The catalysis workshop is scheduled to stop undergoing inspections in 2016. We want to create a manhole on the regenerator; we’re not sure if that’s possible. What preparations are needed? Where would be the best location for such a manhole? Please advise~~~
Sure, you can open it wherever you want. However, the manhole must be prepared; the manhole cover and pipes need to be lined, and the removed walls also need to be lined and restored.
The last edit to this post was made by 678 on 2015-6-15 at 08:45. The question is whether it’s feasible to create a manhole. The following issues need to be addressed: 1. Manholes are usually quite large, with a diameter of at least 500 mm; after such an opening is created, a large dead zone forms in that area. It’s necessary to determine whether this will have an impact on the production process and product quality, and this requires your process engineers to conduct analyses and provide a conclusion； 2. Impact of openings on the equipment itself: 1) If the manhole is 500 mm or larger, such a large opening has a significant impact on the strength of the equipment itself ； 2) The high temperatures associated with drilling and welding also have a significant impact on the material of the equipment itself. Therefore, when drilling is required, it is necessary to consult the original equipment designer or the person responsible for the equipment’s design in order to have the drilling process verified and planned accordingly. The designer’s design will specify the required materials and construction requirements. For your reference
The current progress is that it is technically possible to have an opening; the previous equipment drawings have been found, and preparations are being made for the equipment. Thank you~~~
