Division of labor for process pipeline maintenance
Thread Content
Hello everyone. I would like to ask: what is the minimum pipe size at which maintenance teams are responsible for handling the pipelines, and what is the pipe size at which operational staff take care of them? Are there any standards or regulations in this regard?
There are no such relevant standards or regulations. It is the responsibility of the user unit, which may hire relevant supervisors from outside.
What the original poster is asking is: for process pipelines of what diameter and below, are it the operators who replace gaskets, valves, etc., while everything else is handled by maintenance personnel? This does not meet industry standards; generally, it is around DN150 to 200. Also, when repairing or adjusting control valves or on-off valves with large diameters, disputes can easily arise with the production workshop; we use diameters in the range of DN150 to 200.
There shouldn’t be any rules for this. Generally, it is coordinated internally by the company itself. It should be determined based on the number of mechanics and production staff. If there are enough mechanics, they can handle all maintenance tasks; this falls under the responsibility of the functional department. If the maintenance cycle is short, production cooperation is definitely required. During maintenance, those with a diameter of DN100 or less (including 100) are usually handled by the production department, while those larger than 100 are handed over to the mechanical repair team. According to the maintenance plan, if there is enough time, all tasks will be handled by the machine repair team, with production ensuring safety and providing assistance. Before each maintenance task, we hold meetings with representatives from production, mechanical and electrical engineering, instrumentation, as well as safety and environmental protection teams, and then assign tasks accordingly. Raise any objections; if there are none, proceed. To avoid disputes during that period.
I think there should be a leading part, with another part complementing it.
There are no relevant regulations or standards; in our factory, tasks involving diameters of 3 inches or less are generally handled by the production team, while those with larger diameters are dealt with by the maintenance team.
This should be determined based on the nature of the maintenance work. Tasks that are not too difficult and require little effort can be handled by oneself, while other tasks should be carried out by professional maintenance personnel.
