Oil-containing leak repair technology for heat transfer oil pipelines
Thread Content
Dear colleagues: When raising the temperature of the heat transfer oil pipes used for asphalt heating in our company to 260 degrees, we discovered a small leak at a welded joint in the pipes. However, since the system is currently operating normally, we do not want to stop it in order to repair the leak. Do any experts have any effective methods for fixing this leak? We would be very grateful for any guidance you can provide
This situation has also occurred here, and there’s no good way to deal with it
Are there any other good solutions besides parking? If we park the vehicle, the losses will be too great
I have indeed encountered similar situations; one company covered the cost on behalf of our factory. However, it usually lasts for three to four months; after that period, the vehicle still needs to be stopped for maintenance. Still, being able to last until the major repair is already good enough for production. I can give you a phone number to call and ask, but you need to negotiate the price hard; it’s best to sign a quality guarantee agreement. 13091271195
The leak can be sealed using pressure-based sealing techniques
Could the friend upstairs be more specific?
The temperature is too high, so conventional methods for sealing leaks will definitely not work; if the pressure isn’t high, riveting or clamping devices could be considered. It’s strange; weren’t any pressure tests conducted?
Thank you to all my friends. Pressure tests were also carried out, and the pipes were purged. At that time, the leak location was on the back side of the valve at a high altitude, so it was not easy to detect; if it had been detected, this would not have happened. Thinking about it now, it’s likely that during welding the welding rod wasn’t dried properly, which caused bubbles to form inside; over time, these bubbles led to leakage, at about one drop per 10 minutes.
That’s okay; in a few days, once it’s carbonized, it won’t leak anymore
Thank you to all the friends mentioned above. There was no other choice; for safety reasons, it was necessary to stop, clean it with nitrogen, and then carry out repair welding.
If there are sand holes in the pipes of a heating system, the leaks can be repaired by welding directly; I have dealt with such situations on site. Discussion QQ: 525224195
I think it can be welded. The key issue is that if there’s oil leaking, it’s difficult to carry out repair welding; and after the welding, there’s a risk of leakage again, which depends on the skill level of the welder
