The equipment from the old tower has been left there for a year; now that our workshop has resumed operations and plans to use this tower again, what parts of the tower should be checked first? ? Only then can we ensure that there are no problems during production.
Are you sure this is an old tower equipment from before, and not one that has been scrapped? :First of all, there’s the most basic pressure retention test, as well as an inspection of the corrosion status of the components inside the tower; everything needs to be checked, after all, it has been in use for such a long time. Other requirements need to be met in terms of processing; it depends on whether this tower is suitable or not
1. As the moderator said, are you sure this is an old tower equipment from before, and not one that has been scrapped? 2. Is it a pressure vessel? In that case, it is necessary to recheck whether the pressure, wall thickness, etc., meet the requirements. Corrosion conditions at welds, connections, and other areas. 3. Pressure holding tests, as well as tests for water pressure and airtightness, are required. 4. Other requirements must meet the process specifications to determine whether this tower is suitable. 5. Other requirements closely related to the process and production.
It’s an old tower, not a scrapped one; it’s also necessary to check whether the sealing surfaces are damaged and whether the holes are blocked, as well as to manually remove rust deposits inside the tower.
As long as it is not a scrapped tower, it can generally be used again after thorough inspection and repair. Just to be safe, all necessary checks must be carried out strictly.
In addition to what the original poster has said, it is necessary to analyze the areas prone to fluid accumulation, as well as those under high structural stress, and these areas should be inspected carefully.
For the owner’s old tower, it should first be inspected in accordance with TSG R7001-2004 \"Rules for Periodic Inspection of Pressure Vessels\", and an inspection report (issued by a qualified entity) must be obtained. Based on the data in this report, calculations shall be carried out by a party with design qualifications; thereafter, approval from the top management of the organization is required, and relevant procedures must be followed before the tower can be put into use.
