Expansion joints for catalytic startup
Thread Content
Before starting up the catalyst system, are all the expansion joints in use? How to put it into use? Are there expansion joints with automatic deformation detection? Thank you!
Can the expansion joints there be removed? If not, then it occurs as the system’s temperature and pressure increase.
Once in operation, proper markings should be made at the time of startup. The corresponding expansion amounts under cold and hot conditions need to be recorded. As operation proceeds, the temperature rises as well; it is necessary to monitor the expansion amounts and make comparisons. The scale should be checked every time the system is started up
The main steps involve removing the fixing bolts; one end of the limiting bolt must be movable. Initial cold-state markings should be made, and during the heating process it is necessary to monitor the amount of expansion to ensure that there is no conflict with anything on the platform
