Reorganization begins

How are the reactor inlet and outlet pipelines purged in the early stage of restart after reorganization?
Many modern reforming units are of large scale, with very large diameter pipelines at the reactor’s inlet and outlet; therefore, blast cleaning is quite dangerous. It is best to pay attention to the cleanliness of these pipelines during the construction phase, and to clean them directly before welding.
The heating furnace is directly connected to the collector pipe without flanges
Currently, the scale of continuous reforming is increasing, and the inlet and outlet pipelines of the reactors are quite large, making it difficult to carry out blast cleaning. During the piping installation phase of plant construction, strict construction management is required to ensure that the pipelines remain clean; it is also possible to avoid using blasting at the time of commissioning.
