer surfaces of the compensator to ensure that there are no foreign matter.
Centering Installation：
Concentric installation is achieved whenever possible to ensure smooth operation of the rotary joint.
Pay attention to the alignment of the rotary joint with the pipe to ensure that the axis is consistent.
Threaded connection(if applicable):
Verify that the thread direction of the inner and outer tubes is consistent with the rotation direction of the drum, and that the thread direction of the inner and outer tubes is consistent.
Hose connection：
Use a hose (metal hose with good disturbance is recommended) to connect the rotary joint to the pipe to avoid stress concentration caused by rigid connection.
Pre-offset assembly：
According to the direction of thermal expansion of the pipeline, the rotary compensator is pre-biased, and the pre-biased loading amount is usually half of the compensation amount, which helps the two ends of the compensator and the sliding pipe holder to return to the design position under the operating state, and ensures the lateral safe distance.
Fixation and support：
Install fixed brackets and sliding pipe holders to ensure pipe and compensator stability.
It is possible to use rolling brackets where conditions permit to reduce the effect of frictional reaction forces on the fixed bracket.
Connection and Sealing：
Use the correct gasket (e.g. metal wound gasket) for flange connection, thickness depending on the process.
Make sure all joints are well sealed to prevent leakage.
Commissioning and testing：
After all pipe holders have been installed, perform pressure testing of the piping system to ensure there are no leaks.
Check if the compensator can rotate freely without jamming.
Pre-run inspection：
Before the system is put into operation, check the installation of the compensator again to ensure that all components are installed correctly and that there are no factors that hinder its normal operation.
Please note that the specific installation steps may vary according to the manufacturer's instruction manual and the design of the piping system, so strict reference should be made to the product instructions and relevant engineering standards during installation.
