How to deal with small leaks in the negative pressure pipes of coke ovens?
What kind of pipeline are you talking about exactly? Is the pressure high? If the pressure is not high and it’s a small leak, a specialized imported sealing material from abroad can be used to seal it first, followed by welding in steel plates.
1. Seal with epoxy resin and fiberglass cloth； 2. Use rubber sheeting combined with steel plates to create a hoop seal ； 3. As mentioned above: Use professional sealant materials to seal the leak first, and then weld steel plates on top. ” I have tried all the methods mentioned above: first, to check the size of the gaps; second, to consider how the location affects the construction process; and third, to pay attention to safety during welding (to prevent air from getting in, to ensure that the gas contains the proper amount of oxygen, and it may be advisable to work while the coke oven is not in use)
I agree with what was said on the 3rd floor: first, determine the size of the leak, and then use professional methods such as sealing the leak, applying clamps, brushing epoxy resin, and using fiberglass cloth – these approaches can effectively resolve the issue.
