There is oil leakage at the flange of the lubricating oil pump for my steam turbine; it’s not possible to stop the machine for repairs at the moment. I can only add more oil when its level drops. Do you have any sealants that can be used to plug the leak while the machine is still running and under pressure?;
Then you’re wasting a ton of oil there; what’s leaking isn’t oil, it’s money! I recommend a technology for you to consider: the Fushilan polymer composite online repair technology, which can address most oil leaks online. Oil-resistant, with excellent adhesion. However, without knowing the specific situation of leakage at the flange of the original poster, it’s difficult to draw a conclusion. My space has repair cases that you can refer to.
The technology for plugging leaks under pressure is already quite mature and well-developed; it involves manufacturing clamps, selecting sealant, and injecting the sealant. There are professional companies that specialize in plugging leaks under pressure; you can find them on Baidu.
May I ask where is the leak? Flange? There are many ways to address the issue with flanges; one can create a custom flange fixture and then choose an appropriate sealant based on temperature and the type of medium, allowing one’s workers to handle the task. Alternatively, one can turn to a professional company specializing in leak sealing services that can work without shutting down the system. Our company does this as well, haha. It’s just that your flange is probably quite small, so it’s not cost-effective to entrust the task to a professional company specialized in stopping leaks without shutting down operations. If there is a leak in the pipeline, the solutions include: 1. Using clamps – this is a temporary fix; it’s better to carry out a complete repair during scheduled shutdowns, such as by replacing the pipeline. 2. Synthetic repair: a permanent repair method whose strength is 10 times that of steel, its hardness is twice that of steel, and it is resistant to corrosion. The cost is very high. 3. Online replacement of damaged flanges or pipes without stopping the system is also costly; it is not cost-effective for smaller pipelines or flanges. I hope this can help you; feel free to communicate online if you have any questions.
