How to remove the maintenance gasket

2017-04-28View Original

Thread Content

How to remove steel gaskets such as octagonal gaskets during maintenance? Since they remain in the groove for a long time, it’s difficult to take them out. Forcing the gasket sealing surface can cause damage, and using soft tools to strike it is not very effective. Seeking advice on skills.

Before maintenance and installation, applying some molybdenum disulfide can help a bit

It’s easy to bring them out after the event; everyone faces such challenges.

Large companies are professional; when we encounter such problems here, we just apply some lubricant to fix it.

I’ve handled grease before; it’s easy to install, but the coked gasket can’t be removed at all~~~

Whoever is in charge of guardianship is responsible; this must be considered improper guardianship. After removing the old gasket, the sealing surface of the flange should be cleaned promptly; installing a new gasket without first cleaning it properly is rather lazy. Hehe

It has nothing to do with supervision; it’s just that applying grease makes it difficult to remove the gasket during maintenance~~~ In our case, high-pressure octagonal gaskets often get damaged after being used just once~~~ Sometimes this is due to the material of the gasket itself, and other times it’s because of defects left over from improper installation by the person who carried out the work – things that you can’t see~~~ As a precaution, it’s better to replace the gaskets in high-risk areas. Saving money at the expense of safety isn’t worth it; it would end up costing more in the long run.

Yes, through repeated inspections and restarts, it was found that the water level for inspection was too high.

If you decide to hold someone accountable, you’ll find that maybe the entire set of gaskets will need to be replaced~~~~ By then, the manager will be stunned~~~ So, it’s fine to assign responsibility to individuals, but it’s important to consider the situation as a whole. A senior colleague once said something similar: assign responsibility to individuals, and impose fines on those who don’t meet the standards. A young man replaced the gaskets, but leaks still occurred no matter what he did; the manager held that person accountable, thinking that if he had done the work properly, there wouldn’t have been any leaks. He tried to handle it himself, but it still didn’t work~~~ In the end, it turned out to be a problem with the gaskets. When I replaced the gaskets myself (graphite wound gaskets), I went to the warehouse to pick out those that I thought met the standards; sometimes only half of a roll of gaskets were suitable. Later on, no one wanted to go to the warehouse to select gaskets for me~~~

Your personality makes it easy to offend people – is the warehouse really a place for someone with your talents? Purchasing water is such a complex process; be careful or you might get drowned trying to deal with it. Here, most people have their guardians ask the construction crew to go to the warehouse for mats; I’m one of the few who doesn’t do that, so I end up offending people unintentionally, haha

The workshop has its own warehouse~~~ They do things on their own, so of course they choose the best ones~~~ Otherwise, rework is so tedious~~~~
