How are the equipment in coking plants inspected?
Thread Content
Question: How are the devices in a coking plant inspected by the quality supervision bureau? For example, are pressure gauges inspected one by one after removing them? Can the quality supervision bureau inspect transmitters? Can they inspect flow meters? Is it necessary to disconnect the pipelines and apply pressure to air storage tanks? And so on.
Keep in mind that the purpose of inspections is to ensure safe production without disrupting it; therefore, inspections should be carried out based on actual conditions. Some inspections involve taking samples for analysis, such as checking the product’s quality rate or water pollution levels, while others require on-site inspections.
Coking equipment is also equipment that requires careful inspection by professionals; even the slightest negligence can lead to accidents. New equipment generally undergoes safety tests before leaving the factory, and this information can be found in the user manual or in the project agreement. For equipment that is in use, regular inspections are necessary; while the appearance may be overlooked, it is the safety performance that matters. As long as the equipment is still within the warranty period, the manufacturer will send professionals to carry out maintenance, and the methods for inspection can be learned from these professionals. I am one of the engineers involved in coking design, so I have a good understanding of this area; we can learn from each other.
It should refer to professional special equipment.
For large devices related to safety, Party C’s supervision team and Party A’s engineering department work together in a professional manner to ensure compliance with various requirements. For smaller items, such as forms, they can be returned or exchanged during the trial operation phase, before the final handover
Gauge pressure meters and safety valves are equipment subject to mandatory inspection, and should be inspected at least once a year. Transformers should undergo high-voltage tests regularly by the power utility. Pressure vessels should undergo inspection tests on a regular basis. Primary instruments such as flow meters should be inspected annually.
